Which Driver should I Use?

HP DesignJet printers and plotters are supported by these drivers:

PostScript Adobe PostScript 8.5.1 Driver

Microsoft PostScript Driver

• The supplied drivers are versions, customized by HP, of those provided by:

- Adobe (for the Macintosh and for Windows 3.1 and Windows 95) - Microsoft (for Windows NT 3.51 and 4.0 on a PC).

They convert vectors, text and raster images to PostScript, with additional functionality speciﬁcally for this printer.

HP-GL/2 and HP DesignJet Printer Driver (HP-GL/2 and HP RTL) for Microsoft Windows 3.1 HP RTL and Windows 95 (v2.5)

HP DesignJet Printer Driver (HP-GL/2 and HP RTL) for Microsoft Windows NT 4.0 (v2.00)

• These drivers convert vectors, text and raster images to HP-GL/2 and HP RTL which are used by the printer.

AutoCAD HP-GL/2 Driver for AutoCAD (v4.x)

• This driver supports AutoCAD releases 10, 11, 12, 13 and 14. It converts vectors, text and raster images to HP-GL/2 and HP RTL which are used by the printer.

Software Application Notes 4 Which Driver should I Use? General Considerations for Drivers

If you are using AutoCAD, you should use the AutoCAD driver. This driver also supports various pen plotters and other printers, including HP LaserJet printers. Full details may be found in AutoCAD Drivers for HP Plotters and Printers.

Otherwise, use the appropriate driver for your operating system. If you have a choice of how you produce images from your application, choose PostScript if it is available.

Software Application Notes 5 What Affects the Overall Performance of My System? What Affects the Overall Performance of My System?

There are two signiﬁcant components to performance:

1. The processing time (also known as the “click-to-start” time): the time between initiating a request for printing (clicking the Print button, for example) and when the printer actually starts printing. 2. The mechanical printing time: the time taken for the printer to print.

Processing Time The following factors affect the processing time:

• The processing speed of your computer.

The higher the processing speed, the faster your printing will start.

• On your Apple Macintosh, whether you request the print driver to perform foreground or background spooling.

Depending on the speed of your computer and the driver you are using, background processing can take considerably longer than foreground processing.

One-pass foreground printing is available with the Adobe PostScript driver version 8.5.1 (PostScript 3). This feature gives much better performance than previous PostScript level 2 drivers when you use foreground printing.

• Whether you have requested Queue=On or Off (in the Queueing & Nest- ing menu).

If you have just one print, it is beneﬁcial (in terms of performance) to set Queue=Off. This is because any print for which queueing is requested is stored in a queue area in the internal hard disk of the printer. This storing of data takes time.

However, complex prints that are printed with Queue=Off may experience a degradation in print quality. This is because the printer may stop during printing while further processing of the data takes place. Specifying Queue=On overcomes this problem because the entire print is stored in the printer’s memory.

If you have a succession of prints, or if your printer is on a network and serves several users, the total print time for the series of prints will be

Software Application Notes 6 What Affects the Overall Performance of My System? improved by requesting Queue=On, as the printer is able to overlap one user’s print time and the next user’s processing time.

If you are nesting plots, you must also enable queueing.

Enabling queueing allows the requesting of additional prints without incur- ring any extra processing time.

• Whether you are using Ink Emulation.

If you use ink emulation (Options → Color Management → SWOP, Euroscale or TOYO), there is an overhead in the processing time (see page 33 for information speciﬁc to CorelDRAW!). Specifying No Color Adjustment or Enhanced native gives better performance.

Both No Color Adjustment and Enhanced native give a wider color gamut, but color consistency across different media is not guaranteed.

No Color Adjustment processing may produce less glossy prints and may cause cockle and banding in solid area ﬁlls. Enhanced native processing may also produce banding in solid dark area ﬁlls.

However, ink emulation (SWOP, Euroscale or TOYO) causes the printed colors to emulate the system selected, and ensures color consistency across HP media. Ink emulation is slower because the color model needs to be converted.

* Note that the setting in the driver overrides any setting on the printer’s front panel.

• Whether you have requested ASCII or Binary ﬁle encoding when you print from the application.

ASCII files are about twice the size of binary ones, so they incur a penalty in performance. However, ASCII files can be printed on any platform, including Windows NT. Binary files may incur compatibility problems, and may not be used on Windows NT. On Windows 95, use binary encoding with a driver setting of tagged binary for best performance. JPEG encoding is preferred, if it is available.

Software Application Notes 7 What Affects the Overall Performance of My System? Printing Time The following factors affect the printing time:

• The size of the image on the page.

An A0-size print takes longer than an A1-size.

• The media type.

Printing on non-glossy media is faster than on glossy media, where the drying time for the ink is longer, and the printer may need to pause between passes of the print head to allow time for the ink to dry. Printing on paper is generally faster than on vinyl or ﬁlm.

• The print quality you have selected.

Photo gives the best quality, but is slower. Economy is the fastest but at the expense of poorer quality. Productivity is fast and with good quality.

• Environmental conditions.

The humidity and temperature affect the drying time of your print. The higher the humidity or the lower the temperature, the longer the drying time is.

Software Application Notes 8 How to Print Big! How to Print Big!

This section is intended to help you print large “banner” pages on your HP Design- Jet 3500CP. “Banner” pages are really big pages. Even though the HP DesignJet printers support rolls of paper up to 54 inches wide and 150 feet long, the applications, the PostScript drivers and the operating system itself have limitations that make it sometimes tricky to get really big pages printed.

These three examples try to explain what those limitations are, and how to overcome them. Please note that the techniques explained here are workarounds to limitations of the applications, systems and drivers. They make your life easier, pushing the limits of what can be printed. But they won’t solve all the problems: it’s still impossible to image a whole roll of paper (54 inches by 1800 inches) from PageMaker 6.5 for example. If you have such a need, you might want to investigate what tools like PosterWorks or other banner applications can do for you.

1. The easy case: Suppose you want to print a 54-inch by 100-inch banner from CorelDRAW! 7.0 applications under Windows 95. (Also for Photoshop and Freehand, under Windows 95; see supporting large below for Macintosh.) custom page sizes CorelDRAW! 7.0 can deal with documents up to 1800 by 1800 inches. The Win- dows 95 PostScript driver supports custom page sizes up to 54 inches by 129 inches. So, to print a 54-inch by 100-inch banner, the procedure is simple:

1. Deﬁne a 54-inch by 100-inch custom page in the HP DesignJet 3500 CP PS3 driver: In the File menu, choose Print Setup → Properties → Page Size → Custom Page X → Custom to deﬁne the new page size. 2. Create a 54-inch by 100-inch document: In the Layout menu, choose Page Setup → Page Size and click the Set From Printer button. 3. Create the drawings on your page, and print them.

A similar technique can be used in Macintosh applications:

1. Select your document page size in the HP DesignJet 3500 CP PS3 driver; most applications include a custom page size, which is the imageable area. 2. Create your document: in the Page Setup dialog box, choose Custom Page Default and set the width and height or add a new page. Go back to Page Setup and select Page Attributes, where you must select the new paper size. 3. Make sure that you account for the margins when you create the custom page size.

Software Application Notes 9 How to Print Big! 2. A little trickier: Now let’s imagine that you want to print a 54-inch by 150-inch banner from HP scaling to CorelDRAW! 7.0 under Windows 95. (This technique applies to other applica- custom page sizes tions in the Windows 95 environment. Similar support is available from HP’s to overcome DesignJet Drivers web site [http://www.hp.com/designjet/drivers.htm] for the Ap- application ple Macintosh with a driver plug-in.) limitations CorelDRAW! can create a 54-inch by 150-inch document. But the biggest custom page size that the Windows 95 PostScript driver can send to the printer is 54 inches by 129 inches (see Table 3 on page 31, and there is no 54-inch by 150-inch predeﬁned page size). The driver’s limitation is inherent in the Windows 95 printing architecture. Your Macintosh application may support up to 54 by 273 inches, which is the current limit of the Adobe PS 8.5.1 driver (see Table 2 on page 15).

HP provides you with a scaling feature that solves the problem. These are the steps to follow to get this 54-inch by 150-inch page size out of the printer:

1. Deﬁne a custom page size in the driver that has the same proportions as the 54-inch by 150-inch banner, but that ﬁts within the driver’s limitation; 27 inches by 75 inches would be suitable, for example. (The bigger the original page size is, the better—we want to minimize the scaling applied, to maxi- mize the print quality.) 2. Create a 27-inch by 75-inch document. 3. Create the drawings. 4. Use the HP scaling feature to scale the 27-inch by 75-inch document up to a 54-inch by 150-inch document:

In the File menu (under Windows), choose Print Setup and click Proper- ties. In the Graphics tab, set Enable scaling and click Scaling options. In the Scaling options dialog box, choose Scale to this standard page size and pick the ﬁrst option in the list below: Custom page size.

On your Macintosh, the equivalent settings are in the File menu, Page Setup, select HP Scaling. Three options are available there: • Scale to a standard page size • Scale to a percentage • Scale to a page width. Deﬁne the 54-inch by 150-inch page size you want to scale to. At this point, the Scaling options dialog summarizes the scaling that is going to be used in the Scaling group—from [the original document size]: 27 inches by 75 inches, to [the ﬁnal scaled up paper size]: 54 inches by 150 inches.

Software Application Notes 10 How to Print Big! 5. Print the document.

Why does this work? The scaling feature that we’ve just used is a unique HP feature that is designed to overcome the application’s and driver’s limitations in terms of large format printing. It allows you, given an “original” page size, to deﬁne a “destination” page size. The best scaling from the original to the destination page is then applied, centering the scaled original page on the destination page, and preserving the drawing’s proportions.

If Wo and Ho are the width and height of the original page size (27 inches by 75 inches in the example above), and Wd and Hd are the width and height of the destination page size, the scaling applied is the biggest scaling factor that doesn’t produce clipping: min (Wd/Wo, Hd/Ho).

That is why it is important to use original and destination pages that have the same proportions.

Note that the scaling is applied to the page imageable area. We’ve been ignoring margins so far for the sake of simplicity. But if Wm and Hm are respectively the printer’s side and top/bottom margins, the scaling factor applied is: min ( (Wd-Wm)/(Wo-Wm), (Hd-Hm)/(Ho-Hm) ). (See also the note about margins on page 32.) It is the printable areas of the original and destination that are proportional.

Note: The necessary resolution for your images is around 150dpi times the scaling factor, in the case of printing in Photo mode and 75dpi times the scaling factor if you are printing in Productivity mode, to achieve good results.

Software Application Notes 11 How to Print Big! 3. The worst case: Finally, let’s change application and print a 54-inch by 150-inch banner from HP scaling with PageMaker 6.5 under Windows 95. This method also applies to all applications only a PPD under Windows 3.1 or Windows NT, and to PageMaker on a Mactintosh.

We are now facing many limitations: The biggest document that can be created with PageMaker 6.5 is 42 inches by 42 inches; Page Maker does let you access the driver features, but it also reads the driver’s configuration file (PPD file) for itself, and manages the corresponding features. Because it does that, PageMaker is not capable of providing the “Fit to custom page size” used in the previous example. But it does allow you to scale up to one of the predefined page sizes. However, there is no predefined page size such as 54 inches by 150 inches!

You can print the 54-inch by 150-inch document from PageMaker 6.5 under Windows 95, combining the “Fit to standard page size” feature with the printer’s Inked Area feature, as follows:

1. Create a PageMaker 6.5 document that has the same proportions as 54 inches by 150 inches, and that ﬁts the PageMaker 6.5 limits: 15.12 inches by 42 inches would do. Note: Make sure you include the margins in the custom page size. 2. Create the drawings. 3. Select Fit to Standard Page Size: 54 inches by 1800 inches. On your Macintosh, set the Scale to value in the Printer Speciﬁc Options dialog of the Print menu. 4. Select Page Format → Size → Inked Area on the printer’s front panel. 5. Print.

Why does it work? As explained in the previous example, the scaling applied is min (Wd/Wo, Hd/Ho).

In this case, the minimum is clearly Wd/Wo. So the scaling will produce a very long narrow image, where the destination page has a huge blank area on the top and bottom. The front panel Inked area feature will then skip the top and and bottom blank areas.

Now if your original page already included some blank areas at the top or bottom, the front panel’s inked area will also cut them out of the ﬁnal page, not respecting the proportions of the original design. To overcome this last problem, you might try to add white pixels at the top and bottom of your document; as they are not visible on the ﬁnal output, they will preserve the proportions of your document.

Software Application Notes 12 Using the Adobe PostScript 8.5.1 Driver Using the Adobe PostScript 8.5.1 Driver

The PostScript 8.5.1 driver has several new features: - Custom page sizes - Foreground printing - Updated user interface - PostScript 3 support.

• You can see the dimensions of the page you will print on by clicking on the image on the left on the Page Setup dialog box.

• The Adobe PostScript 8.5.1 driver supports Custom page sizes. Go to the Custom Page Default tab in the Page Setup dialog box. There you can create your customized sizes and give each one an appropriate name.

Software Application Notes 13 Using the Adobe PostScript 8.5.1 Driver For optimal performance with your Macintosh, use foreground printing.

Using the Adobe PostScript 8.5.1 Driver with Spoolers

If a Novell spooler rejects a printing connection due to insufﬁcient user privileges (queue security option turned on) or an internal error, the driver may hang indeﬁnitely.

Netware 3.11 may cause the driver to download fonts more often than necessary, resulting in poor printing performance.

Versions of Netware prior to 4.0 do not support the Adobe PS driver’s Auto Setup capability. In these environments, manually select the appropriate PPD for your printer. For more information, see the chapter “Selecting a PPD” in the HP DesignJet Printing Guide for Macintosh.

In general, spoolers that do not comply with version 3.0 of Adobe’s PostScript Language Document Structuring Conventions may not take advantage of PSPrint- er’s advanced features, or they may exhibit other printing problems.

You should note the following considerations when you use the PostScript driver with your HP DesignJet 3500CP printer and these applications. Table 2: Page Sizes and Scaling (Macintosh Applications)

Maximum document Maximum driver page size (inches) [a] custom page size (inches) [b]

Microsoft Word 21 × 21 54 × 273

Adobe PageMaker 42 × 42 45 × 45

Macromedia 210 × 210 54 × 273 Freehand

Adobe PhotoShop 416 × 416 54 × 273

a. This is the maximum page size that can be set in the application. b. This is the maximum custom page size that you can specify without scaling.

All the above applications use the PostScript Printer Descriptor (PPD) file, and allow you to fit the print to one of the driver’s standard predefined page sizes. They also let you scale your print to one of these predefined page sizes.

Please access HP’s DesignJet Drivers web site (http://www.hp.com/designjet/ drivers.htm) to download a plug-in that supports scaling to a custom page size; it is not on the CD-ROM.

Software Application Notes 15 Macintosh Applications Halftoning Don’t use application halftoning when you scale, because you will ﬁnd that the halftone screens are also scaled.

Oversize Margins If you set Page Format → Size → Inked Area on the printer’s front panel, this will prevent additional margins being set in the header or footer of your printed page when you scale your print. This applies especially if you are using a very large scale factor or producing prints longer than 72 inches. You should set this as a default especially if you frequently use custom page sizes.

Adobe Persuasion Adobe Persuasion 4.0 is incompatible with the Adobe PS 8.5.1 driver and ignores 4.0 the settings speciﬁed in Page Setup and Print. Use the PSPrinter 8.3.1 driver to print correctly.

Posterworks 4.0 Direct connection (PAP) printing is not supported. Very long prints can time-out due to AppleTalk restrictions.

Software Application Notes 16 QuarkXPress® QuarkXPress®

Installation QuarkXPress 3.1, 3.2 and 3.32 use a special file to print correctly. (QuarkXPress 3.32 does not require this PDF file. We recommend that you use the PDF file from the driver installation if you want to use custom page sizes.) To install the file:

1. Locate the folder containing your copy of QuarkXPress. 2. Open the HP DesignJet folder on your hard disk (or the name you entered during installation). 3. Drag the HP DesignJet 3500CP PDF ﬁle from the HP DesignJet folder to the PDF folder in your QuarkXPress folder. 4. Then you can open QuarkXPress for printing.

QuarkXPress 4.0 does not use PDF ﬁles. Instead it uses the PPD ﬁle that is installed in your system at the time of driver installation.

Custom Paper In order to be able to use cutomized pages from the driver, QuarkXPress must be (QuarkXPress 3.x) set up to use the PDF ﬁle for the HP DesignJet 3500CP (see above).

PostScript Driver Use the supplied “Connectivity Software” CD-ROM to install the driver for Mac- intosh. This is the Adobe PostScript 8.5.1 driver.

Paper Size In the File menu, select the Page Setup submenu and go to the QuarkXPress (QuarkXPress 3.x) tab. Select, at Printer Type, the printer model you are using (HP DesignJet 3500CP PS3).

If you are using the PDF ﬁle for the HP DesignJet 3500CP (see above for installation instructions), the Paper Size entry is grayed out. Ensure that you have set up the Paper Size in the Page Setup dialog box. Remember that you should

Software Application Notes 17 QuarkXPress® use the HP DesignJet 3500CP PDF ﬁle if you want to deﬁne custom page sizes.

If you did not install the PDF, QuarkXPress uses the HP DesignJet 3500CP PPD. Then the Paper Size entry is the value used for printing. Ensure that this is the same as that set in the Paper entry since the Paper Size setting overrides the Paper setting.

Note: If you want to cut the page exactly, you can print the registration marks (or “crop marks”) from the application. In this case, select a Paper Size big enough to hold the document plus the registration marks and the margins.

Paper Size In the File menu, select the Page Setup submenu and go to the QuarkXPress (QuarkXPress 4.0) tab. Select, at Printer Type, the printer model you are using (HP DesignJet 3500CP PS3).

Software Application Notes 18 QuarkXPress® The Paper Size entry is the QuarkXPress 4.0 setting for the page size to be used for printing.

The Adobe PostScript 8.5.1 driver and QuarkXPress 4.0 support custom page sizes. However, QuarkXPress limits this custom page to a width of 48 inches. To use a bigger page, you can follow the recommendations below, or refer to the section A little trickier... on page 10 for more information.

1. Create a QuarkXPress document which has the same proportions as your required page size, and which is within the QuarkXPress limits. For example, for a page size of 54 inches by 150 inches, 15.12 inches by 42 inches would be suitable.

Note: Make sure you include the margins in the custom page size.

2. Create the drawing.

3. Select Scale to 54 inches by 1800 inches in the Printer Speciﬁc Options dialog of the Print menu.

4. Select Page Format → Size → Inked Area on the printer’s front panel.

5. Click on Print.

For more information on this technique see “How to Print Big!” on page 9.

Software Application Notes 19 QuarkXPress® We recommend using HP halftoning by selecting Printer halftone in the application, and set Application Halftoning to Disallow in the driver.

Screening You should not use the QuarkXPress screening (or halftoning) algorithm. (Half- toning is the method of placing dots in order to obtain non-pure colors from a limited number of pure ones.)

• Set Application Halftoning to Disallow in the Print → Printer Speciﬁc Options dialog box (available from the File menu) to select DesignJet halftoning or screening. This mixes the four color planes in a random way, avoiding moiré patterns.

• However, if you must use QuarkXPress halftoning (which does not work correctly with the color maps, closed loop color and ink emulation), select Use PDF Screen Values from the QuarkXPress Page Setup dialog box. In the driver, set Application halftoning to Allow.

You will obtain different colors depending on your selection. The printer’s halftoning produces slightly lighter results.

Printing When you are ready to print, select the Print option from the File menu. The printer submenu will appear. Make whatever choices you want (number of copies, pages to print, destination, and so on). Use the Printer Speciﬁc Options if you want to change any of the output settings. (Refer to theHP DesignJet Printing Guide for Macintosh for more information on this option.) Remember that you should select Disallow in the Application Halftoning entry of the Printer Speciﬁc Options dialog box, to override the default QuarkXPress halftoning algorithm.

Software Application Notes 20 QuarkXPress® IMPORTANT: Printing from QuarkXPress v3.3.2 may result in a system error. You are strongly recommended to remove the “Balloon Help” ﬁle from the QuarkXPress folder to avoid this particular problem.

The Lightness setting does not work with QuarkXPress. You will be able to access the feature and adjust its setting, but there will be no visible effect in the printed image.

Color Management PANTONE Colors:

• If you use PANTONE colors from tables within the application, select SWOP as the emulation to use (in the Color Management entry in the Printer Speciﬁc Options dialog box). This method of selecting PANTONE colors is simpler because you do not need to concern yourself with the media or with halftoning.

• You may also use the PANTONE tables designed for use with the HP DesignJet 2500CP printer and some speciﬁc media and halftoning. PANTONE tables for the HP DesignJet 3500CP printer will be available through the driver section of the HP web site (www.hp.com/designjet/drivers.htm).

Imported Images:

• If you import images from Adobe Photoshop, you are recommended to use EPS RGB to get the best color accuracy, since PhotoShop includes the PostScript code to match colors across different devices, when it generates EPS ﬁles with RGB data.

• If you import CMYK images, you should select the appropriate color standard (SWOP, EuroScale or Toyo) in the Color Management entry in the Print Options dialog box. Then the colors printed on the DesignJet will emulate the colors of that standard. If you send CMYK data with No Color Adjust- ment and the color values you send to the printer are inappropriate, the printer may use an excessive volume of ink (more than 200% ink density) which will saturate your media and could, in extreme cases, result in serious printhead damage. See the notes on Ink Emulation on page 7.

Windows NT In Freehand 7.0 under Windows NT 4.0, the Fit to Page option and scaling to a percentage value in the driver do not work if you fail to select the Use PPD option in the application.

Printing Screening: By default, Adobe Illustrator for Macintosh prints images in a “clus- ter” type of screening. To achieve the best print quality, use the “HP Scatter Screen Technology” that is available in the HP DesignJet series printers. This places dots in a random matrix that avoids patterns in area ﬁlls. From the Document Setup dialog box, select Use Printer’s Default Screen, and set Application Halftoning to Disallow in the Printer Speciﬁc Options dialog box.

PostScript Driver Use the supplied “Connectivity Software” CD-ROM to install the driver for Mac- intosh. This is the Adobe PostScript 8.5.1 driver.

Printing Length Limitation: PageMaker can accept a maximum page size of 42 by 42 inches. Even if the printer can print larger images, selecting a larger page size than this in the driver will result in a clipped image; the drawing is shifted and incomplete. See The worst case... on page 12 for how to overcome this limitation.

Imported Images:

1. If you import images from Adobe Photoshop, you are recommended to use EPS RGB to get the best color accuracy, since PhotoShop includes the Post- Script code to match colors across different devices, when it generates EPS ﬁles with RGB data. 2. If you import CMYK images, you should select the appropriate color standard (SWOP, EuroScale or Toyo) in the Color Management entry in the Print Options dialog box. Then the colors printed on the DesignJet will emulate the colors of that standard. If you send CMYK data with No Color Adjustment and the color values you send to the printer are inappropriate, the printer may use an excessive volume of ink (more than 200% ink density) which will saturate your media and could, in extreme cases, result in serious printhead damage. See the notes on Ink Emulation on page 7.

Printing Screening: By default, PhotoShop uses its own screening, resulting in a printout that shows patterns in area ﬁlls.

In the Page Setup dialog, go to the Adobe Photoshop tab and set the Half- tone Screens to Use Printer’s Default Screens. Without this setting, you will not get the true color or dynamic range of values necessary for a good quality print. This setting turns on HP Scatter Screen Technology.

Software Application Notes 27 Adobe PhotoShop Preview: Before printing, you can check the layout of your ﬁnal print by clicking on the box at the bottom right corner of your image.

Also, if you are using the separation table from the HP DesignJet 3500CP, activate the Gamut Warning in the Mode menu, when you print or export ﬁles to other applications.

Color Management PANTONE Colors:

Choosing the Color Format: PhotoShop lets you send images in RGB, CIELab (Lab) or CMYK format. For the best color ﬁdelity compared with the calibrated screen original, send images in the same format as the original to the DesignJet (if Lab, send in Lab; if RGB, send in RGB) and let the printer do the conversion to its native CMYK format. If you have a choice for the original, Lab is in general preferable to RGB, though RGB works well in most cases.

Software Application Notes 28 Adobe PhotoShop If you select RGB format, PhotoShop uses the device-independent color path in the printer, which is a PostScript feature allowing colors to be converted consis- tently among different devices. As a result, RGB colors are received by the printer, and the PostScript interpreter in the printer uses a device-independent color path (one of the stages of the process uses a Color Rendering Dictionary) to perform the conversion to CMYK.

In addition, if you send RGB data, changes to the gamma setting in the PhotoShop Monitor Preferences dialog box will affect the overall lightness of the printed colors; reducing the gamma setting results in lighter colors printed, and increasing it results in darker colors printed.

If you want your document converted to CMYK in PhotoShop to be printed on a DesignJet, either directly from PhotoShop or from another application, use the DesignJet Color Separation Tables for the conversion from RGB to CMYK; they are on the driver diskettes.

Saving Images to be Imported into Other Applications: If you save an image from PhotoShop as an EPS file, do not include screening in it. Otherwise, when you print the EPS file from another application, your output will use PhotoShop’s screening, which shows patterns in area fills. You are also recommended to save the EPS file in RGB format. In that way you will achieve accurate colors in the application that does the printing, because PhotoShop includes device-independent color-path code in the RGB files, allowing a consistent conversion to CMYK values.

Similarly, when you save an image as a TIFF ﬁle, to be imported into another application, you are recommended to save it in CMYK format. If you use Pho- toshop’s Separation Setup for the conversion from RGB to CMYK, remember to select Ink Emulation as the Color Management option in the driver at the time you print your ﬁle. Otherwise, if you use an HP DesignJet Color Separation Table for the conversion, you will need to selectEnhanced Native or No Color Adjustment as the Color Management option in the driver at the time of printing. Note that color separation tables for the HP DesignJet will be available in the driver section of the HP web site (www.hp.com/designjet/drivers.htm).

Printing Scanned Resolution and Image Size: What is the best resolution needed for scanning an Images image that will be printed later on an HP DesignJet 3500CP?

The color resolution for this printer in Best mode when printing PostScript is 600 dpi. However, if you send to the DesignJet a 600 dpi image with its original size identical to the desired print size (that is, with no scaling applied), there will be too much information for the printer. This is because the DesignJet uses a a group of dots to simulate every non-pure color from its four inks (halftoning or

Software Application Notes 29 Adobe PhotoShop screening). You may then experience memory problems because you sent too much data.

The image’s resolution should not exceed 150 pixels per printed inch, again as- suming that the original size matches the paper size on which you are printing. A larger value will not improve the appearance of the image, but merely take longer to print. Avoid sending images with resolutions lower than 75 pixels per inch, which may make the image break up into large pixel blocks. You are recommended to use a value between 100 and 150 pixels per inch.

To improve performance, print the ﬁle with JPEG set on. Also, if you scale an image set Interpolation On in the Page setup dialog box.

If your scanned image is smaller than the ﬁnal print you want, you will need to use Scaling; multiply the previous numbers appropriately (for example, if you use a 200% scaling factor, double the resolution for each dimension).

If you have already scanned an image at too high a resolution and you are having disk space problems, reduce its resolution under the Image Size selection in the Image menu (the File Size box should be deselected in order to reduce the information in the image).

Overall Clarity of the Printed Image: If you have adjusted the monitor gamma so that the image appears correct on your screen (using the PhotoShop Monitor Preferences dialog box), and you obtain printed images that are too dark compared with your scanned images, adjust the lightness setting in the driver. You are not recommended to use the Monitor gamma for this purpose, unless you are saving the image in RGB EPS format, in which case the saved ﬁle will include the effect of the gamma change.

You should note the following considerations when you use the PostScript driver with your HP DesignJet 3500CP printer and these applications.

Table 3 applies to Windows 95. (See below for Windows 3.1 and Windows NT.) Table 3: Page Sizes and Scaling (Windows Applications)

Maximum document Maximum driver page size custom page size (inches) [a] (inches) [b]

Corel Photopaint 312 × 312 54 × 129

Aldus PageMaker 42 × 42 45 × 45

Macromedia 44 × 44 54 × 129 Freehand

Adobe PhotoShop No limit 54 × 129

a. This is the maximum page size that can be set in the application. b. This is the maximum custom page size that you can specify without scaling.

Software Application Notes 31 PC (Windows) Applications Pagemaker does not allow you to scale to a custom page size. (See The worst case... on page 12 for how to overcome this limitation.) The other applications in the table allow you to scale to a maximum custom page size of 54 × 1800 inches. This is the largest page size that can be scaled to in the printer. The same scaling factor is applied to both width and length.

Windows 3.1 and The same values as in Table 3 apply to Windows 3.1. Only the “maximum doc- Windows NT ument page size” applies to Windows NT environments, because you cannot set a custom page size in Windows NT. You cannot scale your print to a custom page size in Windows 3.1 or Windows NT.

Halftoning Don’t use application halftoning when you scale, because you will ﬁnd that the halftone screens are also scaled.

Margins Although your Windows application correctly reports the 18mm side margins on your computer screen, drawings located between 15mm and 18mm from the document’s side will be printed, when you might expect them to be clipped.

If you use the second of the techniques for producing very large images (see page 10), you should be aware that the scaling also applies to the part of the margin between 15mm and 18mm, so you may see margins that are slightly larger than the 18mm you expect.

Using the Printer in HP JetAdmin can be used in your PC so that your printing by-passes any spooler. Windows 95 Refer to the JetAdmin CD-ROM for more information.

Software Application Notes 32 CorelDRAW! CorelDRAW!

Page Size CorelDRAW! 5.0 has a limitation in the size of the document that you can deﬁne. Limitation The largest page size supported by CorelDRAW! 5.0 and previous versions is 30 inches by 30 inches. To print larger pages, you may need to use the Scaling feature (see below for guidance on how to scale your images).

CorelDRAW! 6.0 and later versions do not have this limitation.

Memory Size Some CorelDRAW! documents may result in big PostScript ﬁles, that take a lot of memory and time to be printed. You can try to reduce the time needed for the ﬁle to be processed by using the Scaling feature, that is, by specifying a smaller document page size in CorelDRAW! and scaling it inside the printer.

Processing Time If you use ink emulation, there may be a signiﬁcant overhead in processing certain CorelDRAW! ﬁles. Try changing the color option in the driver interface to No Color Adjustment or Enhanced Native (see page 7 for more information about this option). To change the color option in your driver:

• In Windows 95, go to File → Print → Properties → Device Options → Color Control.

• In Windows NT, go to File → Print → Properties → Advanced → Print- er Features → Color Management.

Scaling in The recommended way of scaling using CorelDRAW! is to scale to a speciﬁc CorelDRAW! page size. You should ensure that the page size in the CorelDRAW! Layout → Page setup is the same as that in the driver’sPrint → Properties → Paper tab.

Then in Windows 95, set the Enable Scaling button in the File → Print → Properties → Graphics tab, select Scaling Options, pick Scale to this standard page size and set the appropriate size.

Or in Windows 3.1 or 3.11, set the Enable Scaling button in the File → Print → Properties → Feature tab, select Scaling and set the appropriate size.

Other possibilities for scaling: A second option is to use CorelDRAW!’s scaling by selecting the source size in the Page → Setup → Layout dialog box, and the target size in the File → Print → Properties → Paper tab. Then in the File → Print → Options set Fit to Page under the Layout tab.

If you scale using the front panel, both the scaling factor and the paper size for printing are taken from the front panel; however, although thePaper Size deﬁned in the driver’s dialog box is not used as the size of the ﬁnal printout, it is used for

Software Application Notes 33 CorelDRAW! other purposes, so it should be properly set. Follow these steps to scale an image from the front panel:

1. Ensure that the Enable Scaling button in the File → Print → Properties → Graphics tab is not set. 2. Set the Page Size you want to print on the front panel (Page Format). 3. Set Fit to Page on the front panel (Page Format → PS Scale → Fit to Page).

If you want to scale a standard page with no margins, for example, a full Letter size, you need then to select Full Bleed US Letter size in the driver’s dialog box. Otherwise some part of the image will be missed.

A further option is to use the percentage scaling options in the driver or in the front panel, though these are not particularly recommended.

The following scaling factors should be used:

To scale your ANSI A PostScript ﬁle to... ANSI B ANSI C Arch C ANSI D Arch D Arch E1 ANSI E Arch E Use... 129% 200% 210% 258% 282% 352% 400% 419%

To scale your ISO A4 PostScript ﬁle to... ISO A3 ISO/JIS A2 OS A2 ISO/JIS A1 OS A1 ISO/JIS A0 OS A0 Use... 141% 200% 210% 282% 352% 400% 419%

Color Management PANTONE Colors:

• If you use PANTONE colors from tables within the application, select SWOP as the emulation to use. This method of selecting PANTONE colors is simpler because you do not need to concern yourself with the media or with halftoning. - In Windows 95, go to File → Print → Properties → Device Options → Color Control. - In Windows NT, go to File → Print → Properties → Advanced → Printer Features → Color Management.
