    CDOT Shaded Color and Grayscale Printing Reference File Management

    CDOT Shaded Color and Grayscale Printing This document guides you through the set-up and printing process for shaded color and grayscale Sheet Files. This workflow may be used any time the user wants to highlight specific areas for things such as phasing plans, public meetings, ROW exhibits, etc. Please note that the use of raster images (jpg, bmp, tif, ets.) will dramatically increase the processing time during printing. Reference File Management Adjustments must be made to some of the reference file settings in order to achieve the desired print quality. The settings that need to be changed are the Slot Numbers and the Update Sequence. Slot Numbers are unique identifiers assigned to reference files and can be called out individually or in groups within a pen table for special processing during printing. The Update Sequence determines the order in which files are refreshed on the screen and printed on paper. Reference file Slot Number Categories: 0 = Sheet File (black)(this is the active dgn file.) 1-99 = Proposed Primary Discipline (Black) 100-199 = Existing Topo (light gray) 200-299 = Proposed Other Discipline (dark gray) 300-399 = Color Shaded Areas Note: All data placed in the Sheet File will be printed black. Items to be printed in color should be in their own file. Create a new file using the standard CDOT seed files and reference design elements to create color areas. If printing to a black and white printer all colors will be printed grayscale. Files can still be printed using the default printer drivers and pen tables, however shaded areas will lose their transparency and may print black depending on their level.
  • The Art of Digital Black & White by Jeff Schewe There's Just Something

    The Art of Digital Black & White by Jeff Schewe There's Just Something

    The Art of Digital Black & White By Jeff Schewe There’s just something magical about watching an image develop on a piece of photo paper in the developer tray…to see the paper go from being just a blank white piece of paper to becoming a photograph is what many photographers think of when they think of Black & White photography. That process of watching the image develop is what got me hooked on photography over 30 years ago and Black & White is where my heart really lives even though I’ve done more color work professionally. I used to have the brown stains on my fingers like any good darkroom tech, but commercially, I turned toward color photography. Later, when going digital, I basically gave up being able to ever achieve what used to be commonplace from the darkroom–until just recently. At about the same time Kodak announced it was going to stop making Black & White photo paper, Epson announced their new line of digital ink jet printers and a new ink, Ultrachrome K3 (3 Blacks- hence the K3), that has given me hope of returning to darkroom quality prints but with a digital printer instead of working in a smelly darkroom environment. Combine the new printers with the power of digital image processing in Adobe Photoshop and the capabilities of recent digital cameras and I think you’ll see a strong trend towards photographers going digital to get the best Black & White prints possible. Making the optimal Black & White print digitally is not simply a click of the shutter and push button printing.

  • Grayscale Vs. Monochrome Scanning

    Grayscale Vs. Monochrome Scanning

    13615 NE 126th Place #450 Kirkland, WA 98034 USA Website:www.pimage.com Grayscale vs. Monochrome Scanning This document is intended to discuss why it is so important to scan microfilm and microfiche in grayscale and to show the limitations of monochrome scanning. The best analogy for the limitations of monochrome scanning is if you have every tried to photocopy your driver licenses. The picture can go completely black. This is because the copier can only reproduce full black or full white and not gray levels. If you place the copier in photo mode it is able to reproduce shades of gray. Grayscale scanning is analogous to the photo modes setting on your copier. The types of items on microfilm that are difficult to reproduce in monochrome are pencil on a blue form, light signatures, date stamps and embossing. In grayscale these items have a much higher probability to reproduce in the scanned version. Certainly there are instances where filming errors exist and the film is almost pure black or pure white. This can happen if the door to the room was opened during filming, if the canister had light intrusion prior to developing or if the chemicals or temperature were off on the developer. If these are identified the vendor can make a lamp adjustment in these sections of film or if they are frequent and the vendor has the proper cameras, they can scan at a higher bit depth. We have the ability to scan at bit depths higher than 8 bit gray up to 12 bits. 8 bit supports 256 levels of gray, 10bit supports 1024 levels and 12 bit 4096 levels.

It has been prepared mainly for architects and engineers, but may also be relevant for conservator-restorers or archaeologists. It aims to: - offer an overview of each problem area combined with laboratory practicals and case studies; - describe some of the most widely used practices and illustrate the various approaches to the analysis of materials and their deterioration; - facilitate interdisciplinary teamwork among scientists and other professionals involved in the conservation process. The Handbook has evolved from lecture and laboratory handouts that have been developed for the ICCROM training programmes. It has been devised within the framework of the current courses, principally the International Refresher Course on Conservation of Architectural Heritage and Historic Structures (ARC). The general layout of each volume is as follows: introductory information, explanations of scientific termi- nology, the most common problems met, types of analysis, laboratory tests, case studies and bibliography. The concept behind the Handbook is modular and it has been purposely structured as a series of independent volumes to allow: - authors to periodically update the

    SCANNING & HALFTONES Ethics It is strongly recommend that you observe the rights of the original artist or publisher of the images you scan. If you plan to use a previously published image, contact the artist or publisher for information on obtaining permission. Scanning an Image Scanning converts a continuous tone image into a bitmap. Original photographic prints and photographic transparencies (slides) are continuous tone. The scanning process captures picture data as pixels. Think of a pixel as one tile in a mosaic. Bitmapped images Three primary pieces of information are relevant to all bitmapped images. 1. Dimensions Example: 2" x 2" 2. Color Mode Example: 256 level grayscale scan 3. Resolution Example: 300 ppi Basic Steps of Scanning 1. Place image on scanner bed Scanning & Halftones 2. Preview the image – click Preview 3. Select area to be scanned – drag a selection rectangle 4. Determine scan resolution (dpi or ppi) 5. Determine mode or pixel depth (grayscale, color, line art) 6. Scale selected area to desired dimensions (% of original) 7. Scan Resolution Resolution is the amount of something. something amount amount over physical distance fabric the number of stitches in fabric the number of stitches per inch in a needlepoint film the amount of grain in film the number of grains in a micro meter in film digital image the number of pixels the number of pixels per inch in a digital image Resolution is a unit of measure: Input Resolution the number of pixels per inch (ppi) of a scanned image or an image captured with a digital camera On Screen Resolution the number of pixels per inch displayed on your computer monitor (ppi or dpi) Output Resolution the number of dots per inch (dpi) printed by the printer (laser printer, ink jet printer, imagesetter) dpi or ppi refer to square pixels per inch of a bitmap file.
