2. Inks remapping in Channel Mapping

With Channel Mapping, you can remap inks in CMYK images that are either embedded or placed in your Illustrator documents. In the case of placed images, Channel Mapping doesn’t alter the original (linked) image, but the embedded version in your document, making the changes non-destructive. Channel Mapping also remembers the original image’s name after you edited it. Channel Mapping can remap the inks of all commonly used images formats (TIFF, JPEG, PSD, Photoshop DCS, Photoshop EPS, PNG, GIF...), and remap several images that have the same characteristics at once. Channel Mapping also allows you to set your images to overprint other objects in your document, or to use ink tints in your images.

3. Getting Started

1. Place a CMYK image in your Illustrator Document.

2. Go to Window > Esko > Channel Mapping. This opens the Channel Mapping palette. It shows the inks used in your image in the Inks column, and allows you to map them to other inks using the Map to column.

3. To remap an ink, click on its name in the Map to column and select another ink in the drop- down list.

6 Channel Mapping for Adobe Illustrator 3

Note: The drop-down list only contains inks that are defined in your document.

4. Click the Apply button at the bottom of the palette. You can see that the ink has been remapped in your image.

Note: If you want to undo the remapping, use Command + Z.

7 4 Channel Mapping for Adobe Illustrator

4. The Channel Mapping Palette

You can open the Channel Mapping palette from Window > Esko > Channel Mapping. When you select a CMYK image, this palette shows: • the Name of the original linked image,

• if this image is in Overprint or not,

• the inks used in your image in the Inks column,

• the inks those inks are currently mapped to in the Map to column,

• the tint percentage used for each ink in the Tint column.

Attention: To see information in the Channel Mapping palette, you must select either only one image, or only images with similar characteristics (for details, see Remapping Inks in Several Images on page 12). If you can’t see information in the palette after selecting an image, it may be because you accidentally selected other objects too. To have a better control over which image(s) you select, you can select it/them from Illustrator’s Layers palette or use the Go To Link button in Illustrator’s Links palette.

5. Remapping Inks

5.1 Remapping an Ink

1. Select the CMYK image you want to remap in your Illustrator Document.

To make sure you select only the image, select it from Illustrator’s Layers palette or use the Go To Link button in Illustrator’s Links palette. 2. Go to Window > Esko > Channel Mapping. This opens the Channel Mapping palette. It shows the inks used in your image in the Inks column, and allows you to map them to other inks using the Map to column.

3. To remap an ink, click on its name in the Map to column and select another ink in the drop- down list.

9 5 Channel Mapping for Adobe Illustrator

You can remap an ink to any other ink that:

• is defined in your document (to see all the inks defined in your document, go to Window > Esko > Ink Manager),

• is defined in the swatch list as a spot color (you should see a dot in the swatch’s lower

right corner ).

Note: If you want to remap one of your inks to an ink that is not defined in your document, see Creating a New Ink for Remapping on page 11.

4. Click the Apply button at the bottom of the palette or click Apply in the fly-out menu to apply the remapping to your image. You can see that the ink has been remapped in your image.

10 Channel Mapping for Adobe Illustrator 5

Note: To undo the last remapping, use Command + Z. To undo all remappings and get back to the original image, click Revert at the bottom of the palette or Reset To Original in the fly-out menu.

5.2 Creating a New Ink for Remapping

If your document doesn’t contain the ink you want to remap one of your inks to, you can create it in Illustrator.

1. With your document open, go to Illustrator’s Swatches palette. 2. Define a new spot color swatch as you would normally do in Illustrator. 3. Use this swatch to create an object in your document. 4. Save your document. 5. Map your ink to this new ink in the Channel Mapping palette (as described in Remapping an Ink on page 9). 6. Delete the object you created in the new swatch (in step 3) if necessary, and save your document again.

5.3 Removing an Ink from an Image

1. Select your image. 2. In the Channel Mapping palette, click on the ink you want to remove in the Map to column, and select None in the drop-down list.

3. Click Apply.

6. Remapping Inks in Several Images

You can use Channel Mapping to remap inks in several images at once if those images: • are all embedded, or all linked; • are either not mapped, or all mapped the same way (with the same source channels and the same target channels); • all have the same Overprint state (either overprinting or not overprinting).

1. Select the images you want to map either using Illustrator’s Selection tool or from the Layers or the Links palette. The Channel Mapping palette displays the inks as it normally would for one image, and the names of the selected images.

2. Remap your inks as explained in Remapping an Ink on page 9. When you click Apply, it applies your changes to all selected images.

7. Remapping Images with Masks

7.1 Embedded Images

With embedded images, you can remap any ink to a mask, to use it as an alpha channel, whether the original image had a mask or not. If your embedded image has a mask, you can remove it by remapping it None or to an ink.

Note: You can only have one ink mapped as a mask in your image.

• To remap an ink to a mask: a) Select your image. To make sure you select only the image, select it from Illustrator’s Layers palette or use the Go To Link button in Illustrator’s Links palette. b) In the Channel Mapping palette, remap your chosen ink to Mask.

c) Click Apply.

• To remap a mask to an ink / remove it completely: a) Select your image. b) In the Channel Mapping palette, remap your mask to your chosen ink / to None.

13 7 Channel Mapping for Adobe Illustrator

c) Click Apply.

7.2 Linked Images

If your linked image has a mask, you can remove it and restore it. You cannot map inks to a mask for linked images. If your linked image doesn’t have a mask, you cannot create one.

• To remove the mask from the image: a) Select your image. b) In the Channel Mapping palette, remap the mask to None.

c) Click Apply.

14 Channel Mapping for Adobe Illustrator 7

• To restore the mask, map it back to Mask.

7.2.1 Alpha Channel Special Considerations

When a linked image has process (CMYK) colors, spot colors, and a mask, Illustrator’s default behavior is to apply the mask only to the CMYK channels, and put the spot color channels in Multiply blending and unmasked. Channel Mapping preserves this behavior.

8. Making an Image Overprint

You can use Channel Mapping to set your images to overprint.

• To do this, enable the Overprint checkbox at the bottom of the Channel Mapping palette. You don’t need to click Apply.

9. Using Ink Tints

With Channel Mapping, you can use Ink Tints in your image. To change the tint of an ink in your image, do the following.

1. Go to the Tint column in the Channel Mapping palette and edit the tint percentage.

2. Click Apply.
