Note:
Although Adobe InCopy does not include color-management options, these import options are relevant when the
images you place in InCopy are transferred to InDesign.
When you place a PSD, TIFF, GIF, JPEG, or BMP file and select Show Import Options in the Place dialog box, you’ll
see a dialog box containing these options:
Apply Photoshop Clipping Path
If this option isn’t available, the image wasn’t saved with a clipping path, or the file
format doesn’t support clipping paths. If the bitmap image doesn’t have a clipping path, you can create one in
InDesign.
Alpha channel
Select an alpha channel to import the area of the image saved as an alpha channel in Photoshop. InCopy
uses the alpha channel to create a transparent mask on the image. This option is available only for images that contain
at least one alpha channel.
Image imported without clipping path (left) and with clipping path (right)
Click the Color tab to view the following options:
Profile
If Use Document Default is selected, leave this option unchanged. Otherwise, choose a color source profile that
matches the gamut of the device or software used to create the graphic. This profile enables InDesign to properly
translate its color to the gamut of the output device.
Rendering Intent
Choose a method for scaling the color range of the graphic to the color range of the output device.
Typically, you’ll choose Perceptual (Images) because it accurately represents colors in photographs. The Saturation
(Graphics), Relative Colorimetric, and Absolute Colorimetric options are better for areas of solid color; they don’t
