Showing and hiding channels
Visible channels in imported PSD files display on screen and can be printed;
channels that are hidden do not display on screen and cannot be printed. The
process to show and hide channels is the same as for layers.
Clicking the composite channel displays all the default channels, such as CMYK
or RGB.
Modifying channel color and solidity
You can use the Advanced Image Control palette to change the color, shade, and
ink solidity of any spot color, mask, or alpha channel you created in Photoshop.
You can assign spot colors to channels that overprint composite images, and
you can specify solidity for displaying channels on-screen and printing color
composites.
Channels specified as mask channels in Photoshop are imported differently
than channels specified as spot colors. In Photoshop, mask channels are
assigned an opacity setting, while spot channels are assigned a solidity setting.
Since PSD Import supports ink solidity, mask channels are imported with a 0%
ink solidity. To see mask channels in imported PSDs, you need to manually turn
on the mask channels in the Channels tab of the Advanced Image Control
palette. Spot-color channels, on the other hand, retain the solidity setting saved
in the PSD file and are mapped to QuarkXPress colors by default.
Use the Channel Options dialog box to modify the color, shade, or ink solidity of
pixels in a spot-color or alpha channel. To display the Channel Options dialog
box, simply double-click a channel in the Channels pane of the Advanced Image
Control palette (Window menu).
Working with indexed color channels
By default, when you print color separations from QuarkXPress using PSD
Import, the colors in indexed color images separate to CMYK. You can override
this by creating a spot color or multi-ink color (Edit > Colors) and assigning that
color to the selected indexed colors in the image. Advanced Image Control also
allows you to create spot colors from colors in the indexed color image. Indexed
colors that you do not modify will still separate to CMYK.
Working with PSD paths
You can also use PSD Import to choose among embedded paths for specifying
clipping and runaround. The Paths pane in the Advanced Image Control palette
provides convenient access to the clipping-path and text-runaround functions
in QuarkXPress
