To hide all but one layer, Option+click/Alt+click the eye icon .
If changing the blending and opacity of layers produces undesirable results, you can
revert the layers to their original state in the imported PSD file with the Revert Layer
or Revert All Layers options in the Advanced Image Control palette menu.
Modifying PSD layer opacity
A field on the Layers pane let you control the transparency of pixels on a selected
layer. You can specify a transparency from 0% (transparent) to 100% (opaque).
Working with layer masks
If layer masks are saved with PSD files, you can enable and disable the masks in the
Layers pane of the Advanced Image Control palette by Shift-clicking the thumbnail
preview of the layer mask.
Working with PSD channels
Photoshop channels store color information about images. By default, grayscale and
indexed color images have one channel, RGB images have three channels, and CMYK
images have four channels. These are referred to collectively as the default channels.
You can use the Channels pane of the Advanced Image Control palette to show and
hide all channels, to change the color and ink solidity of a selected spot-color channel
or alpha channel, and to assign spot colors to selected indexed colors. For example,
you might assign special effects such as varnishes, embossing, and die cuts to channels.
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,
