alpha masks in QuarkXPress, you must first create an alpha mask in an image-editing
application such as Adobe Photoshop. You can then use the alpha mask in QuarkXPress.
The alpha mask on the flames allows the text in the background to show through.
To work with alpha masks in QuarkXPress, you'll need to save them with the picture
in a format that supports alpha channels.
To apply an alpha mask to the selected picture, choose an alpha channel from the
Measurements palette's Mask drop-down menu. On Windows, you can also apply an
alpha mask with the Channel drop-down menu in the Picture tab of the Modify
dialog box (Item menu).
By default, this drop-down menu is set to Composite, which preserves the image's
overall transparency.
Working with PSD pictures
You can import native, unflattened picture files from Adobe Photoshop directly into
QuarkXPress with PSD Import functionality. Once files are imported, you can
manipulate any layers, channels, and paths saved with the Photoshop (PSD) files. This
integration between Photoshop and QuarkXPress streamlines your workflow by allowing
you to skip flattening; saves hard disk space by enabling you to work with native files;
and enhances your creative possibilities by providing access to layers, channels, and
paths.
With PSD Import, use File > Import to import a PSD file into a selected QuarkXPress
picture box.
To work with layers, channels, and paths in the image, choose Window > Advanced
Image Control. You can use the Advanced Image Control palette to blend layers,
work with color channels, and select paths.
