How you prepare an image for a page-layout program depends upon the file formats the program recognizes:
Adobe InDesign 2.0 and later can place Photoshop PSD files. You do not need to save or export your Photoshop image to a different file format. Transparent areas are displayed and printed as expected.
Most other page-layout programs require you to save the image as a TIFF or EPS file. However, if the image contains fully transparent areas, you must first define those areas using a clipping path. Check the documentation for your page-layout program to determine the best format for importing Photoshop images.
If the page-layout program cannot place Photoshop PSD files, follow these steps:
TIFF Options dialog box: set Image Compression to None.
EPS Options dialog box (Windows): set Preview to TIFF (8 bits/pixel) and Encoding to ASCII85.
EPS Options dialog box (Mac OS): set Preview to Mac (8 bits/pixel) and Encoding to ASCII85.
If
the layout program displays transparent areas as white, try printing
the document. Some layout programs do not display clipping paths
properly but print them as expected.
