The Crystal Preview provides an accurate preview whatever the characteristics of the file, showing you exactly what will be printed, so that you can evaluate the printed colors, and judge for yourself the effect of any problems in the file. However, the Crystal Preview may take longer to generate than the default preview. It performs full color management (see Color management on page 37), and can understand and handle the following PDF features correctly:

Output intent

Transparency

Overprinting

Rendering spot colors with the HP Professional PANTONE Emulation Library

The examples below illustrate two uses of soft proofing, to judge colors and to see what will actually be printed.
