Imation™ Rainbow™Color Proofing System FAQs

Q: When a PostScript error has occurred, how can the problem best be isolated?

The Rainbow™ software has a small PostScript™ file in a folder named Imation Rainbow™ Test. Proofing this file usually will indicate that the Rainbow™ software and Macintosh™ computer are okay.
Occasionally, PostScript errors occur when the Rainbow™ system runs out of free hard disk space while processing a file. Ensuring that there is plenty of free space and setting the Postscript Scratch Space to 300MB sometimes helps.
If there are TIFF and EPS images in the file, a PostScript file can be made omitting them to see if one of those images is causing problems. If so, the images can be added back a few at a time until the problem image is identified.
Substituting fonts and creating a PostScript file will help determine if one of the fonts is causing a problem. Again, add the fonts back systematically.
There are sometimes unexplained PostScript errors that can be resolved by saving the document as an EPS and bringing it into a new QuarkXPress™ page and proofing the QuarkXPress file.
