[kathryn]

Hi there, I'm having a problem and I hope someone can help. We just got a couple of new scanners and this is our first time using SilverFast. Here's a summary of what's going on:

Scanning at:
-332dpi
-QFactor 2.5
-Screen: 133
-cmyk
-100%
-we are scanning a finished book cover

when descreen 133 is selected, image becomes blurry. without descreen
image is crisp but moire pattern shows. can't get a clear descreened
scan. have same problem on 2 macs runnng same equipment and software. tried
USB with same results. have used Agfa and Microtek scanners in the past
and never had this problem. Epson scanner is only a week old.
