I'm using scanimage to make the most accurate scans I can and I have a few questions. Many thanks to anyone who can help with any of these issues.
ICC I've posted on this subject before and Allan told me I should scan a color target along with my scans so I can apply an ICC profile. Can I order a color target online? Is there a particularly one to get? white marks I'm getting vertical line artifacts whenever I scan the back of a CD. I've attached an example of this. Allan told me I should calibrate the scanner, but I've checked the manual, searched the unit's front panel, Googled, and called Epson but there doesn't seem to be a calibration procedure. Does anyone know how to set up a "white marks" target to eliminate the artifacts? gamma table I saw mention of gamma tables in the scanimage man page. Is it necessary to use a gamma table for accurate scans? scaling artifacts When I started scanning at 600 resolution instead of 300, I noticed patterned artifacts would appear on the images if they were zoomed to certain levels. For example, the artifacts appear at 50% zoom level in both gimp and gthumb but not at 25% or 100%. It seems like this might have to do with the tiny dots that make up the printed images I'm scanning? Can I prevent it from happening? - Grant -------------- next part -------------- A non-text attachment was scrubbed...
