Printing problem with 3800

lcooper · Sep 7, 2010

I have been printing on inkpress clear film and when I make digital negatives, I see a pattern of very small squares on the print. These only show up on light areas of the print and are small, but they annoy the hell out of me. Nozzle checks do not seem to make a difference. Any ideas?

Post a picture. Little squares are a new wrinkle.

Could these be compression artifacts from JPG, or pixelization from a too-large up-res?

Change one thing at a time until it goes away: substrate, the file you are printing, the source of the file, the print engine - Epson, QTR, etc., driver settings, black ink, paper path, whatever you can think of. Best guess is it's something in the file.

Coopah - Did you figure this out? I just came across what may be the same thing. The squares appear when flattening a high-res file. This file is at 4000 dpi. and several hundred megabytes. When I changed the resolution to 360 dpi at roughly the same file size before flattening I didn't get the squares when I flattened.

These are initial observations - I've not done a careful investigation. Anyone else seen this?

Best, Ben
