But, it must be a media problem
since I can print the same negative on paper with no sign of banding.
For gum you might want to consider printing on paper for your
negatives.
Interesting. It makes sense (in a weird sort of way) that the banding
doesn't occur on paper, since it's not a problem you normally see in a
digital print.
Maybe that's the answer to the venetian blinds though...paper negatives! :)
I'm reluctant to conclude it's a media problem, although it's obviously
affected by the media. I'm curious if anyone's had these banding problems
with different OHP substrates (other than Pictorico). Anyone?
