I’m having some issues with a print I’m working on today. It’s a long form (photopolymer) – approx 17” – that I’m running vertically.
I’m using photopolymer on a solid wood base that’s shimmed with chipboard up to type high. Printing on Lettra 110 with black ink. The initial couple of lines are very heavy, inkwise as well as impression, but then within an inch or two the ink becomes more consistent, although not dark enough. I tried rotating the plate and running it horizontal, but I just got very hard impression and overinking on the leading edges as well as the opposite edge of the type. I’ve adjusted my rollers to type high as well. I have a rider roller for the press, but I’ve never used it and am not sure how to attach it, in case that might help the situation.
