I’m at wits end trying to figure out why I’m getting slurring problems on my SP20. I’m using photopolymer plates from Boxcar on a patmag base. Everything calipers out correctly to .918, including my roller height gauge. I’ve adjusted the rollers and measured them in several places on the bed. I have brand new rollers from Pamarco. I’m using an oil-based mix of trans-white, 072 and Black (cool gray 7). I’m printing a large form (10×15, lots of text) on 110 lb Lettra. I’m just not sure how to proceed to fix this. Help, please!
