Rather suddenly my rollers decided to crap out by not inking the form evenly. I am using photopolymer plates.
Form is not being inked evenly. Ink is heaviest at the beginning of the form (the area the form rollers hit first). Based on the image above, it appears that the rollers are not freely rolling across the top of the form, rather pushing/sliding the ink across. The 2nd example is the worst case scenario – many of the bad impressions made the form look as if it were only half inked.
First, I’ve tried adjusting the roller height and the amount of ink in addition to cleaning all moving parts (nyliners, etc.) – all to no avail. I tried rubber and oil based inks. I even moved the form around on the bed. All with the same result. However, please note that I haven’t tried cleaning the crescent or worm.
I have observed the following behaviors:
 The oscillating roller does not appear to move/roll during inking of the smaller form. With the larger form, it rolls inconsistently – it rolls over some areas and slides across others.
 I get better results when the oscillating roller is in the up position (ie. not touching the form rollers).
 Even with the oscillating roller up, the problem seems to persist with the front form roller.
 I get best results when using only the back form roller (ie. without the oscillating roller or the front form roller in use).
On Another Note
Sort of on the same topic but an entirely different issue, when things are working okay, my rollers are not able to ink the entire bed. It does fine on the first 7″-9″ but the form rollers cannot make contact with the form on the rest of the bed. Does this mean my bed is uneven? If so, how do I fix this?
