I’m printing a very large plate of a linear illustration. The poster size is 18×24 and the plate is almost that size. I’m using my SP-20. The problem I’m having is, right in the middle of the form, I’m not getting solid ink coverage. It’s almost exactly in the center. My rollers are only 4 years old, although I suppose it’s possible they have shrunk a little. To get the middle to ink properly, I’ve had to really lower the rollers. The problem with that is then the ink coverage is so heavy on all 4 sides that it looks like crap and is slurring off and building up on the edges. Not good. I’m not sure what to do. The illustration is all connected lines, so I can’t pull out a piece and print in a second pass.
To make matters more fun, I’m running a 3-color split fountain. I was thinking of running the colors separately. Would they blend properly? The issue would still remain with the very center of the poster, as the middle color is very heavy on the leading and end of the sheet, but too light in the very middle. I just don’t know how to compensate for this. It doesn’t seem as if makeready on the packing would solve it as impression is fine.
I should also add that I can’t just pull up the plate and add some paper behind that section. It’s mounted on a wood board. If I pull it up, tons of little pieces of the wood come with it and that’d be it for the plate.
