Hi Alicia,
In the past, I have had to print solids, and the folks are right—it is difficult at best to get a nice, rich solid. A couple of things I did to help included the following: if you have them, run the idler rollers on your form rollers to maximize your ink supply. I would (by gentle stages) thin the ink out, and as a last resort, I’d under-print a 50% tint screen of the solid, then print the solid on top once it had dried. Oh, and adding a bit of gloss varnish to the ink sometimes makes a solid appear “deeper” than otherwise.
Let’s see–if you want to have some fun with it, get full-color seps and print it as a four-color process piece. If you are like me, it will be fun even as it drives you a bit crazy……
