For those of you that use Patmag bases, what do you do to keep your steel-backed plates from moving? I have a pretty large solid – about 15″ x 4″ – that I’m running and I discovered, upon running the second color, that the plate had continually moved throughout the run. Makes registration a damn pain, that’s for sure.
Anyone try spray mount? I know that would mess up minute registration adjustments, but I need something to keep the stupid thing from moving, even minutely.
I put some scotch tape on just to see what would happen and you can see how it’s shifting and torquing. This isn’t even the big plate (and ignore the messy plate; I was hand-rolling).
