Okay, so it a simple 2 color business cards. A newbie could do this is an hour. But Nooooo. Using polymer plates, we ran the black, then matched up the red plate PERFECTLY on the Boxcar Press base. And guess what? Nothing lines up. So we adjust the plate on the base and run another test. Not consistent and worse than before. After pulling what is left of my hair out, I notice that the carriage “racks” a little bit left and right while it is in the middle of the bed. I never noticed this before so I think this “racking motion” is causing the misalignment of the plates or the “inconsistency”. How can I determine if this is it and if it is “racking” how do I fix it?
