Greetings Adam! I wanted to ask your advice once more on cutting from a digital output (xerox). Do you find a pot of bounce on registration when printing 20 + sheets on 12 pt or 300 grams matte? Trying to get my skills down on this new cutter, and understand how to set jobs up so that when I go to cut them down I don't destroy the job!! Also what does it mean to back-cut cards? Thanks, kristian
