We print A2 and A6 cards on our 8×12 C&P and have not cut our base. We merely cut the paper after printing instead of before. It’s a little more labor intensive but, as I understand it, most people with platen presses do it this way. Also, it doesn’t limit us if we print something else like a larger print. We hope to graduate to a windmill soon in which case we can cut the paper first. Good luck!
