Yes, they love to design that way huh? I also have a C&P 8×12, and I have found the only way for full bleed is to print on oversize as you mentioned and cutting after. Or talking them out of a full bleed. 😉 If it’s not a solid bleed and prints to the edge of 3 sides (like an image of some sort), I use handmade registration paper “pins” taped at the bottom, so not as tall as my metal pins & the plate won’t affect them in printing. I’d also love to hear if anyone else has any other suggestions.best,kathryn
