I formatted my 12 X 12 book PDF with a bleed of only 0.125"
I made a mistake by following the wrong advice on Lulu.com's downloadable template instructions, and I formatted my 12 X 12 hardcover photobook PDF with a bleed of only 0.125" (12.125 x 12.125"). Will the print department automatically re-size my PDF to have a bleed of 0.25, or even resize the PDF to 12.25 X 12.25"? Please tell me I didn't throw away over $120 because of incorrect instructions. I ordered two book proofs.
