I have not made a layout for printing before. The printing company requests a CMYK PDF which is scaled to the actual print size, with a 0.125" white margin on all sides, which they call a "bleed." They also want crop marks, showing where the image must be trimmed. I have found this difficult to accomplish with Acrobat 11 Pro.
there are three files: One is 8.5 x 6 inches, which is how the finished product should appear. It will be folded in half. Another file is 8.75 x 6.25 inches, consisting of the finished product surrounded by the 0.125" bleed, or white margin. However, I haven't succeeded in placing trim marks properly. The third file has trim marks, but when I printed it to a file, most of the image information was lost, and the size reverted to 11 x 8,5".
I'd appreciate instructions on how to place trim marks on the 8.75 x 6.25 file, such that the white margin is maintained, the page size is maintained, and the trim marks indicate that the finished product is to be cropped so as to eliminate the marginal bleed area. Also, please verify that the PDF files in that folder are CMYK.
