'Crop Marks' tell our six Graphic Designers exactly where you want your page cut. Top and Bottom. Left side and Right side. They also tell our bindery workers exactly where to cut your sheet.
Always try to remember to include 'Crop Marks' in your design file. And, if you want a 'Bleed,' include at least a 1/8” extension of your graphic image beyond the 'Crop Mark.' This enables our bindery team to cut on the crop marks, and leave a Bleed.
