Yes, please make sure your catalog files are prepared with a 0.125" bleed. For your convenience, we offer downloadable catalog templates that are clearly marked with the safe zone, trim line, and bleed line. All crucial elements (copy, photos, graphics, logos, etc.) should be within the safe zone of the template, so they are not cut off. The trim line shows where the pages will be cut, and the bleed refers to the part that will be trimmed off. If you are incorporating background images, please make sure they extend all the way to the bleed line, so that the backgrounds extend to the edge of the pages.
