Please check your files for image resolution, bleeds, and fonts/text. Your files must be submitted at the correct size, with bleeds. Please make sure that all text is at least 1/8th inch away from the cut line and that all images and text are at least 300 DPI for rasterized images. Your fonts should be embedded into the file if sending a PDF, otherwise make sure to 'expand' all fonts into a vector object format.
