When submitting a digital file, it needs to be "print ready".  We request that you send us a PDF created at 300dpi (or better), in CMYK (Cyan, Magenta, Yellow & Black) with text/logos a safe distance from the final trim size (at least .25" from edge) and applicable bleed if necessary.  The graphics file you send us should be complete.  If our Graphics Team has to make changes to the file (e.g. resize, adjust color, add bleed, etc.) there will be added charges.
