Many times zipping your file and sending it by email is the best option because there is a smaller chance that the file will be corrupted. Also indicate on the printing requisition that you have already sent the files electronically so our Production Planning staff can match the art with the printing order. The layout program will print a separate film for every different color name, even if you meant them to be the same color when printed. Also make sure to specify that the colors you are using are spot colors, not process color. This is accomplished in one of two ways.
Most trapping is done digitally now, often by the graphic designer creating the artwork.
If you don't have software capable of trapping your spot color print jobs, our prepress department will be happy to do it for you. Just let us know that your order requires trapping. The Department of Printing has imagesetting forms available for your convenience. Please include the software program used and whether it's Mac or PC, the file name or names, the fonts used, the ink colors to be used, whether the placed graphics are TIFF or EPS, the job title, and the printing requisition number. You may furnish this information on your printing requisition or an attached sheet.
