They will automatically be created when your file is printed. We recommend that you do not attempt to trap your files but leave this task to our sophisticated trapping software. Trapping is a technique in which adjacent colors slightly overprint along common edges to compensate for potential misregistration that can occur at high press speeds. Understanding where and how to trap elements can be difficult and you run the risk of creating problems rather than solving them if done incorrectly. Do not attempt to do your own imposition.
Imposition is the process of arranging pages in the manner they are printed on the press.
Proper imposition requires knowledge of the press sheet size, the paper's caliper and other binding requirements. We will impose your job using specialized imposition software. It is usually best to create a single file for your entire document. It may be better to break it up into several sections if your publication contains a large number of pages or has special final assembly conditions. Talk to us early if you are unsure of how to set up your file.
