What is trap and should I do that before I send the file to you?
Trapping digital files is the process of compensating for misregistration on the printing press by printing small areas of overlapping color where objects meet. Presses aren't perfect. They run at incredibly fast speeds. Sometimes the paper or the plates applying the ink may shift. It might be a tiny, tiny little shift -- but it can throw off your design enough to be noticeable. For example, a white gap may appear between a green letter that is supposed to be touching a blue box. When this happens your color is out of register -- things just don't align properly. We prefer to do the trapping for you. If there are any special trapping concerns your printer may have, please let us know about them when you send in your job.
