Printing Services Questions:
If a transparency issue occurs in printing, the good news is that it can be fixed before you save your file. See to it that you refrain from using glows, shadows, or other transparency images directly above a spot color. Before sending the file for printing, never forget to alter the spot color to CMYK and flatten it. Overprinting is the process in which one prints an image over an area that’s already been printed. Overprinting can be closely identified with print trapping, a method of adjusting colors so that misregistration isn’t an issue in printing.
Misregistration can cause gaps that are unintended between inks, due to the fact that it’s unrealistic to expect accurate registration on all your prints every time. There are two different types of print trapping, a spread and a choke. A spread occurs when an object that’s light overlaps a background that’s dark, allowing it to widen into the background. On the other hand, a choke happens when a background that’s light overlaps an object that’s dark, allowing the darker object to fall inside the background to the point where the object appears to be squeezed or reduced in size.
Print trapping can be helpful with overprinting issues because it serves as a printing solution for misregistration by intensifying one object so it can overlap another object that’s a different color. Overprint won’t destroy your file if you be sure to turn all overprint objects off before you send your files to J.M. Field Marketing for printing. Setting objects to overprint can create unexpected and unwanted results, so try to browse beforehand for any issues before submitting anything to print.
