Chapter 20. Output > When not to apply trapping

When not to apply trapping

Trapping is unnecessary when black type or a black item or frame is on top of a light background color. In this circumstance, the black type will overprint (print on top of) the background color. You can specify a minimum percentage of black to control when and if overprinting will occur (see page 313).

Trapping is also unnecessary if process colors and adjacent or overlapping colors contain a common color component (C, M, Y, or K). Let's say you have a red containing a percentage of magenta that touches a blue area that also contains a small percentage of magenta. The two colors both contain magenta, so trapping is unnecessary.
