5. Special Color Requests > 5.5. Adding Trap

Adding Trap

When working with special colors, you have to make sure they will trap properly with one another or with the existing color channels. Trap refers to overlapping areas of color in such a way that if a color becomes misaligned during the printing process, there is sufficient color information between the different colors to prevent a gap through which the white of the paper or another color in the image might poke out where it isn’t suppose to. Your eye can really be drawn to an area that has a poor trap.

Let’s say we were printing the image with the special color text shown in Figure 5-32. Take a look at the difference in the area around the letter S in Figures 5-33, 5-34, 5-35 through 5-36.
