Color Trapping
Uses an algorithm to compensate for mechanical incorrect registration in the printer. When small black text or
fine black lines are being printed, the printer checks to see if they are being printed on top of a colored
background. If so, rather than remove the color from beneath the black content, the printer leaves the color
around the edge of the text or line. The hole in the colored region is reduced in size, which prevents the
characteristic white gap that is caused by incorrect registration.
Values include Off and numbers 1–5 (the default is 2). Values 1 through 5 indicate the amount of color remaining
beneath the black content. The default is each setting increments by 1/600 of an inch. The more inaccurate the
registration setting, the higher the setting needs to be adjusted. Selecting
Off disables color trapping.
