OLOR
With PostScript 3, a PostScript job can include calibrated CMYK (or
N :
OTE
CIEBasedDEFG) data. The Rendering Style print option, which normally affects only
RGB data, affects calibrated CMYK data as well. The RGB Source Profile setting does
not affect calibrated CMYK data.

ColorWise print options

The following sections provide detailed explanations of the ColorWise print options and
how these options affect print jobs.

Auto Trapping

Trapping is a technique where the size of objects is modified so that colors printed next to
each other overlap slightly, to prevent white spaces between two colors. These white
spaces, or "halos," can be caused by factors such as misregistration, the physical
properties of the toners, and the stiffness of the media. This illustration shows the same
image with and without trapping.
If you enable the Auto Trapping option, trapping is applied to all the objects in a job.

Black Detection

The Black Detection option allows you to specify whether or not to detect black-and-
white pages before printing your job. To use this option, set Color Mode to Standard Color
or Expert Color.
• : Select Off if your job consists of black-only text pages combined with a significant
Off
number of color pages.
• : Select On if you are printing a predominantly black-and-white job. Black-and-
On
white only pages will print with the proper billing information.
