Calibrating PowerColor Press
CAUTION: PowerColor Press should be set up
and calibrated only using the procedures in this
section. Do not make any adjustments in the
CMYK Setup window.
Understanding Calibration
PowerColor incorporates a user-friendly method of calibrating the CMYK
Separator for specific output devices, such as inkjet printers, conventional proof
printers, and printing presses. The software includes a file called PowerColor 16,
which contains patches for saturated and pastel colors, as well as a three-color
and four-color Black patch (see Figure 5–1). The markers A, B, and C outside the
color patches identify the orientation of the target and the location of the patches.
