5-2 PowerColor User Guide
Note: PowerColor calibration is only used with
printed targets, not film-based targets (e.g.
Q60). This calibration method characterizes
output devices, not films.
By characterizing the output device, PowerColor can automatically remove
unwanted contaminants found in inks (a process sometimes referred to as “want-
ed” and “unwanted” calibration). It also allows PowerColor to set the proper
thresholds between the saturated and pastel colors.
The three-color Black patch sets the maximum three-color density. This value is
automatically entered into PowerColor’s setup table and determines the endpoint
of the Grad 3 gradation curve.
Note: The Grad 3 and 4 curves can be viewed
only in Expert mode.
Preparing the Target for Output
PowerColor 16 is a CMYK file in TIFF format. In order to characterize your output
device properly, the file must be processed exactly as a real job, so that all trans-
forms and screens are identical to actual production work.
