If printer use is heavy, use Splash ColorCal
throughout the day to keep track of color printing
performance and recalibrate as needed. To exit
ColorCal, choose Quit from the File menu.

Accuracy
To verify the accuracy of the calibration, or to
determine the amount of change since the last
calibration, click Verify Accuracy in the ColorCal
main window or click Verify in the dialog box that
appears when calibration is complete. Follow the
same steps used to initially calibrate the printer.

same steps used to initially calibrate the printer.
When the verification process finishes, ColorCal
displays the color performance results. Compare the
Desired Density lines with Measured Density lines
to determine color printing accuracy. The example
below shows that measured output closely matches
desired color performance. Recalibration is not
needed.

The printer may need servicing if the measured curve
does not closely correspond to the target curve during
the verify process immediately after calibrating.
Splash ColorCal cannot operate properly if the copier/
printer is printing unevenly or if the scanner is not
accurately calibrated. To verify whether the scanner is
accurately calibrated, set the active Pass Through
profile to Uncalibrated in ColorCal, then print out
the full area on a page with 40% C, 40% M, and 40%
Y color mix, with Splash Color Correction disabled in
the Splash print driver. Examine the printed page to
see if the output is an even gray with little variation.
Significant variation indicates that the printer needs to
be serviced. If the printer needs servicing, contact
your printer manufacturer representative.

AutoGray
AutoGray is a secondary calibration performed to
improve the gray balance of the calibrated printer.
AutoGray is a Splash menu option similar to Calibrate
Scanner that prints and then scans a target and uses
the information from the scan to automatically adjust
the calibrated profile to improve gray
balance.AutoGray can be run without preliminary
configuration.
