Copier Calibration

This methodology only works on color laser copiers that come with an inbuilt copy-top scanner for making color copies.

1.	Place Focoltone Calibration Chart over the copier-top scanner and make a color photocopy [Printout 1] of it.
2.	Visually check the colors on Printout 1 and compare against the Focoltone Calibration Chart. You can then tell if your color copier is producing pure and accurate CMYK colors from the color copy.
3.	If it is not, use the calibration predefined in the printer to calibrate the machine e.g. AutoCal, ColorCal etc.
4.	After calibration, make another copy of the Focoltone Calibration Chart [Printout 2].
5.	Compare Printout 2 against the Focoltone Calibration Chart and Printout 1. Check for color improvements and differences.
6.	If you are still not satisfied with Printout 2, you can adjust the tones of colors manually on your copier for it to produce CMYK colors to match those on the Calibration Chart. (Please refer to your copier user manual for machine specific instructions on adjusting the color toners.)
7.	After manual adjustment of your copier's color toner levels, make a third copy of the Calibration Chart again [Printout 3].
8.	Check Printout 3 against the Focoltone Calibration Chart.
9.	Repeat steps 9 - 11 until you are satisfied with your copier colors.
10.	Save the calibration setting you had created. (Please refer to your copier user manual for machine specific instructions.)

However, these adjustments and settings for your color copier will change over time. You will need to check your color copier daily for color consistency. For subsequent adjustments, simply perform the copier's inbuilt calibration tool, e.g. AutoCal or ColorCal, and recall this memory setting.

This approach zeros your color laser copier to its most optimum condition. You will also achieve better and more accurate results when you run Focoltone ICCS after zeroing your copy-top output with the above steps using the Focoltone Calibration Chart.
