Calibration Check

For Epson SureColor P printers and Epson Stylus Pro x900 and x890 printers with integrated measuring device ILS30, the validity of the printer calibration can easily be verified by printing a GMG Calibration Control Strip. The control strip is automatically measured by the printer in GMG ColorProof.

Some of the features described in the following may not be included in the standard GMG ColorProof version and require an additional license (GMG DotProof, GMG FlexoProof, GMG ProfileEditor, GMG ProofControl Inline, or GMG OpenColor). Please contact your local dealer for details.

The calibration control strip is verified against the target values from the printer calibration file linked to the corresponding calibration set. The result of the calibration check will help you to decide whether the printer needs to be recalibrated or not, thus saving valuable production time, ink, and media for unnecessary recalibrations.

Depending on the results, you can do one of the following:

  1. Results are within your tolerances. No action required.
  2. Additional printer checks such as printing a nozzle pattern and cleaning the print heads. Then, repeat the calibration check.
  3. A printer recalibration is required.

Additional printer checks

In addition to checking the printer calibration, GMG recommends to print a Nozzle Pattern on a regular basis. This can be done manually or automatically with the Automatic Maintenance scheduler in GMG ColorProof (Output > Printers > Automatic Maintenance).

If the lines of the nozzle test pattern cannot be clearly distinguished, the print heads should be cleaned with the Maintenance features supported by the printer in GMG ColorProof (Clean Print Heads, Check and Clean, Power Clean).
