Perform a colour validation test

The colour validation test gives an indication of the colour quality for the used media and the linked output profile.

Evaluation tests can have different quality levels based on different tolerance levels for the same metric. You can define custom colour validation tests and a storage location for a detailed CGATS report.

Available colour validation tests

Tools

i1Pro3 spectrophotometer (i1Pro2 also supported).

Before you begin

  1. Calibrate the printer.

    IMPORTANT

    You must always perform a printer calibration before you continue with this procedure.

  2. Calibrate the media family of the media you want to validate.

    IMPORTANT

    You must always perform a media family calibration before you continue with this procedure.

Procedure

  1. Connect the i1Pro3 spectrophotometer to the USB port of the control panel.

  2. Touch [System]  → [Media] .

  3. Select the target media.

  4. Touch [Validate].

  5. Load and assign approximately 10 sheets of the target media in one of the paper trays.

  6. Select a colour validation test.

  7. Touch [OK].

  8. Follow the instructions on the control panel.

Result

After you performed the colour validation, the feedback window shows the results of the performed procedure.

Profile accuracy test

Colour validation test

Description of profile accuracy test

The [Colour validation test] information of the pre-defined profile accuracy test indicates if a media fits the media family. The test also indicates how accurate colours are reproduced on the used media with corresponding output profile.

Description of colour validation test

The [Colour validation test] information of the pre-defined colour validation test indicates if the printed output meets an external colour standard with the current printer condition, used media and corresponding output profile.

Evaluation of profile accuracy test

The test shows the measured value, the tolerance level and the assigned quality level.

  • When the quality level is A the highest quality level is achieved and the colour accuracy is fine.

  • When the quality level is B the quality level is still within specifications and the colour accuracy is fine.

  • When the quality level is not shown than the quality level is not achieved. You are advised to create a new media family for this media.

Evaluation of colour validation test

The test shows the measured value, the tolerance level and the assigned quality level.

  • When the quality level is A the highest quality level is achieved and the colour standard is met.

  • When the quality level is B or lower the quality level is still within specifications and the colour standard is met.

  • When the quality level is not shown than the quality level is not achieved and the colour standard is not met. You are advised to use a media that is more suitable for this standard.

When you want to print a detailed report of the performed colour validation test, touch [OK].

Option to print a detailed report

You can also download a detailed report of the performed colour validation test in the Settings Editor.
