Set up Command WorkStation for color verification
To verify color accuracy, you must select reference data, and define acceptable dE tolerances. You must also print your jobs with a job label. The job label can consist of one or two control bars, which must be compatible with your measuring device.
Command WorkStation provides default workflow templates that are already set up with the basic settings necessary for verifying color accuracy. If you prefer to set up a custom workflow, make sure to include the following settings.
Do one of the following:
- In Server Manager: On the sidebar, click Printers, and select a printer. In the printer's tree view, select a workflow. On the Verify tab, expand the Control Bars panel.
- In Job Editor: On the Verify tab, expand the Control Bars panel.
- Select a control bar, which can also be a
The following table shows which type of control bar is suitable for each reference:
Type of control bar
Measurement file from remote container
Fogra characterization data
EFI Chart Yes Yes No No IDEAlliance ISO 12647-7 Yes Yes Yes No Ugra Fogra-MediaWedge Yes Yes Yes Yes Dynamic wedge Yes No No No
- On the Verify tab, expand the Verify Control Bar 1 panel. In the tab header bar, select the check box to activate the settings.
- Select Print label after verification automatically (optional).
Some printers with an integrated measuring device can print out a label with the results of the color verification. The label includes all the necessary ISO 12647-7/8-compliant information and is printed regardless of whether the job passes color verification or not. Alternatively, by selecting Print only if verification results passed, you can specify that a label is printed only if all the measured results are within the defined tolerances.
- Select one of the following references:
the reference profile
an MKCheck 10 or MKCheck 11 characterization data set
the measurement file from a remote container
- Under Delta E format, select an L*a*b* tolerance system for measuring color deviation.
- Under Target tolerances preset, define the highest acceptable error margin when verifying the color accuracy of the printout. Do one of the following:
Select a tolerance preset for a recognized standard. You can also modify preset values.
Select a custom tolerance preset.
Define general dE tolerances for a dynamic wedge.
Define custom tolerance limits (house standard) by editing the default values. Custom tolerances provide an easy way to adapt quickly to the latest norms.
Jobs are verified as color accurate only if all color measurements are within the defined dE tolerance limits. In Verifier, you can force jobs to be verified if some dE values are marginally exceeded.
