Verifying Spot Colors

If you want to know how well spot colors printed in an image match the reference values, you can add a spot color control strip to your image in GMG ColorProof (> Image Control Strips).

With an integrated ILS30 measuring device and a GMG ProofControl Inline license, all patches are automatically measured and a verification label is printed on the proof.

GMG OpenColor spot colors are validated by comparing the measured values against the Lab target values from the multicolor profile. In both cases, the Delta E values are printed in a label, showing you which spot colors can be reproduced by your printer-medium combination and which colors are out-of-gamut. You can optionally define tolerances for a pass/fail verification of the spot colors.
