Without Test Chart—Measuring Custom Patches

You might encounter having difficulties to get characterization data from the printing company and might simply be left with the print product itself. For such cases, GMG OpenColor offers you the possibility to measure colors from the printed sheet, i. e. from the design itself (provided you know the color separation of the measured tone) and from standard process control strips included on the printing form.

This method requires almost no effort and no additional resources such as print cylinders. Profile creation relies to a high degree on the GMG OpenColor Prediction Engine.

Print control strip example.

Measuring these 12 example patches is all you would need to create a proof profile for a 5c printing process. You could measure the four numbered colors to characterize Pantone 301c:

  1. Medium: Paper tint
  2. Solid: PANTONE 301 (100%)
  3. Tint: PANTONE 301 (80%)
  4. Tint: PANTONE 301 (20%)
