Using Control Strips

Which kind of control strips are supported in GMG ColorProof?

  • Control strips defined by an official print standard, CMYK only: Available for factory-default and custom proof standards, and GMG OpenColor proof standards
  • Control strips defined by an official print standard, CMYK and spot colors: Available for GMG OpenColor proof standards
  • GMG spot color control strips: Dynamically generated from the spot color channels used in the image
  • GMG OpenColor control strips: Dynamically generated from the color channels (GMG OpenColor inks) used in the image
  • GMG Calibration Control Strip: Used for checking if the printer still works in the tolerances or needs to be recalibrated

All four CMYK channels need to be available.

When using a multicolor ICC profile, you can verify the CMYK part (if available) of the profile and single spot colors, but not the overprinting behavior of the spot colors.

What do I need to do?

If you are using a factory-default GMG proof standard, you just need to select an image or job control strip in the job and GMG ColorProof will use the correct target values as defined in the proof standard out of the box.

Likewise, if you are using a GMG OpenColor proof standard, GMG ColorProof will take the target values from the proof profile and you do not need to worry about it.

If you want to use stricter tolerances or verify against a custom print standard, however, you need to take care that appropriate target values and tolerances are defined as explained in the following.
