GMG enables multi-colour profiling without test charts

GMG has introduced OpenColor 2.1, a new release of its award-winning multichannel profiling software. OpenColor, which has proved itself to be the most powerful tool on the market for multicolour profiles for packaging proofing, now offers a measurement capability for custom patches. Whereas previously customers would require a specific test chart to create a colour profile, GMG OpenColor 2.1 enables the measurement of full-tone patches from a print control strip, or even solid patches and tint patches on the running printed sheet and to create a profile from the captured spectral data, something no other profiling tool can achieve.

The second key development in GMG OpenColor 2.1 is the inclusion of a detection tool for optical brighteners, which overcomes the issue customers face when they want to create a profile for a substrate and find that the proof doesn’t match the print as it hasn’t taken account of the optical brighteners in the printing material. However, when a customer measures a test chart, mini-strip or patches using GMG OpenColor 2.1, the software identifies optical brighteners in the substrate and recommends the correct measuring mode settings and the use of a proofing paper that also contains optical brighteners, e.g. GMG ProofMedia OBA series.
