GMG has launched OpenColor 2.1, multichannel profiling software, to create profiles without test charts. Optical brighteners are now detected automatically. The tool is heavily used in packaging proofing.
GMG OpenColor 2.1 now offers a measurement capability for custom patches. Whereas previously customers would require a specific test chart to create a color 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, such as the GMG ProofMedia OBA series.
