GMG enables multi-colour profiling without test charts

Packaging Solutions

GMG has launched OpenColor 2.1, a new release of its multichannel profiling software for packaging proofing.

Profiles can now be created without a test chart OpenColor 2.1 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 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 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, eg GMG ProofMedia OBA series.

Product manager Peter Schoeffler commented, ‘GMG OpenColor has become the indispensable profiling solution for any package printer or company printing spot colours on materials such as ceramics, tissue or beverage cans. For colour accurate proofing of spot colour overprints, OpenColor is the only available solution. Customers are now able to precisely predict spot colours and the interaction between them. It even allows them to create a profile from any measurement captured from a running print job.’

Customers can now expect turnaround times reduced by up to 50%, set up times decreased by up to 30%, characterisation runs reduced or even eliminated, and fewer plates required, meaning less waste and increased profits.
