Colour management provider GMG has updated its GMG OpenColor software for multi-colour profiles for packaging proofing.
The company says users can create profiles without a test chart. Peter Schoeffler, product manager at GMG, says, “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, GMG 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.”
GMG OpenColor 2.1 offers a measurement capability for custom patches. It enables the measurement of full-tone patches from a print control strip, or solid patches and tint patches on the running printed sheet and to create a profile from the captured spectral data.
It includes 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.
Schoeffler concludes, “Customers can now expect turnaround times reduced by up to 50 per cent, set-up times decreased by up to 30 per cent, characterisation runs reduced or even eliminated, and fewer plates required, meaning less waste and increased profits.”
