GMG updates ColorServer

GMG has released v5.4 of its ColorServer colour management software which gains a number of new features to automatically deal with problems that previously would have required manual intervention.

Thus, the channel mapping rules have been improved and now support wildcards for spot colours and can automatically process unidentified channels according to preset criteria.

The SmartProfiler module gains a new automatic smoothing of measurement data that corrects inconsistencies in measurement data leading to better profiles. GMG has also improved the total area coverage calculation for better colour matching. In addition, users can now add a flattening option to hot folders to deal with transparencies or overprinting objects in PDFs without defaulting to manual intervention.

A new ‘auto rasterize’ feature also steps in if a user-defined time window is exceeded during the processing of flattening jobs and automatically adjusts the flattening setting to process the files faster.

Jens Bloeck, Product Manager at GMG, says: “We are constantly in close communication with our users. Therefore, we know that efficiency and productivity are more important than ever. With GMG ColorServer 5.4, our customers can sustainably optimize their processes. We have integrated a range of new features that all contribute to increase profitability.”

He adds: “With GMG ColorServer 5.4, we are introducing in-software update notifications. Users no longer need to actively search for new releases.”

GMG has had a busy start to the year, having earlier made improvements to its colour engine, which in turn allowed it to update its OpenColor and ColorProof colour software, which are both aimed mainly at the packaging market.

The basis behind this is updates to the Spectral MX Colour Engine, which can now calculate its MXN proof profiles up to 15 times faster, while improving the quality of the profile and reducing the size of the profile by up to 90 percent. This should lead to better colour matching between proofs and prints.

This has also allowed GMG to add LAB-to-spectral conversion technology to its OpenColor software. This means that OpenColor can now import LAB-based MX4 and ICC characterization data and profiles, which produces a more precise spectral calculation model. This should lead to more accurate predictions of overprinting spot and process colours.

The Spot Color CxF export function can now exchange spectral reference colour values from GMG OpenColor with other production tools and share them throughout the entire supply chain. In addition, GMG technology partners can access these special ink spectral values via the GMG OpenColor interface.

Stefan Zrenner, Head of Sales & Marketing at GMG, explained at the time: “The quality of our proof profiles is crucial for efficient packaging production. The fact that we were able to increase the resolution even further and enhance the precision of these profiles is worth an update in itself. But the performance of the new MX Color Engine, which is up to 15 times faster, is simply sensational. GMG OpenColor and GMG ColorProof are an unbeatable combination.”

Zrenner added: “With this update, GMG OpenColor users benefit from a central platform where all data and profiles for process characterization and spot colours are stored. As a result, the same reference data source can be used for both proofing and color conversions.”
