Colour management developer GMG has released a fresh version of its multi-channel profiling software.
The company says GMG OpenColor 2.0.6 has the ability to create and deliver separation and preview profiles to Adobe Photoshop and Packz from Hybrid Software. For existing customers of OpenColor, the latest version offers a new function to calculate separations via rules that can be applied to whole spot colour libraries for calculating the best matches for the separation.
GMG describes OpenColor as a powerful profiling system, which can characterise offset, flexo, and gravure printing processes with 10plus colours of overprinting inks. It does so by applying mathematical models that predict the ink interplay for specific processes and substrates without requiring extensive fingerprint data. GMG says that even without any data, based on pure math, GMG OpenColor has the capability to predict process-specific ink overprints.
Michael Guggemos, head of colour management at MCM Nägele, a GMG customer, says, “With GMG OpenColor we are now able to create GMG DotProof profiles with spot colours for special substrates like foil or metal fast, achieving reliable colour matching results.”
GMG says the update opens up new possibilities for third-party applications, including Adobe Photoshop and Packz. For Adobe Photoshop, with a direct connection to the GMG ColorPlugin integrated in Photoshop, GMG OpenColor 2.0.6 offers a new predictive, on-the-fly profiling for layers and/or selections, from CMYK to any combination of process colours and spot colours. GMG says the new OpenColor Preview function in Photoshop provides a colour-accurate preview with OpenColor prediction technology, so that all changes are immediately visualised.
For Packz, a PDF-based prepress tool suite for professional package and label production, GMG OpenColor can connect to Packz in order to bring dynamically created GMG profiles to another solution. Packz, with GMG OpenColor profiles, can re-separate jobs to reduce or optimise number of plates on press (replacing magenta with a spot colour or separate spot colours and overprints to a seven colour extended colour gamut printing process). It can achieve these re-separation tasks on the fly.
