Accurate Colors in Print & Proof:
GMG OpenColor

Specifically designed to meet the needs of the packaging industry, GMG OpenColor makes sure CMYK and spot colors print exactly the way you want them to

GMG's patented OpenColor technology is unique. It enables accurate proof simulation of the overprinting effects of spot colors using special multichannel profiles. The spectral data calculation includes printing technologies, media types and printing order and its results are so reliable that profile iterations are no longer necessary.

A complete printing press simulator - even if only CMYK is printed

Do you need to change the color sequence in an order? Has the density changed, or the substrate? GMG OpenColor immediately calculates a new profile. Instead of printing on the machine again and again, the result of changed conditions can now be predicted accurately and with minimal expenditure.

Continuous or halftone proof? OpenColor means open possibilities

Apart from checking the color accuracy, GMG OpenColor also makes sure moiré, incorrect trapping settings and other defects will not become the showstopper of the upcoming production run. Easily create halftone profiles for the colors you need, be it CMYK or spot colors, and print high-end halftone proofs in GMG DotProof and FlexoProof that predict the press result with dot-for-dot precision, including the screen rulings, angles, dot shape and dot gain.

„With GMG OpenColor we are now able to create GMG DotProof profiles with spot colors for special substrates such as foil or metal very quickly, achieving reliable color matching results,” says Michael Guggemos, Head of Reproduction at MCM Nägele GmbH & Co. Digital Repro KG.

Mark Brownett, MD at Brownett Ltd says:
“Using OpenColor has simplified the whole process for us resulting in a 50-75% reduction in overall costs.”

Less is more: Mini Strip instead of Mega Test Print

As an intelligent multichannel profiler, GMG OpenColor doesn't need large-scale test charts. A single, compact Mini Strip on the press sheet is enough to capture all data for an exact match - whether you are printing CMYK, spot colors, or both.

Accurate spot color simulation

GMG OpenColor calculates proof or separation profiles based on the spectral color information of the printing inks and the print specific process parameters.

From proof to print is very simple in GMG OpenColor

A few clicks will generate a matching separation profile for use in GMG ColorPlugin in Adobe Photoshop or in our color conversion solution GMG ColorServer.

Contract proof with GMG OpenColor

Precise prediction of overprinting effects

The combination of GMG OpenColor and GMG ColorProof ensures highly accurate proofing with spot colors, bridging the gap between contract proof and what actually happens on press. 

From proof to perfect separation of your print data

With GMG OpenColor, you cannot only create incredibly precise proof profiles, but also leverage your centrally stored data for calculating best quality separation profiles. For example, to adapt FOGRA39 data to your specific printing condition and substrate. The resulting quality and precision is astonishing, even for experienced experts, describing GMG OpenColor as “the most incredible tool of the last 20 years”.

The separation profiles created in OpenColor can be applied in GMG ColorServer, our color conversion solution, so that neutral gray areas, harmonious gradients, and in fact all of the benefits of the MX DeviceLink technology can easily be exploited for any printing process, color combination, and substrate. GMG ColorPlugin, the ingenious plugin for Adobe Photoshop, provides another means of leveraging GMG OpenColor separation profiles, e.g. by replacing CMYK channels with spot color channels via a direct connection to GMG OpenColor.
