GMG OpenColor

Proof profiles for packaging printing more efficient and reliable than ever before:
GMG OpenColor

Calculate the behavior of overprinting spot colors and save valuable machine run times

GMG’s patented OpenColor technology is unique. It enables accurate proof simulation of the overprinting effects of spot colors using special multicolor 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.

Use the data from your proofing projects for perfect separation of your print data too

With GMG OpenColor, not only can you create incredibly precise proofing profiles but also leverage your centrally stored data for calculating top-quality separation profiles. You can use GMG OpenColor separation profiles to prepare FOGRA39 data for your specific circumstances and required substrate, for example. The resulting quality and precision is surprising even for experienced experts. Industry specialists are consequently describing GMG OpenColor as “the most incredible tool of the last 20 years,” while more than a few have used the term “separation 2.0” to describe the advances made.

With GMG ColorServer, conversion is extremely straightforward – and produces unprecedented results. 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 plug-in for Adobe Photoshop, provides another means of leveraging GMG OpenColor separation profiles. With its special additional features, GMG ColorPlugin is proving attractive to a great many Photoshop users involved in the packaging field. Many of the time-consuming workarounds previously needed have now been consigned to the past.

New: Continuous or halftone proof? OpenColor brings 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.

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.

Seamless interaction: precise calculation with GMG OpenColor – accurate output with GMG ColorProof

Profiles can be calculated on-the-fly for connected GMG ColorProof systems. To do this, the input files are simply placed in the corresponding hotfolder and are subsequently processed automatically.

The centralized storage of color data in GMG OpenColor and the color stability of GMG ColorProof ensure absolutely accurate results and repeatable quality. To ensure consistently high production standards – even across sites – multiple GMG ColorProof systems are able to access GMG OpenColor and consistently use the same spectral color data and profiles.
