Until now, the overprinting behavior and color interplay between CMYK and spot colors could only be reproduced by combining a CMYK profile with spot color libraries. This method required considerable effort to depict all possible combinations of spots and process colors "as accurately as possible". The major drawback of this method was the inaccurate simulation of spot color overprints.
With the increasing use of multicolor printing, the simulation of spot color overprints currently poses one of the biggest challenges for packaging printers. GMG OpenColor is the first profiling tool on the market that provides this vital capability. Offering an astonishingly accurate prediction of overprints, GMG OpenColor creates high-quality multicolor profiles simulating the printing behavior of diverse printing technologies, media types, and screenings.
GMG software products such as ColorProof can access GMG OpenColor via a direct connection and request a multicolor profile, which is then dynamically calculated by OpenColor on the basis of spectral data. GMG OpenColor does most of the work automatically, so that time-consuming manual tweaking and editing are now a thing of the past.
GMG OpenColor comes in different versions tailored to fit different printing technologies and customer requirements.
Ian Scott, managing director at GMG comments, "Offering print predictability of the combination of process and spot colors - that was previously considered impossible - we can now provide the market with the long sought-after solution: GMG OpenColor.“
Located in Tuebingen, Germany; GMG is a leading developer and supplier of high-end color management software solutions. With more than 25 years of experience in the graphic arts industry, the GMG brand is synonymous with a guarantee for high-quality solutions for everything to do with color. GMG's goal is to provide complete solutions for standardizing and simplifying the color management workflow in order to achieve consistent colors on all media types and with any printing technology. Today, more than 11,000 systems are in use among customers around the globe.

Based on the 4-D color-transformation engine, the proofing solution GMG ColorProof provides the most accurate way of calibrating digital inkjet proofing devices to produce contract color proofs precisely matched to the printing process. GMG DotProof® enables users to generate contract quality halftone proofs, using the original bitmap data of the output RIP. GMG FlexoProof is specifically tailored to the needs of the packaging industry, simulating any kind of substrate structures and spot colors in the halftone proof. GMG ProofControl guarantees reliable and complete quality control of digital color proofs based on a defined standard. GMG ProofMedia is a range of proofing-specific substrates manufactured to strict tolerances specifically for color critical applications. www.proofr.com is an internet platform enabling online proofing services in GMG quality through a worldwide network of remote proofing locations. GMG ColorServer, with automatic hotfolder technology and based on the Adobe PDF Library, provides fully automatic color conversions for all printing processes – CMYK-to-CMYK, RGB-to-CMYK and RGB-to-RGB. GMG InkOptimizer automatically reduces chromatic colors, thus providing cost savings by reducing unnecessary ink usage, along with better print stability on press. GMG FlowConnect enables the complete integration of the color management solutions GMG ColorServer and GMG InkOptimizer into current workflow systems. The GMG SmartProfiler wizard allows the profiling and calibration of different output devices, such as digital presses or large format systems, easily and quickly. United in this one application, the GMG ProductionSuite offers the entire range of functions required today in a modern wide-format production environment: efficient job preparation, data preflight, color management, identical repetition, lower cost through reduced ink consumption, etc.
