Welcome to GMG OpenColor

Packaging printing is one of the most complex areas in print production. Standardization is difficult to achieve due to the wide variety of printing technologies, spot colors, and substrates that define the market. The increasing complexity of packaging jobs—often requiring six or more inks—makes traditional press fingerprinting and profiling both costly and time-consuming. A particular challenge lies in predicting the overprinting behavior and color interaction between CMYK and spot colors.

To address the need for reliable color reproduction beyond the traditional four process colors, we developed GMG OpenColor—an advanced n-channel profiling software. GMG OpenColor is the first solution capable of accurately predicting overprinting behavior and color interplay while requiring only minimal measurement data. This is made possible by combining spectral measurements with a patented prediction engine, which uses mathematical models of printing processes to simulate what will happen on press. Thanks to centralized data management and an intuitive user interface, both beginners and experts can easily create high-quality profiles that are ready for immediate use.

An OpenColor proof profile visually predicts how your actual print will appear, while an OpenColor separation profile adapts your design (e.g., based on standardized ISO Coated v2 images) to your specific printing condition. As a result, your workflow becomes faster, more consistent, and more reliable—because proof and print are both safeguarded by the same centralized color management.

Benefits

• All-in-one profiling solution: Test chart generation, measuring, profiling, central storage, and profile distribution.
• Multi-purpose profiling: Contone and halftone proof profiles as well as separation profiles.
• Patented prediction engine: Fast and inexpensive profiling via mathematical models instead of extensive fingerprints.
• Predictable spot color overprints: Precise simulation of the overprinting behavior and color interaction of CMYK and spot colors.
• Easy fingerprinting: Profiles can be created with less data than traditional methods. Measurements of different test charts can be combined, even when printed on slightly different substrates.
• Color consistency throughout the production chain: Proof and print with the same color management capabilities.
• Support of diverse printing processes such as offset, gravure, digital, and flexo.
• Central data storage: All color data can be accessed by multiple GMG instances, including data from third-party databases.
• Profiling automation: Channel specific profile creation "on-the-fly" which significantly reduces the profiling effort.
