From source to destination color space

Today, both large corporations and small artisan brands wield global influence. This necessitates that printing projects be produced across different countries and on various substrates. Therefore, color conversion of print data is crucial for achieving consistently accurate color results. The industry-leading GMG MX technology delivers high-quality color conversion, ensuring stable performance even in sensitive color areas while preserving the black channel. The outcome? Consistent, reliable results across all printing processes and materials.

Maintain consistent color

Once printed products exceed industry standards such as ISO, PSO, GRACoL, or SWOP, specific adjustments to the print data become unavoidable. Using spot colors, special substrates, or ever-changing printing conditions typically requires a tailored analysis of either the print data or the printing press itself. Tools like GMG OpenColor or GMG SmartProfiler make creating individual profiles intuitive and straightforward.

Color Management in Packaging and Printing

GMG OpenColor utilizes a proprietary spectral calculation model that accurately predicts the interactions among different processes, substrates, and overprint sequences. Leveraging patented conversion technology, it enables color-accurate simulations—even in the absence of test charts. In addition to spectral color data, the system also takes into account printing processes, substrates, and even ink sequences. Should any parameters change, the profile can be quickly recalculated without requiring the production of a new proof.

GMG OpenColor establishes a building block for reliable color communication and enables rapid calculation of parameter changes without the need to run new proofs. By integrating with GMG ColorProof, it dynamically calculates multi-color proof profiles based on the colors assigned in the print file. Additionally, by leveraging halftone profiles, potential issues such as moiré patterns and incorrect trapping settings can be identified well in advance.

Save time by automating workflows

The demands for deadlines and cost savings have made it nearly impossible to manage the color workflow manually. What we need is a reliable system that meets the highest expectations in terms of quality, consistency, and repeatability. Thanks to GMG ColorServer, automating the color management workflow has now become a reality. Separating and converting print data no longer requires complex manual intervention, saving users significant time and money—especially when dealing with print data originating from multiple sources. Designed for seamless integration with third-party systems, GMG ColorServer stands out as a straightforward choice for any environment.

Meanwhile, GMG ColorServer leverages its advanced MX technology and GMG OpenColor to adapt print data to the appropriate conditions, ensuring optimal conversion for each standard.

Despite the abundance of digital and large-format machines, as well as the wide variety of printing substrates, achieving consistent results remains essential—demanding a robust solution. GMG ColorServer Digital delivers the color quality customers expect. This application is both precise and highly efficient. Leveraging GMG’s unique MX technology, RGB, CMYK, and even mixed image data are automatically converted into the desired output color space. Meanwhile, GMG SmartProfiler—an integral part of GMG ColorServer Digital—provides an intuitive, step-by-step user guide for calibrating and recalibrating a diverse range of digital and large-format printers. With GMG SmartProfiler, users can quickly and effortlessly create profile configurations tailored to specific printing conditions.

Optimize the process using GMG InkOptimizer

Removing undercolor optimization from print data can save up to 20% of ink. Importantly, GMG InkOptimizer not only helps you save money but also stabilizes the printing process and enhances shadow details. This software employs cutting-edge conversion technology to increase the proportion of black while reducing neutral grays and colors in shadow areas. The result is more consistent print runs and superior output quality.

Flexible and Efficient Color Management

In traditional printing, brand colors are typically reproduced using specially mixed inks. In contrast, digital printing relies on a fixed set of colors. Therefore, it’s essential to use the printer’s standard ink palette to accurately reproduce specific brand colors. GMG ColorServer Multicolor automatically converts all spot colors into the desired output color space—whether CMYK or CMYKOGV—ensuring that the printed results look identical every time.

The Multicolor workflow, featuring a fixed color set, offers significant advantages in traditional printing. The only requirement: efficient color management using GMG ColorServer Multicolor means not switching spot colors from one job to the next—but instead, each job is printed using the same predefined color set. This approach saves on setup costs, greatly streamlining production and enhancing operational flexibility—both on-site in the print shop and across multiple locations.

Summary

GMG offers a comprehensive color management solution that leverages its innovative MX technology, OpenColor spectral calculations, and ColorServer automated workflow to help printing companies achieve consistent color reproduction across countries, substrates, and processes. The system intelligently converts between RGB, CMYK, and hybrid color spaces, precisely matches spot colors, optimizes ink usage (resulting in savings of up to 25%), and supports dynamic proofing and fully automated workflows. This cutting-edge approach effectively addresses the industry challenge of color inconsistencies caused by varying standards, materials, and processes in global print production.
