GMG Colour Management & Proofing Solutions 

Wherever a color goes it stays that color

Reliability, quality, and consistency are essential when colour is part of the final product. Access provides GMG’s industry-leading colour management software to simplify output and ensure results remain consistent across all devices and production environments.

Creative & Agency Solutions: Confidence from Design to Print

Creative teams need to know that the colours they approve will match the final result. By implementing accurate agency colour proofing, designers can review layouts in detail and verify colour accuracy before sending work to press. This reduces avoidable production changes and creates a clearer connection between design approval and final output.

Proofing for agencies – simple, reliable and economical

To assess layouts in detail, designers – and customers – must have an idea of exactly what’s going to be printed later. If you have in-house proofs with uncompromising color accuracy, the magic can happen.

GMG ColorProof produces those proofs. Just think, no more couriers or last-minute amends. And the idea of your creative department and production team finally being on the same page? Genius.

With remote proofing, GMG ColorProof delivers the process guarantee that so many international production operations need. GMG ColorProof makes sure you’re getting high color quality proofs – everywhere.

From image to proof to press: GMG ColorMaster is the ultimate RGB workflow

GMG ColorMaster converts print data at the last possible moment, from its RGB color space, into the respective targeted color space. No exceptions: with its virtual CMYK color space, GMG ColorMaster works with all color spaces from the classic printing processes.

This way, print results can be simulated before the actual printing process begins: only at the end of the workflow will the data be converted into a single CMYK separation, using GMG DeviceLink profiles.

Proofing Solutions

Twenty years ago we redefined the proofing sector. We still are

Proofing with GMG

Ads take time. And money. And effort. When true professionals are delivering a brilliant concept, they need to depend on a perfect proof.

With GMG ColorProof contone proofs can be produced to the most diverse international industry standards. GMG DotProof is the solution for cost-effective color-accurate halftone proofs based on the original imagesetter data; GMG FlexoProof is geared towards the flexo and packaging markets.

And when GMG proofing solutions are combined with GMG ProofControl, each proof result can be verified as being 100% authentic – which means it’s a proof you can depend on.

Print Proof-profiles for the packaging industry

GMG OpenColor creates consistent, efficient and reliable proof-profiles for the packaging industry

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 again and again, the result of those changed conditions can now be predicted accurately –with minimal expenditure.

GMG OpenColor makes GMG ColorProof a complete printing press simulator – and enables accurate proof simulation of the overprinting effects of spot colors using special multicolor profiles.

High quality results, no compromises

The GMG ProofMedia portfolio is recognized worldwide as being the medium of choice for leading color management experts and industry associations. Our production processes have incredibly stringent quality controls in place – and the GMG label is all you need to be confident it’s an original GMG proof.

Production Solutions: Repeatable Quality for Large Format 

For large-format banners, vehicle wraps, point-of-sale materials, decals, and similar applications, repeatability is key. GMG ColorServer and SmartProfiler support automated colour conversions, calibration, and profiling, helping production teams maintain consistent colour across daily workflows while reducing manual work. For teams looking to improve the full production process, Access also supports print factory workflow solutions that help streamline RIP, automation, and output management. 

What do a common large-format banner, an urgent brochure, a motif wallpaper and elegant curtain fabric have in common? Demanding customers – the color must be exact

GMG solutions provide a reliable system that ensures consistent reliability and the highest quality standards. With GMG ColorServer, you’ll achieve highly automated color management workflows, saving time and money for everyone involved. From now on, separation and conversion is no longer associated with an enormous amount of work.

GMG SmartProfiler on board

GMG SmartProfiler is a software-wizard that allows any user to calibrate, recalibrate and profile digital and large format printing systems easily and without advanced knowledge of color management.

Unlike other technologies, the software has useful presets for the different ink types found in large format and digital printing. Sources of errors are minimized because, as a user, you’re guided through the tasks, step-by-step.

Better print results with less ink

GMG InkOptimizer is the unbeatable application for printers wanting to save more than ink. GMG InkOptimizer stabilizes and optimizes the entire print run.

By standardizing the color composition of PDF files and increasing the levels of black ink, GMG InkOptimizer retains the original color and image quality – while reducing its production cost.

This is achieved by working in exactly the area where the human eye reacts most sensitively – the gray balance. These grays are stabilized and the neutral areas and tertiary colors, such as brown and olive shades, are made more consistent. In addition, contrast and shadow detail are improved.

Packaging Solutions: Navigating Complex Spot Colours

Packaging faces the most complex requirements, from varied substrates to spot colour combinations. Using GMG OpenColor and GMG ColorProof, teams can simulate overprinting and substrate behaviour before production begins. For reliable results, teams can also use GMG proofing media to support accurate colour reproduction and consistent proof quality. This helps predict final results, reduce press correction loops, and lower waste. 

A solution designed to tackle the specific opportunities and challenges of the packaging sector

Increasingly shorter product cycles, ever more complex color and substrate combinations, growing cost pressure …. to compete successfully, proofing solutions have to be reliable and powerful.

GMG is a leader in the packaging industry and has been for many years, developing GMG FlexoProof to prove that quality and standardization are no longer the reserve of offset printing.

As the world’s only solution to accurate simulation of the overprinting effects of spot colors, GMG OpenColor employs patented technology using special multicolor profiles

The spectral data calculation of GMG OpenColor includes printing technologies, substrates, and printing order. The results are so reliable that correction loops on the machine can be avoided.

With GMG ColorProof, profiles can be calculated ‘on-the-fly’: input files are simply placed in the corresponding hot folder of the proofing solution and subsequently processed automatically.
