Essential for a reliable proofing system: proof media in GMG quality

When it comes to accurately predicting print results, proofing media plays a key role. GMG ProofMedia offers high performance media in a number of substrate finishes to meet any projects’ needs. GMG's consistent product quality, guaranteed global availability, and professional support services have made GMG ProofMedia the premier choice for high-end contract proofs since 2001.

The new generation of GMG ProofMedia offers superior lightfastness, age resistance, and chemical resistance. Achieving accurate color time and time again has never been easier.

GMG ProofMedia has been optimized for use with GMG software, ensuring accurate print simulations with minimal setup and configuration.

Two product lines to match any need: GMG ProofMedia premium and GMG ProofMedia studio

GMG ProofMedia premium and GMG ProofMedia studio lines are configured to meet distinct use cases for proofing output.

GMG ProofMedia premium is the preferred choice of brand owners, print buyers, and pre-press professionals. Because of the substrate's superior quality and consistency, it is a reliable reference for legally binding color communication.

GMG ProofMedia studio enables an accurate color reference for uncoated, newspaper, and film applications, closely simulating the final substrate in terms of weight, surface texture and tactile quality.


OBA media for next-level color accuracy

Prints containing Optical Brightening Agents (OBA) differ from standard proofs if viewed under a light source that contains UV light. The GMG ProofMedia portfolio offers OBA-containing media to ensure the visual match between print and proof under light sources containing UV light. This way GMG ProofMedia ensures color accuracy in compliance with FOGRA 51/52 and GRACoL2013 standards. Learn more about OBA and FOGRA 51/52.

Distinctive blue tint in OBA media's exterior design and packaging help to clearly distinguish OBA and non-OBA media.
