GMG Weihing Offers Wide Range of Media

As a provider of high-end proofing and color-management systems, GMG emphasizes that color accurate inkjet-generated proofs requires three components: the printing device, the RIP, and standardized consumables. Standardized media is an sometimes-overlooked element, but is critical in order for the proofing device, its inks, and the RIP software to consistently and accurately replicate the color gamut that can be achieved on an offset printing press. GMG notes that even minute variations in the media-manufacturing production tolerances can skew proofing results. Furthermore, new-generation pigmented inks used in devices such as the Epson Stylus Pro 7600 can pose some unique substrate-manufacturing challenges.

To keep pace with the growth in inkjet proofing, GMG has announced plans to considerably expand its line of proofing substrates. In addition to the well-known semi-matte papers used to proof many commercial print jobs, GMG now offers a 57-g matte paper for proofing newspaper jobs. Unlike butt rolls of newsprint, the inkjet-receptive material offers repeatability and protection against curling. The neutral surface of the paper enables GMG's ColorProof software to reproduce a simulation paper grain. It's also well-suited for halftone proofs.

Profiles are readily available for all GMG paper types, making it possible to replicate US and European press standards on popular models inkjet printers, including the Epson Stylus Pro 7600 and Hewlett-Packard Designjet 5500.

Founded in 1990, GMG Weihing is located near Stuttgart, Germany and specializes in high-end color management for the graphic-arts industry. The GMG ColorProof system consists of an integrated RIP, color engine, and profile editing software and output modules for various printing devices. Distinguishing features include support for all standard spot-color systems up to 64 individual color channels and a 4-D color-transformation engine. An optional FileOut module can automatically convert files from one CMYK color space to another, while retaining the integrity of the black channel. For example, proofing data for offset printing can be converted to proofing data for gravure printing. (GMG Weihing: www.colorproof.de)
