Specifically designed to meet the needs of the packaging industry, GMG OpenColor was making sure CMYK and spot colours print exactly the way you want them to. GMG’s patented OpenColor technology is unique. It enables accurate proof simulation of the overprinting effects of spot colours using special multichannel profiles. The spectral data calculation includes printing technologies, media types and printing order and its results are so reliable that profile iterations are no longer necessary. Profiles can now be created without a test chart. GMG OpenColor 2.1 now offers a measurement capability for custom patches. Whereas previously customers would require a specific test chart to create a color profile, GMG OpenColor 2.1 enables the measurement of full-tone patches from a print control strip, or even solid patches and tint patches on the running printed sheet and to create a profile from the captured spectral data, something no other profiling tool can achieve.
It is a complete printing press simulator, even if only CMYK is printed.
Where there is a need to change the colour sequence in an order, if the density or
substrate has changed, GMG OpenColor immediately calculates a new profile. Instead of printing on the machine again and again, the result of changed conditions can now be predicted accurately and with minimal expenditure.
If a continuous or halftone proof is required, GMG OpenColor can open new possibilities. Apart from checking the color accuracy, GMG OpenColor also makes sure moiré, incorrect trapping settings and other defects will not become the showstopper of the upcoming production run. Easily create halftone profiles for the colors you need, be it CMYK or spot colors, and print high-end halftone proofs in GMG DotProof and FlexoProof that predict the press result with dot-for-dot precision, including the screen rulings, angles, dot shape and dot gain.
“With GMG OpenColor we are now able to create GMG DotProof profiles with spot colors for special substrates such as foil or metal very quickly, achieving reliable color matching results,” said Michael Guggemos, Head of Reproduction at MCM Nägele GmbH & Co. Digital Repro KG.
