Recently, GMG successfully demonstrated to an international packaging printer that the company’s existing proofing workflow could benefit greatly from GMG’s suite of software solutions. Through investigation and testing it was concluded that the existing system could result in inaccurate and inconsistent results, and that GMG’s unique MX3 profiling technology could provide a very quick and powerful improvement. The solution provides a re-calibrated digital swatch output referencing the ink’s recipe, and proofing the result to an Epson SureColor device. This would normally have been a manual or digital process. The previous approach was shown to be very cumbersome. The target data would often move, as the hardware struggled to repeat the required colour reference from proof to proof and day to day. In contrast, GMG’s solution ensured the repeatability and consistency of colour over both space and time.
At the heart of the solution was GMG’s award-winning OpenColor software. Using the ink’s spectral data, the software can predict solids and tints on all of the printers substrate library database. It can even predict overprints of two colour’s or more – all without going to press. The spectral data allows for a 1de match on average without any intervention. GMG OpenColor has a built- in ability to repeat its output from proof to proof or even location to location, giving a rock solid solution to businesses operating on a global scale.
By using GMG ColorProof’s Remote Proofing capabilities and Epson digital printers, GMG has enabled the company’s sites around the world to match any sample using the CXF Data.
The solution can run out a proof showing either the standard solids and tint swatches or the actual job, applying noise settings to simulate the substrates in use within the company. The proof (printed on GMG’s own FOGRA certified media) is certified using GMG ProofControl Inline and the built-in EPSON spectro to verify each swatch and score the output match to the CXF data supplied/referenced.
