GMG ColorProof Receives SWOP and GRACoL Certification

Until a review this year, all SWOP tests were based upon one paper type and were visually evaluated. There were very large tolerances, and almost all applications were approved. These and other factors demanded that SWOP re-evaluate and update the certification program. As part of IDEAlliance’s commitment to support the update of SWOP specifications, the Print Properties Committee initiated a series of research and development efforts to provide a scientific basis for modernizing SWOP and GRACoL. SWOP’s adoption of the G7 methodology strengthened the association’s ability to determine the closeness of a visual match numerically. Following the G7 methods using spectrophotometry and CTP, the outcome was a new visual-appearance-based SWOP specification designed to enable printers quickly and accurately to replicate the visual appearance of imagery from proof to press. Proofing systems must now conform to these new specifications.
