Recently Proof GmbH made available in their proof online shop the new US Proof Standards of SWOP and GRACoL with their 2013 profiles. Unlike the new Fogra51 and Fogra52 profiles from their Munich colleagues, the IDEAlliance have pushed their new standards forward and published new M1-based profiles already in 2013 – M1 meaning, that the new standards are measured in consideration of optical brightening agents (OBAs), and also contain a different white point than the previous SWOP and GRACoL profiles of 2006.
The release was perhaps a bit too early – even the Americans feel uneasy. So several documents of IDEAlliance regarding GRACoL 2013 and GRACoL 2006 almost discourages a necessity of a change towards the new profiles.
