In sheetfed offset, particularly in VOC-free formulations, it produces inks with excellent flow properties, but nevertheless high body. In web offset printing, inks based on Permanent Yellow GRS 80 tend less towards misting due to the special viscoelastic behaviour. Application Recommended for offset ink including sheetfed, heat set, and cold set printing ink, UV ink, paste ink.
