GRACoL Definition

GRACoL® stands for the General Requirements for Applications in Commercial Offset Lithography. 

GRACoL is a color reproduction Specification for sheetfed offset lithography. The GRACoL specification pertains to sheetfed offset printing using ISO defined inks and paper (#1 or #2). CGATS TR006 is based on the reference characterization GRACoL2006 Coated1. IDEAlliance no longer specifies TVI (solid ink density (SID), dot gain or print contrast) GRACoL targets. IDEAlliance does recognize the value of TVI as an important element of managing and monitoring the chemical and mechanical elements of printing machinery. Any reference you may read for GRACoL TVI metrics should be considered historical reference data only.
