How are different printing processes matched via G7?

G7’s success was so spectacular for GRACoL workflows, that G7 methods were tested on other workflows such as SWOP. Managing gray so carefully paid dividends in SWOP workflows and in other workflows as they were tested. Today, a series of printing conditions has been defined in a new standard, CGATS 21-2 (ISO PAS 15339). This family of print conditions, referred to as the CRPC1-7,  has seven categories, each with its own reference data set. All of them share a visual appearance because they’re all based on G7 neutral gray appearance.

These seven sets are called:

• ISO15339-CRPC1 - Typical ColdsetNews – Small gamut printing (newsprint)
• ISO15339-CRPC2 - Typical HeatsetNews Moderate gamut printing on improved newsprint type paper
• ISO15339-CRPC3 - Typical PremUncoated Utility printing on a matte, uncoated type paper
• ISO15339-CRPC4 - Typical SuperCal General printing on super-calendared paper
• ISO15339-CRPC5 - Typical PubCoated Typical publication printing
• ISO15339-CRPC6 - Typical PremCoated Large gamut (typically commercial) printing
• ISO15339-CRPC7 - Typical Extra Large Extra-large gamut printing processes
