GRACoL7 Proofing Specifications
Standards and specifications for the printing industry have been in existence for 40 years. The initial specifications for SWOP were first written in 1974 and have been modified and updated several times. In 2005, the SWOP committee formed a coalition with IDEAlliance to support a coordinated effort of standardized specifications and guidelines.
Out of this alliance, grew the new G7 calibration, printing and proofing process control methods. G7 is a new calibration method that defines gray balance and target neutral print density curves for three-color gray and black as the primary method for color control as opposed to the previous SWOP methods that focused on ink density and dot gain values.
The G7 process is intended to ensure a closer visual match between the proof and the final press sheet. Although originally intended for commercial offset printing, the G7 method is applicable to virtually any CMYK imaging process and has been successfully executed on a wide range of processes.
Four Lakes Colorgraphics has successfully demonstrated and implemented the process of G7 proof to press calibration. We have been qualified by Don Hutcheson of HutchColor, LLC (inventor of the G7 method) and are grateful for the assistance of Peter Weishaar of Eastman Kodak and Joe Suffoletto of PIA/GATF.
