X-Rite Announces New G7 Toolkit

About G7
G7 is an IDEAlliance specification that outlines methods to calibrate proofing systems and presses based on principles of digital imaging, spectrophotometry, and computer-to-plate (CtP) technologies. The goal of G7 is to simplify calibration and help printers reliably achieve a close “visual match” from proof to press and from press to press. G7 is intended to be in compliance with the ISO 12647 Standards and has incorporated aim values from ISO 12647 into their process. G7 is unique, however, in that it breaks from tradition by focusing on colorimetric data for gray balance in the mid-tones, image contrast and image weight in a precise and 100 percent colorimetric manner rather than relying totally on densitometric aims, i.e. dot gain, for each color, which alone does not define vital visual metrics of an image.
