According to the IDEAlliance organization, the impetus for the development of G7 was the frustration expressed by print buyers when receiving proofs and prints that had matching dot gain measurements, but clear visual differences. They were asking for metrics that more closely relate to the visual appearance of a printed image. The G7 method focuses on neutrality and tonality as key metrics for process control to achieve a similar printed appearance across the full range of output devices.
