Digital and Offset Printing: Seeking Workflow Oneness

The G7 specification formally defines process controls that determine the “visual appearance” of an image as perceived by the human eye rather than a mechanical device. It breaks from the long-standing practice of focusing on dot gain and instead uses gray balance (neutrality) as the basis for defining the metrics of “visual similarity” in a printed piece. Controlling tonality is the other key component of the specification, which is done by employing the concept of Neutral Print Density Curves set forth by the development team.
