G7® is IDEAlliance’sindustry-leading set of best practices for achieving gray balance and is the driving force for achieving visual similarity across all print processes.
G7® is a method defined by the Print Properties and Colorimetrics Working Group of IDEAlliance. The application of this method enables printers to reproduce a similar visual appearance across printing types and substrates. Today, through the PPC Working Group, experts from across the spectrum of printing disciplines contribute to this important IDEAlliance Methodology. G7® specifies the components of an image that define a similar "visual appearance" to the human eye.
To do this, the G7 Method:
- Defines a colormetric definition for gray balance, and
- Specifies gray balance in the midtones, image weight and image contrast from the highlights to the shadows, which are the factors that determine likeness of the visual appearance of an image.
