Process standards and consistent quality

What is G7?

G7 is a method for managing color across multiple devices - it guarantees that color will visually match throughout the production process - from proof to print. G7 was developed by IDEAlliance and the GRACoL Committee. According to The G7 Specification document, G7 is "a specification that defines the factors that can be used to provide consistent gray scale reproduction across multiple devices, processes, and media."

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
  • 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"

What is a G7 Master Printer?

A G7 Master Printer is a printer that has passed all of the testing, training, and all evaluations required by IDEAlliance and GRACoL for this qualification. In other words, we are qualified to deliver consistent lithographic color in accordance with IDEAlliance's G7 specifications.
