A little about G7 Certification
The G7® Method is a best practice procedure to ensure accurate color reproduction. G7 stands for grayscale plus seven colors: Cyan, Magenta, Yellow, and Black (CMYK) and the Red, Green, and Blue (RGB).
G7 certification helps ensure the production of the highest quality, consistent and accurate color graphics. If all print products have the same gray balance and neutral tonality defined by G7, they will look remarkably alike to the human eye, a key component in effective brand quality management.
