G7 is the colour control methodology that achieves colour similarity across all print processes. The method balances the four primary process printing colours, CMYK and their three overprints RGB (the 7 in G7) to achieve neutral grey (the G in G7) in a raster image.

In 2008, Nazdar Consulting Services introduced the G7 methodology to the screen and wide format graphic ink jet printing processes as the best way to achieve a common appearance in images when printed on different substrates, using different printing processes. This was a big departure from the existing printing specifications (SNAP, GRACoL, and SWOP) which were specific to the offset printing process on a certain grade of paper.
