Nazdar qualifies direct-to-garment T-shirt printing for G7 colour control

Nazdar Ink Technologies has announced that its technical service group has qualified the first Direct to Garment (DTG) printed T-Shirt in the G7 methodology of colour control for grey balance. DTG is the newest category for G7 qualifications by IDEAlliance. 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. This methodology was created in 2006 by Don Hutcheson and used primarily by the offset lithography printing process at that time.

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. There are 17 different areas of qualification for G7 printing, with Inkjet Direct to Garment being the newest of these.
