Magna Colours has developed the GNA mark which the company says will distinguish those textiles that have been made with no harmful chenicals.
Inks and products marked with GNA are guaranteed to be free of harmful chemicals such as PVC and alkylphenol ethoxylates (APEO) and must be water-based formulations. 
Magna Colours executive chairman Tom Abbey said, "those of us in the screen-printing industry are at an advantage. The exceptional performance of the latest water-based inks means there is now no need for solvent-based printing systems, immediately reducing the risk of harmful chemicals to our health and the environment.
"GNA is our way of leading the garment printing industry into more sustainable and environmentally friendly practices, and of changing the industry for the better. We wanted to think bigger than our own brand, and the development of GNA really underlines what we stand for.”
He explained that systems like Bluesign and Eco Passport look at production formulas and analyse CAS numbers that relate to individual chemicals. However, water-based printing ink is based mostly on polymers, which do not have CAS numbers and therefore cannot be adequately analysed.
