How dye classes, shade depth, auxiliaries, and finishing chemistry interact to shape wastewater treatability — and what printers can realistically influence.
Wastewater impacts from textile production are a concern that sits upstream in the supply chain, far removed from print operations. Most print service providers (PSPs) and OEMs do not operate dyehouses, yet the materials they specify — including fabric construction, color intensity, print compatibility, and performance finishes — directly influence the chemistry used earlier in the supply chain. Those choices shape both …
