Latex based digital inks / water based fabric ink printing

Printing can be a toxic business. In the mechanical printing world, oil based inks gave way to soy based. The York Newspaper Company newspaper products are printed with soy based ink

In the increasingly digital reformulation of large scale printing Hewlett-Packard has developed latex inks for large scale printing operations like billboards. According to the HP site, "new water-based HP Latex Inks provide the benefits of solvent-ink technology--like outdoor durability--without imposing the typical environmental, health, and safety considerations."

An HP Designjet Latex printer and a Gandi Aquajet Dye Sub printer that uses water based inks to print on fabric will be part of a graphics trade show at Color Reflections at 400 Green Street, Philadelphia on Earth Day.
