The Mountain® uses only environmentally friendly water-based inks and Dyes.
Most screenprinters use solvent based inks made primarily of plastic (petroleum) that have a rough feel and contain toxic phthalates. While many printers are trying to kick the chemical habit and learn how to use waterbased inks, we are light years ahead of them. We are literally pioneers of using waterbased ink and have perfected it’s use to create photo-realistic imagery that is not attainable by other screen printers.
We use waterbase inks to create the amazing soft feel to our prints (99.5% of other T-Shirt printers use petroleum based ink to create their designs on apparel)
