 Re: eco friendly inks
It depends on your definition of "eco friendly." Certainly a plastisol ink without PVC and phalates is better than an ink with PVC and phalates, but that doesn't necessarily mean it's environmentally friendly. Unleaded gas is a heck of a lot better for the environment than leaded.
Some people claim that water-based inks are the most eco friendly, but this is debatable. Some shops print with only plant-based organic inks, but I don't believe these are commercially available. |
