Lately, there has been a lot of discussion about pigmented inks for wide format ink jet printers.
Some people say use only pigmented ink for all ink jet printing because it lasts longer.
But, in most high resolution thermal printers like the Encad, reports are that the pigmented inks are dull and flat. In other words, they don't have the same eye-catching appeal as the more brightly colored dyes. Pigments and dyes are two types of colored substances commonly used in making inks. The color comes from the absorption of specific wavelengths of light. The chemical composition of the molecules in the dye or pigment determine which colors are absorbed.
