To achieve highly reliable and productive inkjet printing systems for textiles, we have developed a black dye dispersed ink that meets the requirements of dye safety, image stability/durability, storage stability, and, most challenging, jettability. Jettability in this ink was achieved by using a wetting agent to strengthen surface energies and decrease the flocculation that causes structural viscosity. The result was Newtonian fluid behavior that allows superior jettability.
