Method and apparatus for ink jet printing

This invention describes a method for printing on fabric using a special ink that contains both a UV-curable component and a dye. The process involves jetting this ink onto the fabric, then exposing it to UV light to harden the ink, and finally heating it to activate the dye, making the color permanent. The preferred method uses sublimation dyes on polyester fabric.

Why it matters: Filed before the widespread adoption of efficient UV LED curing systems and advanced, integrated inkjet printheads. These advancements make the multi-step printing and curing process more practical and cost-effective today.
