Abstract: Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.

Abstract: Enhanced printing systems, structures, and processes provide ultrasonication of ink, such as to degas the ink, and/or to maintain the size of particles within the ink. At least one ultrasonic module, such as comprising any of an ultrasonic probe or an ultrasonic bath, is located within an ink delivery system. Ink is delivered to the ultrasonic module, and ultrasonic energy is applied to the ink, such as at a sufficient level and duration to degas the ink, and/or to reduce the size of particles within the ink. In some embodiments, the particles may be agglomerates, wherein the applied energy is configured to reduce the size of the agglomerates to a size that can be jetted through the print head. In other embodiments, the particles may be metallic particles, wherein the applied energy is configured to create smaller metallic particles that can be jetted with the ink through the print head.
