    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: A UV curable inkjet ink composition includes a monofunctional urethane acrylate component consisting of 5-50% by weight of the ink composition, the monofunctional urethane acrylate component comprising either of a monomer and an oligomer; a monomer component consisting of 10-80% by weight of ink composition; a photoinitiator component consisting of 1-15% by weight of ink composition; and an oligomer component, consisting of no more than 20% by weight of the ink composition, in addition to the monofunctional urethane acrylate component if the monofunctional urethane acrylate component is an oligomer.

    CPC classification number: C09D11/38 ,  C09D11/101

    Abstract: This invention relates to radiation curable ink compositions comprising one or more mono-functional monomers, optionally one or more oligomers, one or more antioxidants capable to react with peroxy radicals to generate radicals to propagate polymerization, and one or more photoinitiators comprising at least an acylphosphine oxide, wherein the ratio of the antioxidants to acylphpsphine is 1:1 to 1:20 by weight. The ink composition provides tack-free surface cure without requiring nitrogen or other inert gas during curing.

    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.

    Abstract translation: 增强的印刷系统，结构和工艺提供油墨的超声波处理，例如使油墨脱气和/或维持颗粒在油墨中的尺寸。 至少一个超声波模块，例如包括任何超声波探头或超声波浴，位于墨水输送系统内。 油墨被传送到超声波模块，并且超声能量被施加到油墨，例如足够的水平和持续时间以使油墨脱气，和/或减小油墨内颗粒的尺寸。 在一些实施例中，颗粒可以是附聚物，其中所施加的能量被配置为将附聚物的尺寸减小到可以通过打印头喷射的尺寸。 在其它实施例中，颗粒可以是金属颗粒，其中所施加的能量被配置为产生可以通过打印头用墨水喷射的较小的金属颗粒。
