SELECTIVE INK CURE

摘要

Individually controllable ultraviolet (UV) light-emitting diodes (LEDs) are used to cure ink and generate different effects. The UV LEDs only expose specified areas to generate the different effect and can create multiple effects on the same substrate by exposing different areas to varying amounts of time or by performing a curing stage and post-dosage curing stages. The different effects include generating a glossy surface, a matte surface, and sharper images.

主权项

1. A method implemented with a printing system for selectively generating one or more print effects on one or more portions of an image on a substrate, the method comprising:
receiving instructions, wherein the instructions identify
one or more portions of the image less than the entire image that are selected by a user, anda degree of glossiness for the selected one or more portions that are specified by the user, wherein the degree of glossiness specified by the user corresponds to any level of gloss between no gloss and full gloss; dispensing inkjet ink onto the substrate to print the image on the substrate, based on the received instructions, using a print head carriage including a plurality of print heads, each print head including at least one nozzle for the dispensing of the inkjet ink; and with a lamp module associated with the print head carriage, wherein the lamp module includes a plurality of individually controllable ultraviolet (UV) light-emitting diodes (LEDs),
curing the printed image on the substrate, andselectively exposing the selected one or more portions of the image to different light intensities to achieve the degree of glossiness specified by the user for the selected one or more portions, based on the received instructions.
