Abstract
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.
