Use of UV LED lamps in printing industry
DROLED UV LED lamps with high intensity are used in printing industry to cure UV LED inks. All of them provide high quality of the print, both glossy and opaque finishing, as well as high chemical, mechanical and scratch resistance.
Ink drops transferred from the printhead to the support can be deformed or moved from their original position, even within few milliseconds. UV LED lamps are specific for the pinning of the ink and are positioned immediately after the print heads, so that the ink will gel and will be blocked to its original position.
Thanks to the instant switch On/Off all DROLED UV LED lamps are used only during the “curing” phase of the printing cycle, allowing a significant energy saving. Also depending on the printing width, the emitting window can be partially switched on/off and regulated.
