Title:
MULTIPLE WAVELENGTH UV CURING
Document Type and Number:
WIPO Patent Application WO2004081475
Kind Code:
A3
Abstract:
A UV curing apparatus and method is provided for enhancing UV curing of inks, coatings and adhesives having UV photo initiators therein by subjecting the UV curable inks, coatings or adhesives to UV light at different wavelengths. Preferably, the UV LED assemblies (10) are alternated in rows that form arrays (21) on block (20) such that, for example, a 390 nm emitting UV LED is positioned first followed by a 370 nm emitting UV LED, followed by a 415 nm emitting UV LED and this arrangement is then repeated through the row; or, for example, one row can have only 390 nm emitting UV LEDs, the next row can have only 370 nm emitting UV LEDs and the next row can have only 415 nm emitting UV LEDs.
