Abstract
A UV curing system and method for providing an adjustable beam profile are disclosed for UV curing for ultra high speed industrial applications, such inkjet printing, with improved print quality and efficiency. Also provided is a lamp head assembly for a UV source for such a system, which provides an adjustable beam profile for optimizing UV curing. The lamp head assembly comprises one or more light sources and reflectors or other optical elements, which may be relatively movable and adjustable, to adjust the beam profile to processing conditions and requirements for consistent curing efficiency and print quality at different print speeds. Specific features of such a lamp head assembly may permit adjustment of the spectral, spatial and temporal distribution of light for improved or optimized curing efficiency in ultra-fast UV curing applications.
