Abstract
An electromagnetic energy spot curing system is provided which utilizes a template which moves relative to a source of radiation in the electromagnetic spectrum, such as an ultraviolet (UV) lamp. A channel is formed through the template of varying widths so that during the course of relative movement, different intensities of radiation emanating from the source is continuously passed through the channel and applied to a desired location, typically a curable material.
