Abstract
An imaging system comprising a source of light movable with respect to a writing element and projectable thereon to generate an image, a focusing device is provided for focusing a light source which generates a first beam of light of a wavelength selected to be actinic with respect to the writing element. At least a portion of the first beam of light is absorbed by the writing element.
