Paper Abstract

Thermal recording with a laser beam is a promising process. More thermal recording applications in the graphic arts market and also in the medical and PCB imaging markets are surfacing in recent years. Thermal recording has advantages over traditional photographic recording in that it is dry and environmentally benign. Also thermal recording is a threshold process and therefore yields sharper images. Thermal recording media, however, require much higher powered lasers to record than conventional photographic media. We must therefore carefully determine the optimal parameters for recording thermally most efficiently. In this paper, we determine the minimum beam power requirements, in terms of recording media format, throughput and media sensitivity. We also analyze in this paper the spot profile required to achieve the optimal recording efficiency, assuming it is a controllable design parameter. Since the efficiency is not the only performance requirement from a recording system we discuss other important parameters of image quality which affect the spot profile and beam power choice for a thermal recording system.
