Recording a hard copy of a digital image is done by exposing a film with emulsion coating to light (mainly laser light) and then developing the film by wet chemical processing or by dry thermal processing. Since their introduction in the 1980s, (1) laser imaging systems have advanced in terms of dynamic range, archiving properties and handling. (2) Their operation is now well established. During the laser imaging process, image signals are input as either analog video signals or digital data. A laser beam exposes the film, line by line, with the beam's intensity modulated by the video signal or the numerical value of the pixels in the corresponding line of laser imager ...
