ABSTRACT:
A modulated writing light beam (18) having a wavelength to which an imaging element (33) is sensitive and a reference light beam (46) having a wavelength to which the imaging element (33) is insensitive are generated and simultaneously directed to a moving optical device (22) to cause the writing light beam (18) to scan across the surface of the imaging element (33) in a first scanning direction (C) and the reference light beam (46) to scan across the surface of a light detecting element (50) in the first scanning direction (C) to generate signals indicative of the position of the writing light beam (18) on the surface of the imaging element (33). The writing light beam (18) is modulated and the imaging element (33) is moved in a second scanning direction (B) in response to the signals generated by the light detecting element (50). Thereafter the exposed imaging element (33) is processed to prepare a lithographic printing plate. The invention is applicable to both positive and negative imaging working systems.
