Abstract
As the desk-top publishing market has been rapidly expanding, high-quality image output technologies have been increasingly required; especially as to restoration for images with gradation like photographs. To meet this requirement, the authors developed a new high quality image recorder and tried some experiments of simulation image recording. In the high quality image recorder, the laser scanning optical system is used, including an anamorphic optical system. The laser spot diameter in the deflection plane is small as 30 micrometers in the image plane, and the scan length is large as 300 mm. A polygonal mirror is used as the beam deflector and the scanning optical system corrects the tilt error of the polygon facets. By using this image recorder, the authors obtained simulation image samples, which is based on the bi- level pixel of 1200 dpi density. The simulation image samples mean halftone images with some screen rulings. The simulation procedure and the result of the examination are reported.
