Method for producing halftone dots in a halftone plate recording apparatus

摘要

A method for producing halftone dots in a halftone plate recording apparatus is disclosed. A photosensitive material is scanned with a purality of light beams and a plurality of minute dots in lattice-like arrangement are exposed in the range of the halftone dots areas of the halftone plate. Distribution of the quantity of light beams for recording the minute dots is gradually reduced from the center to the periphery thereof, and the intensity of exposure light beams on the minute dots is controlled by the degree of conformity of the minute dots or the pattern of their arrangement with the halftone dot areas.
