Abstract
A halftone image recording apparatus has an interpolating function for interpolating previously obtained first halftone pattern data in the main scanning direction to obtain second halftone pattern data. Comparisons between input image signals and the second halftone pattern data per pixel are made to expose a photosensitive material on the basis of the results of the comparisons thereby to create a halftone plate. Through the interpolation, the recording density in the main scanning direction is increased in response to the rate of increase in pixel density.
