Abstract
A halftone dot image is produced by superposing image information produced by scanning an original on a halftone screen composed of a plurality of scanning lines constituted by electrically generated halftone screen signals and arranged side by side in a direction normal to a scanning direction in which the scanning lines extend. Each of dots of the halftone screen is formed with an integral number of scanning lines commensurate with a screen angle of the halftone screen. The halftone screen signals are equalized in level at mutually corresponding areas in the respective dots.
