ABSTRACT:
Each halftone dot is randomly placed, and the halftone dot area rate at which half of the halftone dots join with their adjacent halftone dots in an image area having a uniform image density is set to a value larger than 50%. When each halftone dot joins with its adjacent halftone dots, a plurality of joining points at which the halftone dot joins with-its adjacent halftone dots do not simultaneously start to join with the adjacent halftone dots.
