Abstract
Official abstract text for this publication.
A printing apparatus is provided with a CPU. The CPU generates dot data where dots are regularly distributed and arranged in a case where gradation values which are represented by image data are a predetermined value or less by using a dither mask where thresholds are set for each printing pixel and comparing the gradation values of each of the pixels which configure the original image and the thresholds for each of the printing pixels which are set in the dither mask, and generates the dot data such that the degree of regularity of the dots which are distributed and arranged is reduced as the gradation values are increased in a case where the gradation values which are represented by the image data exceed the predetermined value through execution of a dot data generating module.
First claim
Opening claim text (preview).
What is claimed is: 1. A printing apparatus which performs printing on a printing medium, comprising: a dot data generating section which generates dot data which indicates a dot formation state for each printing pixel in a printing image which is to be formed on the printing medium by performing a half-toning process with regard to image data which represents gradation values of each pixel which configures an original image; and a printing image generating section which generat…
