Abstract
When threshold data of a threshold matrix are to be established, they are determined in an ascending or descending order so as to maximize the distance between the thresholds in the threshold matrix and other identical threshold matrixes positioned in surrounding relation thereto. After all the thresholds are established, multivalued image data are converted into binary image data using the threshold matrix. A halftone dot image produced on the basis of the binary image data is of a highly accurate nature free from dot gains.
