Abstract
A printing method for printing an input image. Firstly, a halftone mask is generated. The input image is transformed into a halftone image through the halftone mask. The halftone image is then output for printing. The halftone mask is an array of N elements, and the following steps generate the halftone mask. An initial array of N elements is first provided. Thereafter, a first value is selectively assigned to an element in the initial array to generate a first array. The second to the Narrays are then recursively generated based on the first array in the following steps. A minimum energy element in an Iarray is first determined. An (I+1)value is then assigned to the minimum energy element to generate an (I+1)array, wherein I denotes 2 to N−1.
