摘要

PROBLEM TO BE SOLVED: To solve the problem that the dithering method and error diffusion method are indispensable for reproducing a density of each pixel in a printer in an inkjet system.;SOLUTION: (a) In the case where a printing head with a nozzle array of k or more arrays corresponding to k types of ink (k is a natural number of not smaller than 2) of different concentrations is made an output device, (b) one pixel is formed by a dot group of m rows×m columns equivalent to a resolution of 1/m (m is a natural number of not smaller than 2) of a nozzle pitch. Moreover, when each dot is formed by superposition of ink droplets of the maximum of n shots (n is a natural number of not smaller than 2), (c) a density expression of the maximum of n+1 gradations by any of the k types of ink is made corresponding to each dot, and a density expression given by a combination of the whole dot group of (m rows)×(m columns) is made corresponding to all of density input values.;COPYRIGHT: (C)2006,JPO&NCIPI
