ABSTRACT:
A method for representing a complex color by providing a mean-value a color mixture of low and middle color density so as to deposit at least two kinds of different color ink drops on a dot matrix in such a way as to permit a single ink drop to be in each of the greater part of the cells of the dot matrix. But a subtractive color mixture is used at high color density so as to deposit at least two kinds of different color ink drops on a dot matrix in such a way as to permit at least two kinds of ink drops to be superimposed in each of the greater part of the cells of the dot matrix. With a dot matrix of rectangular configuration of columns and rows of cells, each color is applied starting from a different corner of the matrix and progressing toward the diagonally opposite corner as the required level of color density progressively rises.
