Abstract: A method of color halftone reproduction with reduced moire patterns and simplified calculations of color densities is disclosed. The method entails dividing a reproduction surface into an array of abutting halftone cells having centers aligned at a screen angle, preferably 45.degree. , with halftone cells in adjacent rows. The halftone cells each cover an area of M abutting horizontal dots long by N abutting vertical dots wide. The various system colors are applied to the pels, as required, in color patterns centered within the halftone cells. The patterns overlap one another to adjust the hue of the reproduction at the halftone cell location to the desired hue. The method is usable with permanent reproductions, such as printed paper, or with transient reproductions, such as the image on a CRT screen.
