Claims11
A method of rosette-free printing comprising:
- in a printing device whose color plane misregistration is less than 15 percent of a screen ruling of a halftone screen, printing each color plane of multiple color planes of a multicolor image using a single halftone screen, the single halftone screen being the same halftone screen used to print each of the other color planes.
A printer for rosette-free printing comprising:
- a stable color registration print engine;
- a screen generator to create halftone screens;
- and
- a screen manager to use a single and same halftone screen for printing all color planes of a multicolor image;
- wherein the stable color registration print engine comprises a print engine to provide a color plane misregistration between the color planes of better than 15% of a screen ruling of the single and same halftone screen.
2 more elements
A non-transitory machine-readable storage medium storing instructions for rosette-free printing that when executed by a processor of a printing device, cause the printing device to:
- generate a first halftone screen;
- and
- print all color planes of a multicolor image using the first halftone screen with a color plane misregistration between the color planes that is better than 15% of a screen ruling of the first halftone screen.
