Abstract
A method in described in which image data to be printed and a halftone matrix are provided. The halftone matrix comprises rows having randomized values within alternating ranges of values. The halftone matrix is applied to the image data to generate a plurality of halftone patterns.
Claims15
A method comprising:
- providing image data to be printed;
- applying a halftone matrix to the image data to generate a plurality of halftone patterns;
- wherein the halftone matrix comprises rows of elements having a sequence of ranges of values where each element is randomized within a corresponding range of values.
A printing device comprising:
- a printhead assembly;
- a processor;
- and
- a storage medium storing a halftone matrix and instructions for execution by the processor;
- wherein the halftone matrix comprises rows of elements having a sequence of ranges of values where each element is randomized within a corresponding ranges of values;
- and
- wherein the instructions, when executed by the processor, cause the processor to:
- receive image data;
- apply the halftone matrix to the image data;
- and
- print the halftone patterns using the printhead assembly.
8 more elements
A non-transitory computer-readable storage medium comprising a set of computer-readable instructions that, when executed by a processor, cause the processor to:
- generate a halftone matrix comprises rows of elements having a sequence of ranges of values where each element is randomized within a corresponding ranges of values;
- and
- applying the halftone matrix to image data to generate a plurality of halftone patterns.
