ABSTRACT:
A method creates printing data applied to a printer that is capable of generating different sizes of ink drops. Firstly, a halftoning threshold table is created based on all possible combinations that are determined based on the quantity of the printheads and the sizes of ink drops quantity provided by each printhead. When the image data to be printed is received, each pixel of an image will correspond to one combination based on the halftoning threshold table. The corresponding combination is deemed as a halftoning encoded data and represented by several bits. These bits can be separated into plural groups, where the bits contained in each group are for driving a specific printhead. That is to say, each printhead has its own driving data so that the printing process will have superior efficiency.
