In this paper, the method for generating print data of any resolutions based on ink volume from the original print data is presented. The print data in the form of halftoned levels are first transferred to the ink image according to the relation between halftone level and drop number obtained by the experiment of ink control. Then, the ink image of original resolution is converted to the ink image of desired resolution by the concept of conservation ink volume per pixel where the amount of ink drops in the unit area stays coherent in the conversion. Finally, each drop number of the converted ink image is transferred to the corresponding halftone level to generate the printing data that can be accepted by the printer. This method can be applied to all the applications related to printing such as printers and multi-function peripherals to save the time and labor in color-related experiments that are the prerequisite works in developing print modes for different resolutions. The print data of lower resolution can be inputted to the print system to generate higher resolution output. As a result, the memory usage is significantly reduced during the print process. Due to the ink loadings of the image remain identical in the completed resolution conversion process, the goal of maintaining color performance is achieved.
