Patent number: 7434906Abstract: A method and a device are used to generate print data of any resolutions based on ink volume from the original print data. 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 printing device.Type: GrantFiled: June 29, 2005Date of Patent: October 14, 2008Assignee: Industrial Technology Research InstituteInventors: Hsiao-Yu Han, Meng-Fen Lo, Yao-Wen Huang, Tung-Lin Wu, Chieh-Yi Huang, Jane Chang
