Method and device for achieving color development on a print medium by ink jet printing

摘要

An ink jet printing method includes the steps of: shooting an ink containing a color material in a penetrant by ink jet method to a surface of a print medium; and supplying only a penetrant containing no color material at a position on the print medium corresponding to a position at which the ink has been shot to diffuse the supplied penetrant in the print medium in order to control distribution of the color material supplied in the print medium as the ink is shot at the print medium.

1. An ink jet printing method for shooting an ink containing a color material in a penetrant at a surface of a print medium having a permeability to the ink and allowing a color to develop in the print medium, the method comprising the steps of:
entering information on the print medium and an image to be printed on the print medium; calculating a target color development and a target color material distribution based on the entered information on the print medium and the image to be printed on the print medium; calculating an amount of the ink to be shot and an amount of the penetrant to be supplied for achieving the calculated target color development and the calculated target color material distribution; shooting the ink in the calculated amount of the ink to be shot by ink jet method to the surface of the print medium; and supplying only a penetrant containing no color material in the calculated amount of the penetrant to be supplied to a position on the print medium corresponding to a position at which the ink has been shot to diffuse the supplied penetrant in the print medium in order to control distribution of the color material supplied in the print medium as the ink is shot at the print medium.
