<P>PROBLEM TO BE SOLVED: To provide a method for printing a printed material for optical scanning, configured to print an optical scanning part using a line type color inkjet printer. <P>SOLUTION: An optical scanning part 4 is printed in a black color formed by mixing a black ink K and at least one of color inks C, M by using a line type color inkjet printer including a print head for a black ink K and color inks C, M. The color inks C, M fill a space with no color ink K deposited thereon or overlaps a pale black ink K, thereby increasing the concentration of the optical scanning part 4 as compared with the case where the optical scanning part 4 is printed with only the black ink K. The optical scanning part 4 can be printed at concentration required by an optical scanning device, even at a printing speed at which a printed matter is printed at a low concentration only with the black ink K. <P>COPYRIGHT: (C)2013,JPO&INPIT |
