Abstract:
A method for generating optically readable dot image data when binary data corresponds to presence or absence of an optically readable dot and said dot is printed in a virtual cell virtually formed on a printout medium, said method comprising:a first step of determining a count of pixels constituting said virtual cell as a minimum print unit in a typesetting device used for printing said dot on the printout medium; a second step of determining a count of pixels in said virtual cell associated with printout of said dot in consideration of enlargement of said dot when printed on the printout medium based on said dot image data; and a third step of, when a plurality of composition patterns are available for the dot image data consisting of the count of pixels determined at the second step, selecting from the plurality of composition patterns a composition pattern which minimizes a dispersion value of pixels constituting said dot image data, wherein said dispersion value is calculated for each of the composition patterns.
