Two-dimensional color code, preparing and restoring method for the code and apparatus therefor

摘要

An apparatus for preparing a two-dimensional color code comprises a reading section (2) for reading an original image object (20) to output it to processing means (3); processing means having a code conversion section (11) to output two-dimensional color codes corresponding to gradations of shades of color separately of CMY colors in original image data of one pixel read; and a printing section (4) for printing on a printing sheet. An apparatus for restoring a two-dimensional color code reads the two-dimensional color code at the reading section to output the gradations of shades of color separately of CMY colors. The printing section prints (4) restored image data on a printing body on the basis of the gradations of shades of color. <IMAGE>
