Abstract
An apparatus for preparing a two-dimensional color code includes a reading section for reading an original image object to output to processing device; processing means having a code conversion section 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 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 restored image data on a printing body on the basis of the gradations of shades of color.
