PPROBLEM TO BE SOLVED: To provide a method of constituting a group of image patterns, which is suitable for normal and low resolution printers, improves the efficiency of information description, minimizes reading areas, and does not degrade the image quality of printed images in consideration of characteristics of a printing screen. PSOLUTION: An information embedding device includes: a means for inputting image information; a means for converting additional information to a group of image patterns as a screen code which is a pattern-recognizable geometrical or physical information-embedding code that has characteristics of a printing screen; a means for constituting woven pattern image information using the group of image patterns; and a means for overlapping the input image information on the woven pattern image information and outputting it, or outputting only the woven pattern image information.
