Abstract

PURPOSE:To obtain a large quantity of information by printing bar codes in many colors and scanning these symbols by the sensors that react only with each specific color. CONSTITUTION:Two types of bar codes (a) of red and (b) of blue are put on each other and printed in double colors as shown in (c). Then a blue color filter is first used to read the bar code symbols printed on a print surface in red. While a red filter is used to read the bar code symbols printed in blue. Thus it is possible to read the blue information only.

Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は高情報密度のバーコード方式に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to high information density barcode systems.
