Information display system and dot pattern printed material
Abstract:
Provided is an information display system and a dot pattern printed material to be used for the same, which are capable of easily displaying information only by reading a dot pattern, easy for update of the information, and capable of printing an even less visible dot pattern as compared to the conventional case. The information display system includes: a dot pattern printed material including a dot pattern having coordinate position code information, the dot pattern being printed on a printing object through gravure printing in a less visible and optically readable manner; optical reading means; information transfer means for transferring, to a server device, the coordinate position code information that is read by the optical reading means; a server device for outputting associated information that is accumulated in advance in association with the coordinate position code information; and information display means for displaying the associated information output from the server device. The dot pattern printed material is obtained by printing the dot pattern through the gravure printing with carbon black ink on a black printing layer that is formed with cyan ink, magenta ink, and yellow ink.
