PRINTED MATTER AND READING SYSTEM

A reading system reading a color density of a printed matter formed with an ink whose color density changes depending on a surrounding environment comprises a reading apparatus and an information processing apparatus. The printed matter has a first region (reference region (100)) formed with the ink...

Zusammenfassung:	A reading system reading a color density of a printed matter formed with an ink whose color density changes depending on a surrounding environment comprises a reading apparatus and an information processing apparatus. The printed matter has a first region (reference region (100)) formed with the ink and a second region (sensor region (101)) formed with the ink identical to the first region. The first region is in a colored state or a decolored state and a color density of the second region is different from that of the first region. The reading apparatus obtains an image including the first region and the second region. The information processing apparatus determines color information of the second region by using color information of the first region as a standard. The printed matters include a circle type printed matter, a double-circle type printed matter, a dot type printed matter, a barcode type printed matter, a QR code type printed matter and the like.
