DOCUMENT DETERMINATION SYSTEM, DOCUMENT DETERMINATION METHOD, AND INFORMATION PROCESSING APPARATUS

To simply determine whether an object to be read is an authentic printed material.SOLUTION: A document determination system 1000 comprises: a server device 1 that stores document data 1114; a second multi-functional machine 2B that generates an authentic printed material that is an authentic printed material obtained by printing a document indicated by the document data 1114 stored by the server device 1 and printing at least part of the document with composite black being black represented by a plurality of inks; and a third multi-functional machine 2C that reads a print surface of an object to be read including the authentic printed matter and a copy printed material obtained by copying the authentic printed material. The server device 1 determines whether the object to be read read by the third multi-functional machine 2C is an authentic printed material based on the fact that at least part of the document indicated by the read data generated through reading of the third composite machine 2C is printed with composite black.SELECTED DRAWING: Figure 1 【課題】真正印刷物であるか否かを簡易に判定できるようにすること。【解決手段】文書判定システム１０００は、文書データ１１１４を記憶するサーバー装置１と、サーバー装置１が記憶する文書データ１１１４が示す文書が印刷され、且つ、当該文書の少なくとも一部が、複数色のインクで表現される黒色であるコンポジットブラックによって印刷された真正な印刷物である真正印刷物を生成する第２複合機２Ｂと、真正印刷物と、真正印刷物を複写した複写印刷物とを含む読取対象の印刷面を読み取る第３複合機２Ｃと、を備え、サーバー装置１は、第３複合機２Ｃの読み取りにより生成された読取データが示す文書の少なくとも一部がコンポジットブラックで印刷されているかに基づき、第３複合機２Ｃが読み取った読取対象が真正印刷物であるか否かを判定する。【選択図】図１
