PRINTED MATTER, QUALITY MANAGEMENT METHOD OF PRINTED MATTER, AND ITS QUALITY MANAGEMENT SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide printed matter whereby a printout process with the use of defective printed matter is prevented by performing quality inspection of a printing image in a preceding stage of carrying out a printout process of personal information or the like, and to provide a quality management method of printed matter, and its quality management system. PSOLUTION: A checksum value obtained by calculating from image digital data used when printing is carried out is included in a two-dimensional code displayed on the printed matter. A checksum of the image digital data used when printing is carried out is calculated, and the checksum value is turned to the two-dimensional code and displayed on the printed matter. In the preceding stage of printing out to the printed matter, the checksum value is read from the two-dimensional code displayed on the printed matter, and image data is read from the printing image and converted to digital data. Thereafter, the checksum of the digital data is calculated. The calculated checksum value is compared with the checksum value of the two-dimensional code. Only when the values are judged to match with each other, the data is printed out to the printed matter. PCOPYRIGHT: (C)2007,JPO&INPIT
