ADDITIONAL INFORMATION RECORDER, PRINTER, PRINTING SYSTEM, ADDITIONAL INFORMATION RECORDING METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To propose a structure which enables simple classification without using a device for the exclusive use.

SOLUTION: At the time of recording additional information to a film-like sheet which coats the surface of a substrate, the additional information recorder carries out (a) a process of reading out classification information related to a received event generated at the time of printing reception from a storage part, and (b) a process of varying energy applied to a surface of the film-like sheet between a recording region for the classification information and the other region, and recording the classification information to the surface of the film-like sheet in the form of a watermark.
