IMAGE, RECORDING METHOD, INFORMATION RECOGNITION METHOD, AND INFORMATION RECOGNITION SYSTEM

摘要

It is possible to easily record a plenty of information without using a layered structure of color material layers and to provide an image or the like which cannot be easily forged/altered. In an image formed by superimposing a plurality of inks, a first ink layer is formed by a first ink having a fluorescent light emitting characteristic on a recording material and a second ink layer is formed by a second ink on the first ink layer, wherein the first ink layer is partially exposed to the second ink layer.
