<P>PROBLEM TO BE SOLVED: To provide an inkjet recording method whereby the presence/absence of embedded information recorded by a transparent ink can be printed to be visually recognizable under a visible light, an inkjet recorder, and a printed matter. <P>SOLUTION: The inkjet recording method is a method for recording information by discharging ink liquid drops 30A and 30B from nozzle holes by an inkjet system and adhering the drops onto a medium 40 to be recorded. In recording information with the use of a coloring ink including a colorant, and the transparent ink including at least one of a fluorescent compound which emits a fluorescent light through irradiation of ultraviolet rays and a near infrared ray absorbing compound, a coloring recording part 42 is formed by recording desired information by the coloring ink inside a region 41 on the medium 40 where information is to be recorded by the coloring ink, and the embedded information 43 is recorded by the transparent ink inside the region 41. Hence, the presence/absence of the embedded information 43 can be visually recognized under the visible light. <P>COPYRIGHT: (C)2004,JPO |
