Abstract

There are provided an inkjet recording device and a test chart detection method capable of improving detection accuracy of a test chart recorded on a recording medium by ink having poor visibility irrespective of characteristics of the recording medium. An inkjet recording device includes: a fluorescent inkjet head that forms a fluorescent image on a recording medium (P) by ejecting ink containinga phosphor onto the recording medium (P); an ultraviolet light source that irradiates the fluorescent image formed on the recording medium (P) with ultraviolet rays; and an imager that detects fluorescence emitted by the fluorescent image by the irradiation of the ultraviolet rays.

Description

technical field [0001] The present invention relates to an inkjet recording device that discharges ink to a recording medium to form an image, and a test pattern detection method in the inkjet recording device. Background technique [0002] In an inkjet recording device, ink is discharged from nozzles of a recording head to form an image on a recording medium. In such an inkjet recording device, clogging of the nozzles of the recording head may occur, resulting in discharge failure in which ink cannot be discharged. [0003] In order to detect such a discharge failure, a method is adopted in which ink is discharged from each nozzle of a recording head, a predetermined test pattern is formed on a recording medium, and the test pattern is read by an inline sensor to determine whether the nozzle is not discharged. . [0004] In addition, in addition to yellow (Y), magenta (M), cyan (C), and black (Bk), inks used in inkjet recording devices are also known to be white (W) or tr...
