Abstract
An inkjet recording device includes: an inkjet head that forms an image on a recording medium by ejecting ink containing a phosphor onto the recording medium; an ultraviolet light source that irradiates the image formed on the recording medium with ultraviolet rays; and an imager that detects fluorescence emitted by the image by the irradiation of the ultraviolet rays.
Claims8
An inkjet recording device, comprising:
- an inkjet head that forms an image on a recording medium by ejecting an ultraviolet curing type ink containing a phosphor onto the recording medium;
- a fixer that fixes the ink impacted on the recording medium to the recording medium;
- an ultraviolet light source that irradiates the image formed on the recording medium with ultraviolet rays;
- and
- an imager that detects fluorescence emitted by the image by the irradiation of the ultraviolet rays,
- wherein the ultraviolet light source is at a position further downstream in a conveyance direction of the recording medium than the fixer.

A test chart detection method, comprising:
- forming a test chart on a recording medium by ejecting an ultraviolet curing type ink containing a phosphor from an inkjet head onto the recording medium;
- fixing the ink impacted on the recording medium to the recording medium by a fixer;
- irradiating the test chart formed on the recording medium with ultraviolet rays from an ultraviolet light source;
- and
- in an imager, detecting fluorescence emitted by the test chart by the irradiation of the ultraviolet rays,
- wherein the ultraviolet light source is at a position further downstream in a conveyance direction of the recording medium than the fixer.
