Printer, printing method, and ink

A printing method of performing inkjet printing for a medium,

• the printing method using:
• a glossy ink head as an inkjet head that discharges droplets of a glossy ink which is an ink with glossiness;
• a heater that heats the medium;
• and
• an ultraviolet light source that irradiates dots of the glossy ink formed on the medium by the glossy ink head with ultraviolet light,
• wherein the glossy ink including:
• an ultraviolet-curable resin curable by being irradiated with ultraviolet light, a glossy pigment, and a solvent added to disperse the glossy pigment,
• particles of the glossy pigment having particle sizes less than or equal to 0.5 μm,
• the printing method comprising:
• heating the medium using the heater to volatilize and strip the solvent in the glossy ink;
• and
• irradiating the dots of the glossy ink on the medium with ultraviolet light emitted from the ultraviolet light source after a preset waiting time has passed subsequent to a timing of the droplets of the glossy ink landing on the medium.

A glossy ink for use in a printer that performs inkjet printing for a medium, comprising:

• an ultraviolet-curable resin curable by being irradiated with ultraviolet light;
• a glossy pigment;
• and
• a solvent added to disperse the glossy pigment,
• wherein particles of the glossy pigment having particle sizes less than or equal to 0.5 μm,
• in a case that the printer performs the inkjet printing,
• the solvent being volatilized and stripped by the heater,
• dots of the glossy ink formed on the medium being irradiated with ultraviolet light emitted from the ultraviolet light source after a preset waiting time has passed subsequent to a timing of the droplets of the glossy ink landing on the medium.
