  • Patent number: 10232606
    Abstract: A printing device prints an object on a medium by inkjet printing. The printing device includes: a glossy ink head that discharges ink droplets of a glossy ink having a glossy color; and a main scan driver that prompts the glossy ink head to perform main scans in which the glossy ink head discharges the ink droplets while moving in a predetermined main scanning direction. The glossy ink contains a glossy pigment and a solvent. In the main scans, the glossy ink head discharges the ink droplets plural times while moving in the main scanning direction to form ink dots at positions on the medium aligned in the main scanning direction. The ink droplets discharged from the glossy ink head each have a volume constituting a size that allows for contact on the medium between any ones of dots formed in each one of the main scans.

  • Patent number: 10220639
    Abstract: Both stability and high glossiness of a glossy ink used for printing can be achieved. A printer is provided that performs inkjet printing for a medium. The printer includes a glossy ink head as an inkjet head that discharges droplets of a glossy ink, a heater, and an ultraviolet light source. The glossy ink includes an ultraviolet-curable resin curable by being irradiated with ultraviolet light, a glossy pigment, and a solvent added to disperse the pigment. Particles of the glossy pigment have particle sizes less than or equal to 0.5 ?m. The heater heats the medium to volatilize and strip the solvent in the ink. The ultraviolet light source irradiates dots of the glossy ink on the medium with ultraviolet light after a preset waiting time has passed subsequent to a timing of the droplets of the glossy ink landing on the medium.

  • Patent number: 10144215
    Abstract: An inkjet print head includes an ejection unit having a liquid chamber for holding an amount of liquid, a electromechanical transducer operatively coupled to the liquid chamber for generating a pressure wave in the amount of liquid and a nozzle in fluid communication with the liquid chamber for enabling a droplet of the amount of liquid to be ejected through the nozzle. A method for detecting an operating state of the ejection unit includes the consecutive steps of actuating the electromechanical transducer to generate a pressure wave in the liquid; actuating the electromechanical transducer to suppress a residual pressure wave in the liquid; sensing an amplitude of the residual pressure wave in the liquid; and based on the result of the sensing step determining that the ejection unit is (i) in an operative state if the amplitude of the residual pressure wave is below a threshold or (ii) in a malfunctioning state if the amplitude of the residual pressure wave is above the threshold.
