  • Patent number: 9327522
    Abstract: An image recording apparatus includes a first print head that discharges a first liquid that is cured through irradiation of light from a nozzle towards the recording medium; a second print head that discharges a second liquid in which a content rate of a tri-functional or higher polyfunctional monomer is different from that of the first liquid and that is cured through irradiation of light from a nozzle towards the recording medium, and is provided at a different position in the transport direction from the first print head; and an irradiator that irradiates the recording medium with light, and is arranged between the print heads in the transport direction, in which the irradiator emits light having directionality in a direction receding in the transport direction from a print head that discharges a liquid with a higher content rate from the print heads.

  • Patent number: 9016849
    Abstract: An electromagnetic wave irradiation device includes an irradiator which irradiates electromagnetic waves onto a liquid droplet which has been adhered to a recording medium, an irradiation controller which causes the irradiator to irradiate the electromagnetic waves periodically such that a frequency of an irradiation period in which the electromagnetic waves are irradiated is a predetermined frequency, and a time setting unit which sets a time ratio obtained by dividing a length of an irradiation time by the irradiator in the irradiation period by a length of a termination time during which the electromagnetic waves are not irradiated by the irradiator in the irradiation period to be a value of greater than or equal to 0.2 and less than or equal to 2.

  • Patent number: 8807733
    Abstract: An electromagnetic irradiation device is provided. The electromagnetic irradiation device includes an irradiator which irradiates droplets that are attached to a recording medium with an electromagnetic wave, an irradiation control unit which causes the irradiator to periodically irradiate the attached droplets with the electromagnetic, and a frequency setting unit which sets a frequency of an irradiation period which is a period during which the irradiator is caused to emit the electromagnetic wave. The period may be set to be equal to or greater than 5 Hz, and less than 1000 Hz.

  • Patent number: 8789910
    Abstract: An image formation apparatus includes a liquid droplet adhesion unit which makes a first and second type of liquid droplet adhere to a recording medium, an irradiator which irradiates electromagnetic waves individually onto the droplets, an irradiation controller which makes the irradiator irradiate the electromagnetic waves periodically, and a frequency setting unit which sets a frequency of an irradiation period to a first frequency such that surface glossiness of the first-type liquid droplet is equal to or higher than a predetermined threshold value, and sets a frequency of the irradiation period to a second frequency which is different from the first frequency such that surface glossiness of the second-type liquid droplet is lower than the threshold value.
