An ultraviolet curing ink can be sufficiently leveled, and attachment of, for example, dust can be prevented. In an ink-jet printer, a carriage capable of reciprocating in a scanning direction is mounted with an ink-jet head for ejecting a color ink and a clear ink and ultraviolet irradiation devices for emitting ultraviolet rays. A control unit performs control so that in the forward movement of the carriage, a color ink is ejected and applied to a medium, and in the backward movement of the carriage, ultraviolet rays are irradiated to the color ink deposited on the medium and the color ink is cured. Subsequently, the medium is fed in a feed direction, and the clear ink is ejected and applied to the surface of the cured color ink in the forward movement of the carriage. In the backward movement of the carriage, the clear ink applied to the medium is irradiated by ultraviolet rays and is cured.

Device and method for forming image

An inkjet printer includes a guide rail that faces a medium support member and extends in a scanning direction. A head device includes a carriage movable in the scanning direction along the guide rail. A printer head is mounted on the carriage and is configured to discharge an ink toward a printing medium. An ultraviolet radiation device is mounted on the carriage and is configured to output an ultraviolet radiation toward the printing medium thereby curing the ink that has adhered onto the printing medium after being discharged from the printer head. The ultraviolet radiation device is arranged in the carriage on a side of the printer head in the scanning direction. An intensity controller is configured to control an intensity of the ultraviolet radiation output from the ultraviolet radiation device depending on a direction of movement of the carriage.

Inkjet printer and method for printing

An ink jet printer includes a medium supporter to support a print medium. A print head is configured to eject ink droplets toward the print medium. An ultraviolet light irradiation device is configured to irradiate the print medium with ultraviolet light to cure ink deposited on the print medium. On a carriage, the print head and the ultraviolet light irradiation device are mounted to face the medium supporter. The carriage is reciprocally movable relative to the print medium in a first direction and movable relative to the print medium in a second direction perpendicular to the first direction. The ultraviolet light irradiation device is arranged on a side in the first direction of the print head. The print head is arranged to project toward an upstream side of a feeding direction in the second direction by a predetermined length relative to the ultraviolet light irradiation device.

Inkjet printer and printing method using the same

An inkjet printer including an inkjet head unit having inkjet heads for ejecting UV inks, an UVLED unit having a UVLED for emitting ultraviolet light, and a control unit for controlling the inkjet head unit and the UVLED unit. The control unit controls the inkjet head unit and the UVLED unit to move in the scanning direction, controls the inkjet heads to eject UV inks, and controls the UVLED to emit ultraviolet light of a first light quantity. After that, the control unit controls the inkjet head unit and the UVLED unit to move in the direction opposite to the scanning direction and controls the UVLED to emit ultraviolet light of a second light quantity.

Inkjet printer and printing method

An ultraviolet curing inkjet printer includes a first ejecting device, a first ultraviolet light irradiation device, and a second ultraviolet light irradiation device. The first ultraviolet light irradiation device is configured to emit ultraviolet light of a first light quantity for temporarily curing the ultraviolet curable inks ejected from the first ejecting device. The first ultraviolet light irradiation device is disposed posterior to the first ejecting device in a first direction as a scanning direction. The second ultraviolet light irradiation device is configured to emit ultraviolet light of a second light quantity for finally curing the ultraviolet curable inks temporarily cured by the first ultraviolet light irradiation device. The second ultraviolet light irradiation device is disposed anterior to the first ejecting device in a second direction, which is perpendicular to the first direction and is a moving direction of a recording medium relative to the first ejecting device.

Ultraviolet curing inkjet printer, printing method used in ultraviolet curing inkjet printer, and head

An inkjet printer including a UVLED unit which emits ultraviolet light to a print medium supported on a supporting table to cure UV ink droplets deposited on the print medium. The inkjet printer further includes a controller which adjust the light quantity of ultraviolet light, emitted from the UVLED unit to the UV ink droplets deposited on the print medium, from a light quantity for temporary curing to a light quantity for final curing, and a control unit capable of selecting between a two-stage curing mode in which UV ink droplets deposited on the print medium are temporarily cured ant are then finally cured and a single-stage curing mode in which UV ink droplets are finally cured by an irradiation with ultraviolet light at one time by means of the UVLED unit and the controller.
