The object is to obtain a printed product excellent in fastness to washing. To achieve the object, a printing method is provided. The printing method includes a forming step of forming a solvent UV ink layer () on a printing target object (), a drying step of drying the solvent UV ink layer (), a decorating step of forming a decorative layer () on the dried solvent UV ink layer (), and a curing step of curing the decorated solvent UV ink layer () by irradiating the same with ultraviolet.

Printing method and printed product

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

Generation of cockling is suppressed to enable superior image quality printing. An inkjet printing device is provided with a head discharging ultraviolet curing ink onto a medium, pinning irradiation sections irradiating the ultraviolet curing ink on the medium with light, and a curing irradiation section arranged on a downstream side of the pinning irradiation sections in a conveying direction of the medium, and radiating light with a shorter wavelength than the pinning irradiation sections.

The problem addressed by the present invention lies in obtaining printed material having higher brightness using an ultraviolet-curing metallic ink. In order to solve this problem, the printing method includes: an ink ejection process, in which an ultraviolet curing type metallic ink including metal particles is ejected on a recording medium, and the recording medium is swelled by the metallic ink, soaked with the metallic ink, or dissolved by the metallic ink; a leveling process, in which the metallic ink on the recording medium is leveled; a temporary curing process, in which ultraviolet rays are irradiated to the metallic ink on the recording medium to cure in such a degree that the metallic ink is not completely cured; and a main curing process, in which ultraviolet rays are irradiated to the metallic ink on the recording medium for curing after the temporary curing process.

Printing method

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.
