The effect of air resistance acting on ink drops discharged from nozzles of an ink-jet head is appropriately controlled, for example, by means of a method suitable for a breathable medium, such as a cloth and the like. In this way, for example, high-resolution printing, printing with a great gap distance, and the like is properly implemented.An ink-jet printer 10, for printing on a breathable medium 50 through which air passes from a printing surface to a rear surface, includes an ink-jet head 12 for discharging ink drops toward the medium 50, and a rear side component 14, having a hollow portion that opens its space toward the rear surface of the medium 50; and then ink-jet head 12 includes nozzles for discharging ink drops to the medium 50, and an airflow blowing section for blowing airflow, at least a part of the airflow going through a travel path of the ink drops, and the airflow moving toward the medium 50 together with the ink drops; and the rear side component 14 receives the airflow, passing through from the printing surface of the medium 50 to the rear surface of the same, with the hollow portion.

(Problem to be Solved)To appropriately restrain occurrence of striped variation and to appropriately enhance image quality of a printed result.(Solution)An inkjet printer in which multi-gradation printing is performed in an inkjet method includes an ejection control section for controlling ejection of ink droplets by supplying an ejection control signal to a nozzle for controlling ejection of the ink droplets from the nozzle of an inkjet head. The inkjet head forms lines of ink dots juxtaposed in a line direction so that the lines are juxtaposed in a direction perpendicular to the line direction. In a case that a nozzle which forms a line is the abnormal nozzle, an ejection control signal corresponding to an ink dot size which is different from a case of the normal nozzle is supplied as the ejection control signal corresponding to a part of the dots juxtaposed in the line, thereby an average value in the line of ejection errors is brought close to zero.

Disclosed is a printing method whereby a glossy image free of running can be printed by an inkjet printer. An inkjet head (14) is caused to scan in the Y direction to print outline portions (32 and 33) on a medium (31). Next, immediately after the printing of the outline portions, a first UV irradiation means (15 or 16) disposed coaxially with the scanning axis of the inkjet head irradiates ink at the outline portions with UV light to harden the ink at the outline portions to prevent running. Next, the inkjet head prints a solid portion (34) between the outline portion (32) and the outline portion (33), and a second UV irradiation means (17) disposed forward in the scanning direction (X direction) of the medium (31) hardens the ink at the solid portion.

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.

A bulk ink supply system of an inkjet printer includes a connector, an ink flow path, and an on-off valve. The connector is attachable to and detachable from an ink container. The connector includes an ink guiding path formed in the connector. The ink flow path connects the ink guiding path and an inkjet head of the inkjet printer to supply an ink from the ink guiding path to the inkjet head. The on-off valve allows communication between the ink guiding path and the ink flow path when the ink container is attached to the connector and hinders communication between the ink guiding path and the ink flow path when the ink container is detached from the connector.

A printer apparatus includes a guide rail, a first device including a first head, a second device including a second head, and a hauling device including a driving member movable between the first device and the second device. A first holding mechanism is provided on one side with respect to a medium supporter. A second holding mechanism is provided on another side with respect to the medium supporter. When ink is to be ejected from the first head, the second holding mechanism holds the second device separated from the driving member, and a first connecting mechanism connects the first device to the driving member. When ink is to be ejected from the second head, the first holding mechanism holds the first device separated from the driving member, and a second connecting mechanism connects the second device to the driving member.

A UVLED (62) or a UVLED array unit (64) is employed in the UV-ray emitting body of a UV-ray irradiating means (60) for curing a UV-ink drop, shot at the surface of print media (50) mounted on a platen (20) from the ink jet head (30) of an ink jet, by irradiating it with UV-rays. Power consumption of the UV-ray irradiating means (60) is suppressed greatly, the UV-ray irradiating means (60) is reduced in size and weight or simplified, waiting time of the UV-ray irradiating means (60) is eliminated when the UV-ray emitting body is lighting, or generation of ozone is prevented when the UV-ray emitting body is lighting.
