An inkjet printer includes an ink head, a carriage, and a first discharge controller. The ink head discharges photo-curable ink onto a recording medium. The ink head includes a colored ink nozzle group to discharge colored photo-curable ink, and a transparent ink nozzle group to discharge transparent photo-curable ink. The carriage is equipped with the ink head. The first discharge controller is configured or programmed to, when either one of the carriage and the recording medium makes a single movement, cause the colored ink nozzle group and the transparent ink nozzle group to discharge the colored photo-curable ink and the transparent photo-curable ink, respectively, onto a predetermined region so as to form a colored image and a texture image. The texture image includes the colored photo-curable ink and the transparent photo-curable ink that overlap with each other.

A printer includes a controller to exercise control so as to print a print layer on or over a medium. The print layer includes a first print region including first protrusions, and a second print region including second protrusions. Any one or more of a size, a height, a planar shape, an arrangement interval, and an arrangement direction of the first protrusions is/are different from a corresponding one or more of a size, a height, a planar shape, an arrangement interval, and an arrangement direction of the second protrusions. An extracted area of about 3 cm by about 3 cm is extracted from any location in the print layer. The first and second print regions are in the extracted area. At least either a number of first print regions or a number of second print regions in the extracted area is more than one.

Printer, printed matter, and printing method

In a light radiation device including an upstream radiation portion, a middle radiation portion and a downstream radiation portion, the upstream radiation portion overlaps a nozzle array in a transportation direction. A controller includes a path controller to control a path operation of ejecting ink from the nozzle array onto a medium while moving a recording head and the light radiation device in a scanning direction, a transportation controller to control a transportation operation of, after the path operation, transporting the medium downstream in the transportation direction by a distance shorter than a length in the transportation direction of the nozzle array, and a first light radiation controller to control the light radiation device, during the path operation by the path controller, to turn on the upstream radiation portion and the downstream radiation portion and to turn off the middle radiation portion.

Printing device including light radiation device with independently controlled radiation portions

An inkjet printer includes a first light applicator disposed in a second scanning direction relative to a recording head. The first light applicator includes a first upstream light source group at a location corresponding to a location of the recording head in a movement direction of a recording medium, and a first downstream light source group on a downstream side in the movement direction of the recording medium relative to the recording head. The inkjet printer turns off the first upstream light source group and turns on the first downstream light source group during movement of a carriage in a first scanning direction and discharge of first ink from the recording head, and turns on the first upstream light source group and the first downstream light source group during movement of the carriage in the second scanning direction after discharge of the first ink.

Inkjet printer

A pointer includes a case housing an LED device and including a light emission hole through which light from the device is emitted to an external space, a first plate between the device and the light emission hole and including a first light passage hole that allows passage of the light from the device, and a second plate between the first plate and the light emission hole and including a second light passage hole that allows passage of the light having passed through the first light passage hole. The light passage holes and the light emission hole are located on a central axis of the device. The device and the first and second plates are disposed such that H/2&#x3c;S&#x3c;H, where H denotes a distance between the device and the first plate, and S denotes a distance between the first and second plates.

Pointer and inkjet printer including pointer

A printer can comprise a supporting wall that extends in a primary scanning direction, a table that is positioned lower than the supporting wall and that is structured so as to be able to move in a secondary scanning direction, a guide rail equipped on the supporting wall that extends in the primary scanning direction, a head carriage that is provided slidably on the guide rail and that can move in the primary scanning direction, an ink head mounted on the head carriage, and a partitioning wall that is positioned lower than the supporting wall and to a side of the table in the primary scanning direction and that extends in the secondary scanning direction and the vertical direction. When the table is positioned at the maximally downstream position along the secondary scanning direction, the upstream end portion of the table is positioned further downstream of the supporting wall and further upstream than the downstream end portion of the partitioning wall.

A printing apparatus includes a feeder that feeds a medium in a feeding direction, a head including a row of nozzles arranged side by side in the feeding direction and movable in a scanning direction, an irradiator that radiates light onto a region longer in the feeding direction than the nozzle row and that is movable in the scanning direction together with the head, and a controller that alternatingly causes the head to move in the scanning direction and concurrently the nozzles to discharge ink while causing the irradiator to radiate the light, and the feeder to feed the medium in the feeding direction. The controller is capable of dividing the nozzle row into an upstream-side nozzle row and a downstream-side nozzle row located on a downstream side in the feeding direction from the upstream-side nozzle row, and individually controlling discharge of ink from the nozzles of each of the upstream-side nozzle row and the downstream-side nozzle row. The controller is capable of dividing the irradiator into an upstream-side irradiator, an intermediate irradiator adjacent to the upstream-side irradiator on a downstream side in the feeding direction, and a printless region irradiator adjacent to the intermediate irradiator on a downstream side in the feeding direction, and individually controlling lighting and extinguishing of each of the irradiators defined by the division.

Printing apparatus

A printer includes a platen on which a recording medium is placed, an ink head movable in a main scanning direction and able to eject ink onto the recording medium, a cover disposed above and to at least a side of the platen and including an opening located downstream of the ink head in a subscanning direction, a front cover attached to the cover and able to open and close the opening, and an air blower disposed on the front cover.

Ink jet printer

A printer includes a first controller to cause a primer discharge head to discharge, from its nozzle, primer onto a recording medium and then cause a first ultraviolet light applicator to apply ultraviolet light to the primer, thus forming a first primer layer on the recording medium; a second controller to cause the primer discharge head to discharge, from its nozzle, the primer onto the first primer layer and the recording medium and then cause a second ultraviolet light applicator to apply ultraviolet light to the primer, thus forming a second primer layer on the first primer layer and the recording medium; and a third controller to cause an ink discharge head to discharge, from its nozzle, image-forming ink onto the second primer layer and then cause the first ultraviolet light applicator to apply ultraviolet light to the image-forming ink, thus forming an ink layer on the second primer layer.
