A recording device, when recording is performed on a predetermined type target recording medium stored in a storage unit, drives a surface potential adjustment unit so that a surface potential is a positive potential within a predetermined range. By configuring such a recording device, it is possible to suppress adhesion of ink to an ejecting unit, and occurrence of an ink ejection failure can be suppressed.

A liquid discharging apparatus includes: a discharging head configured to discharge an ultraviolet cure ink onto a recording medium; and a controller configured to control the discharging head to: discharge the ink onto the recording medium on the basis of a raster data for an image to be formed on the recording medium, the image including a solid image area formed with the raster data at 100% of a printing rate; and execute a gloss reduction printing in which the solid image area is printed on the recording medium by varying the printing rate such that printing rates lower than 100% appear along a printing direction periodically or aperiodically in the course of 100% printing rate.

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.

Printing machine, for printing a laminar web, comprising a feeding unit (10) defining a printing area (A); an inkjet printing station (20) comprising a plurality of inkjet printing modules (21) slidably arranged along a transverse guide (22); a positioning device (30) adapted to precisely slide the inkjet printing modules (21) along the transverse guide (22); wherein each inkjet printing module (21) includes a first coupling (31) and is independent from other inkjet printing modules (21) allowing an independent movement of each inkjet printing module (21) along the transverse guide (22); and the positioning device (30) includes a second coupling (32) complementary to each first coupling (31), the second coupling (32) being releasably engageable to each first coupling (31) in an automatic manner, the positioning device (30) being configured to precisely slide each inkjet printing module (21) engaged thereto, along the transverse guide (22).

A heating device includes a heater and a heating range variable member. The heater heats an object to which a liquid is applied. The object is conveyed in a conveyance direction. The heating range variable member changes a heating range of the heater in a width direction of the object. The width direction is orthogonal to the conveyance direction.

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.

An image forming apparatus includes a liquid discharge head, an irradiation unit, a carriage, and a moving unit. The liquid discharge head discharges a liquid onto a recording medium. The liquid includes a metallic ink and a color ink. The irradiation unit irradiates the liquid on the recording medium with light. The liquid discharge head and the irradiation unit are mounted on the carriage. The moving unit alternately perform a main scanning movement and a sub-scanning movement. The liquid discharge head discharges the metallic ink in a region of the recording medium in a former main scanning movement and discharges the color ink in the region in which the metallic ink has been discharged, in a latter main scanning movement after the former main scanning movement. The irradiation unit irradiates the region in which the color ink has been discharged with the light.

A light irradiator includes a light source, a heat-dissipating member thermally connected to the light source, a drive including a drive circuit for the light source, a housing having vents and an irradiation opening for light from the light source to pass, and a blower. The rectangular housing has a first surface having a first side with a first dimension and a second side with a second dimension, a second surface having the second side and a third side with a third dimension, and a third surface having the first and third sides. The opening is in the first surface. A first vent and a second vent are in the second surface, with the first vent nearer the opening, and the second vent opposite to the opening. The heat-dissipating member faces the first vent. The drive is between the first and second vents. The blower faces the second vent.

An image forming apparatus includes a liquid discharge head, an irradiation unit, a carriage, and a moving unit. The liquid discharge head discharges a liquid including a metallic ink and a color ink onto a recording medium. The irradiation unit irradiates the liquid on the recording medium with light. The liquid discharge head and the irradiation unit are mounted on the carriage. The moving unit perform a main scanning movement and a sub-scanning movement. The liquid discharge head discharges the metallic ink in a region of the recording medium in the main scanning movement and discharges the color ink in the region in which the metallic ink has been discharged, in the same main scanning movement in which the metallic ink is discharged. The irradiation unit irradiates the region in which the metallic ink and the color ink have been discharged, with the light in the same main scanning movement.

Disclosed is a method of controlling an inkjet printing process. According to one embodiment of the present invention, a method of controlling an inkjet printing process by using an inkjet print system, the method including a printing operation of moving a first support chuck or a second support chuck in a second direction perpendicular to a first direction and performing the inkjet printing process of discharging an ink onto a substrate and a first suction operation of suctioning remaining ink from a nozzle formed on a first head or a second head using a first suction unit, wherein a controller controls the printing operation for a first substrate, the first suction operation for the second head or the printing operation for a second substrate, and the first suction operation for the first head to be sequentially performed.
