A liquid discharge apparatus includes a stage on which a recording medium is placed, a head configured to discharge a liquid onto the recording medium on the stage, an inclined wall adjacent to the recording medium, the inclined wall configured to cover a part of the stage, and a height adjuster configured to adjust a height of one end of the inclined wall to be equal to or lower than a thickness of the recording medium.

A printer includes a platen, a first head, a second head, and an illumination device. In a normal print mode, the first head, the second head, and the illumination device are moved relatively with respect to the platen in a main scanning direction, in a state in which a distance between the platen and a predetermined position of the illumination device in the height direction is a first distance, and the ink is ejected onto an object to be printed placed on the platen and the light is irradiated onto the ejected ink. In a gloss print mode, the first head, the second head, and the illumination device are moved relatively with respect to the platen in the main scanning direction, in a state in which the distance between the platen and the predetermined position in the height direction is a second distance larger than the first distance.

A printer includes a platen, a first head, a second head, a first lamp, and a second lamp. The first head, the second head, the first lamp, and the second lamp are moved relatively with respect to the platen in a main scanning direction, and the platen is moved from the second head toward the first head relatively with respect to the first head, the second head, the first lamp, and the second lamp, repeatedly. The second head ejects the second ink onto the object to be printed placed on the platen while the first head, the second head, the first lamp, and the second lamp are moving in the main scanning direction. The first lamp irradiates light onto the second ink on the object to be printed while the first head, the second head, the first lamp, and the second lamp are moving in the main scanning direction.

An apparatus is disclosed for printing images on generally cylindrical objects. The apparatus comprises an impression station that includes a movable imaging surface for bearing an ink image; and a transport mechanism for advancing the objects through the impression station, comprising a drive member rotatably connected to a plurality of rotatable mandrels, each for mounting a respective one of the objects, the transport mechanism being configured to cause each object to rotate during passage through the impression station such that, within a nip region of the impression station, the surface of the object makes rolling contact with the imaging surface, thereby causing the ink image to be impressed on the object. An impression platen is provided opposite the imaging surface within the nip region, the impression platen being configured to apply a force, directly or indirectly, to the objects to ensure rolling contact between the objects and the imaging surface.

The present disclosure relates to the technical field of printing, and provides a digital printing press. The digital printing press includes a frame, and an unwinder, a driver, an inkjet printer, a curer and a winder that are arranged on the frame, where the driver drives a substrate to move from the unwinder to the winder along a substrate path, the inkjet printer and the curer are arranged above a printing segment of the substrate path, the printing segment of the substrate path is in the shape of an arch, and the arch bends toward the inkjet printer and the curer. The UV light from the curer can be reflected by the substrate to a position other than the inkjet printer as a result of the arched printing segment. UV light is prevented from entering the inkjet printer's nozzle, extending the inkjet printer's service life.

A three-dimensional object printing method includes first operation of concurrently performing ejection of liquid toward a workpiece by a head, emission of energy toward the workpiece by an energy emitter, and movement of the head and the energy emitter with respect to the workpiece by a moving mechanism, and second operation of concurrently performing emission of energy toward the workpiece by the energy emitter and movement of the head and the energy emitter with respect to the workpiece by the moving mechanism, without performing ejection of liquid by the head. A first irradiation distance, which is a distance between the workpiece and an emission face during execution of the first operation, and a second irradiation distance, which is a distance between the workpiece and the emission face during execution of the second operation, are different from each other.

A printing apparatus includes an ejection head including a first nozzle row configured to eject, toward a recording medium, a first liquid containing a photopolymerization initiator and a second nozzle row configured to eject, toward the recording medium, a second liquid containing the polymerizable compound and a color material and not containing the photopolymerization initiator, a driving unit configured to change relative positions of the ejection head and the recording medium, and an irradiation unit configured to irradiate, with the light, the recording medium onto which the first liquid and the second liquid are deposited. The first liquid and the second liquid are ejected from the ejection head so that the second liquid overlaps the first liquid on a surface of the recording medium. A distance between the irradiation unit and the first nozzle row is longer than a distance between the irradiation unit and the second nozzle row.

There is provided an ultraviolet ray irradiating apparatus configured to cure an ultraviolet-curable ink discharged to an object, by a discharging head which is configured to move in a main scanning direction, in a state that the ultraviolet ray irradiating apparatus is moved in the main scanning direction. The ultraviolet ray irradiating apparatus includes a plurality of light emitting chips configured to emit an ultraviolet ray, the plurality of light emitting chips being arranged side by side with a first pitch in the main scanning direction and being arranged side by side with a second pitch smaller than the first pitch in a sub scanning direction orthogonal to the main scanning direction.

There is provided a printer including a head configured to discharge a liquid onto a printing surface of a printing medium, the liquid being curable by applying energy; an energy applying unit; a moving device which relatively moves the head and the energy applying unit with respect to the printing medium; and a controller. The controller executes discharge of the liquid from the head onto the printing surface while relatively moving the head and the printing medium; application of first energy and second energy from the energy applying unit to the liquid, while relatively moving the energy applying unit and the printing medium; and decision of an added-up energy amount of the first energy applied to the liquid on the printing surface from the energy applying unit until the second energy is applied after the application of the first energy depending on a state of the printing surface.

A printer includes a head, a lamp, a first sensor, and a processor. The head is configured to eject photocurable ink onto the object to be printed supported by a platen. The lamp is configured to irradiate light onto the object to be printed on which the ink is ejected. The first sensor is provided inside the printer, and is configured to detect a temperature inside the printer. The processor causes the first sensor to acquire the temperature inside the printer. The processor acquires, based on the print data, a duty ratio indicating a printing ratio when ejecting the ink onto an ejection region of the object to be printed. The processor sets an illuminance of the light irradiated by the lamp, based on the temperature acquired by the first sensor and the acquired duty ratio.
