The disclosure optimizes suction force. An inkjet printing apparatus (1) includes a suction table (2) having a placement surface (21a) for the medium (M); a blower (52) that generates a suction force on the placement surface (21a); and a control device (55) that controls a suction force generated by the blower (52). The control device (55) includes a switcher (553) that switches the suction force to generate, where when the medium (M) is placed on the placement surface (21a), the switcher (553) drives the blower (52) at a first output level to generate a first suction force, and suctions the medium (M) placed on the placement surface (21a). Thereafter, the blower (52) is driven at the second output level lower than the first output level to generate the second suction force weaker than the first suction force, thereby suctioning the medium M placed on the placement surface (21a).

The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.

A heating device heats a sheet to which a liquid discharge unit discharges a liquid. The heating device includes a first heater to heat the sheet that has passed through the liquid discharge unit, a vacuum conveyor to convey the sheet that has passed through the first heater while sucking the sheet, a second heater to heat the sheet being conveyed by the vacuum conveyor, and circuitry that cause the first heater to heat the sheet when sheet data regarding the sheet satisfies a predetermined condition.

Certain examples described herein relate to printing systems and methods of operating the same. In an example of a printing system, a porosity determiner determines a porosity of a print medium and a signal generator generates a signal relating to a state of a printing fluid collector based on the porosity determined. In an example of a method of operating a printing system, a pressure measurement is obtained from a vacuum system of the printing system when a print medium is present on a media path of the printing system. This is compared to at least one predefined pressure range and, based on the comparison, an indication is provided setting out a state of a printing fluid collector.

Provided in one example is a printing system. The system includes a printing zone including a platen (50). The system includes a drive to move a medium (58) through the printing zone. The system includes a suction force generator (78) to generate a suction force to hold down the medium onto the platen while the drive moves the medium through the printing zone. The system includes a sensor (52) to monitor the movement of the medium through the printing zone in a medium advance direction. The system includes a controller to determine that the suction force generated by the suction source generator is insufficient based on an output of the sensor.

Disclosed is a substrate treating apparatus. The substrate treating apparatus may include a stage including an accommodation area, onto or from which a substrate is loaded or unloaded, and a treatment area, in which the substrate is treated, a liquid discharge head that supplies a treatment liquid to the substrate, and a liquid receiving part that receives the treatment liquid pre-discharged by the liquid discharge head in the treatment area.

A method for manufacturing an architectural panel and an architectural panel made by the method. The architectural panel may be formed from metal, and the method may start with the processing of a flat metal sheet. The method may include punching holes in a particular pattern into the flat metal sheet, bending the flat metal sheet into a particular shape to form a panel that can be hung from an overhead grid or the like, and printing a desired printing pattern onto the panel. The method may also include a step of coating the panel with a powder coating or a liquid-applied paint finish prior to the printing step. The coating step may occur after the punching step and before the printing step.

An inkjet printing method on a continuous substrate web (100), having a pair of edges (1011, 1021), comprising the steps: a) forming a pair of elongated strips (101, 102) by bending said substrate web (100) along a pair of lines (1010, 1020) wherein each line is parallel to the pair of edges (1011, 1021); and b) supporting said bent substrate web in a support zone (201) of a printer (200) wherein said pair of elongated strips (101, 102) are oriented towards said zone (201); and printing an image (500) on said supported substrate web by an inkjet-printhead (202) of said printer (200).

A vacuum belt conveyor sequentially delivers sheet articles to a digital printer. The sheets are held in position by vacuum on the underside of the sheets through apertures in the belt and covered by the sheets. A plurality of independent plenums on the underside of the belt have chambers respectively communicating with rows of apertures extending along the belt. Vacuum is selectively applied from a manifold only to the plenum chambers that supply apertures that are covered by the sheets so that the ink from the printer will not be directed from its intended position on the sheet by vacuum from adjacent uncovered belt apertures.
