The object of the present invention is to propose a novel device and a novel method to allow the transportation of printable substrates precisely, suited to substrates of various types, sizes and thicknesses. Furthermore, the invention is suited to printing machines that involve no contact with the substrate, such as inkjet printing machines.

A printer includes: an inkjet head configured to eject ink to a medium; a vacuum platen having a platen surface and suction holes, the platen surface extending along a transverse axis that intersects the conveyance direction and that spans across a first side and a second side of the printer, and the suction holes, the suction holes including a first suction hole; and a suction unit configured to produce a negative pressure within the suction holes; the first suction hole comprising a first opening and a second opening, the width of the second opening being less than the width of the first opening, and the first opening having a center along the transverse axis, the second opening having a center along the transverse axis, the center of the second opening being offset to the first side along the transverse axis from the center of the first opening.

An elastic body portion includes an inner circumferential portion and an outer circumferential portion which serves as an outer circumferential side with respect to the inner circumferential portion and a space portion between the inner circumferential portion and the outer circumferential portion, and a plurality of joining portions which join the inner circumferential portion and the outer circumferential portion to each other in the space portion, in which at least a portion of each of the joining portions has a curved shape, and in which the joining portions are each joined to the inner circumferential portion and the outer circumferential portion such that connecting portions between the joining portions and the inner circumferential portion and connecting portions between the joining portions and the outer circumferential portion do not form acute angles in the space portion.

In one example, a media support includes a sheet of suction cups in which each suction cup has a port through which air may be evacuated from the cup. In another example, a detachable cover for a vacuum table includes: a sheet having a flat front surface, a flat back surface and multiple suction cups arranged across the front surface of the sheet. Each suction cup has a port to the back surface of the sheet to connect to a corresponding vacuum hole in the table when the cover is attached to the table.

A rotary printing machine includes a printing cylinder, at least one clamping unit mounted on a printing surface of the printing cylinder, and a feeding control mechanism and an unloading control mechanism mounted to a lateral side of the printing cylinder for changing the clamping state of the clamping unit. When the clamping unit is moved to an unloading position, the unloading control mechanism can be operated to control the clamping unit to maintain a closed state, so that a workpiece can be brought by the printing cylinder to a feeding position again. Then, the feeding control mechanism can be operated to control the clamping unit at the feeding position to maintain a clamped state, so that printing can be repeated on the workpiece to form multiple layers of ink and create three-dimensional printed layers showing a specific visual effect.

A recording substrate treatment apparatus includes transporting mechanism for transporting a sheet of a recording substrate through a first chamber in the interior space of the recording substrate treatment apparatus; a first suction device arranged for removing a gaseous medium from the first chamber; and an impingement device, arranged for providing a first flow of the gaseous medium at the outer surface of the transporting mechanism. The first suction device is fluidly connected to the impingement device, such that in operation the impingement device receives a first flow of the gaseous medium from the first suction device. With this arrangement, the impingement flow is balanced with an air flow directly extracted from the first chamber of the recording substrate treatment apparatus. A printing system including such a recording substrate treatment apparatus and a method of drying a recording substrate using such a recording substrate recording apparatus are also disclosed.

A sheet-fed printing press includes a printing cylinder and a high-precision sensor system for monitoring a sheet run in the area of the printing cylinder. At least one gage, which is mounted on the printing cylinder, can be detected by the sensor system. It is particularly advantageous if the sensor system is configured to be self-calibrating. A method for calibrating a sensor system and a method for aligning a sensor system are also provided.

A printing machine and method for using the same, for printing seamless fabrics provided in tube form, the printing machine comprising a drum on which a tube of the fabric is fitted; and a print head placed in proximity to said drum to print onto the tube fabric as it rotates on the drum. The print head moves axially on the drum to advance the printing.

A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in sucession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.
