A method for compensation for a failed print nozzle of an inkjet printhead for the printing of a printed image onto a print material conveyed in a transport direction, includes printing the printed image with at least two different print droplet volumes, one of which is a maximum print droplet volume. At least one compensation nozzle, i.e. a neighboring nozzle of the failed nozzle, prints compensation droplets with an elevated compensation droplet volume compared to the maximum print droplet volume. A frequency for the creation of compensation droplets is defined, and the compensation nozzle is actuated such that the defined frequency is observed and the successive compensation droplets printed by the compensation nozzle have a defined minimum separation in the transport direction.

A screen-printing cylinder includes a cylinder shell and one or more flexible surface elements on the cylinder shell. The one or more flexible surface elements are at least one of resilient or springy, and the one or more flexible surface elements are elliptical patches or circular patches. The flexible surface elements give way upon contact with sheet grippers projecting from an impression cylinder, so that it is not necessary to move the screen-printing cylinder out to avoid contact with the sheet grippers.
A printing system for rotary screen printing includes a screen-printing cylinder having flexible surface elements. The flexible surface elements give way upon contact with sheet grippers projecting from an impression cylinder, so that it is not necessary to move the screen-printing cylinder out to avoid contact with the sheet grippers. A screen-printing cylinder, a method for producing a screen-printing cylinder, a printing machine and a method for using a screen-printing cylinder, are also provided.
A printing screen includes a screen-shaped fabric layer with fabric threads being angled relative to one another to form a carrier layer. An imaged stencil layer is connected to the fabric layer and provided with passages. A respective passage forms a continuous channel and has an opening that is smaller on a printing material side of the printing screen than on a squeegee side of the printing screen. Such a printing screen has sufficient stability and advantageously allows the finest lines and dots to be printed. A method for imaging such a printing screen is also provided.

The invention relates to a screen printing stencil with at least one screen-like woven fabric layer (1) with woven fabric strands (6) which are arranged at an angle with respect to one another as carrier structure and with an imaged stencil layer (2), wherein the stencil layer (2) and the woven fabric layer (1) are connected to one another, and wherein the stencil layer (2) is provided with passages (3): according to the invention, a respective passage (3) has a smaller opening (9) on the printing material side (4) of the screen printing stencil (10) than on the squeegee side (5) of the screen printing stencil (10) and forms a continuous channel. A screen printing stencil (10) of this type has sufficient stability and advantageously makes it possible to print very fine lines and/or dots. The invention also relates to a method for imaging a screen printing stencil of this type.

A flat screen material for use in screen printing has strands forming a woven screen structure. The strands are arranged at angles to one another and crossing at crossing points, where the strands form undercuts there, and otherwise forming a screen structure with openings and metal deposits, at least at the surfaces thereof, deposited onto the strands in an electroplating process. The undercuts, in the area of crossing points of the strands, at least to some extent have a filling, made of the metal, that has been applied in the electroplating process. The filling, in particular, forms an inner-edge transition with rounding. The fillings improve the properties of the screen material, particularly with regard to stability, through-flow and possible cleaning. A screen for rotary screen printing is made of such a flat screen material.

The invention relates to a flat screen material (1) for use in screen printing, having strands (5, 5.1, 5.2) forming a woven screen structure, said strands being arranged at an angle to each other and crossing at intersection points (10), wherein at said intersection points the strands (5, 5.1, 5.2) form undercuts (11) and otherwise form a screen structure having openings and, at least at the surfaces thereof, consist of metal (3) which was deposited on the strands (5, 5.1, 5.2) in a galvanising process. According to the invention, in the region of the intersection points of the strands (5, 5.1, 5.2), the undercuts (11) thereof have at least in some cases a filling (12) of the metal applied during the galvanising process. This filling can form in particular an inner edge-transition with a rounding (12.1). The fillings improve the properties of the screen material in particular in respect of stability, flow-through and cleaning options. The invention also relates to a screen (4) for rotary screen printing made of such a flat screen material (1).
A printing press (1) comprises a cylinder (3) with a cylinder axle (5) and a cylinder channel (4). The cylinder axle (5) is supported on a first roller (11.1) and a second roller (12.1). The first roller (11.1) and the second roller (12.1) are loaded by a spring (18).
