Some examples include checking the quality of printed products that are consecutively produced by multiple printing presses to have at least three printed patterns spaced apart from one another. The printed patterns are printed using different printing processes, such as a steel engraving process, an offset printing process, and a screen printing process that may be used for printing the three printed patterns of each printed product. A screen printing press is used for the screen printing process, with multiple steel plates being alternately used in the same production operation for the steel engraving process in an intaglio printing press. For at least two of the steel plates involved in carrying out the steel engraving process, a processing unit may selectively ascertain the deviation of the respective value of the relevant distances associated with the printed patterns, which may be instantaneously ascertained from a defined scale.

Multiple ones of the protection fields are encompassed by a next-larger and/or next-wider protection field, entirely or at least viewed in the width and toward the top. The scan images of the two scanners are checked for a breach of the relevant protection fields in differing, adjoining, or overlapping partial regions of the plane. Information about the permissibility of a determined protection field breach is derived by evaluation of breach patterns of breached protection fields obtained in the two partial regions.

Abstract

In some examples, photographic mapping of an object takes place during transport at a fixed position by means of a line camera in a sequence of recording periods. An exposure device is exposed for an exposure time that is dependent on the duration of the on-time of the line camera. Each strip-shaped portion of the object to be photographically mapped is exposed, within a recording period, asynchronously for the duration of a first exposure time to white light and for the duration of a second exposure time either to ultraviolet light or to IR light. Each strip-shaped portion of the print image to be photographically mapped is alternately exposed by the exposure device, within the recording period photographically mapping the portion, to white light and either to UV light or to IR light during the duration of the on-time of the line camera.

Abstract

A method for separating printed products, that are printed together onto a sheet of printed products, is disclosed. The printed products are printed onto a sheet in a printing press and are separated in a cutting system by a cutting device. Each of these printed products has an identification feature that identifies its respective position on the sheet. The sheet becomes deformed as it passes through the printing press. The separated printed products, which are likewise deformed, as a result of the deformation of the sheet, are inspected, in a quality control device which is located downstream of the cutting system, for compliance with the tolerance, at least with regard to the respective length or width of the printed products. For each printed product that has been identified, in terms of its position, the quality control device detects information relating to an exceeding of the tolerance, at least for the length or width of the printed product, and transmits that information, assigning that information to the position identified on the sheet, to a control unit of the cutting system. Based on the information transmitted by the quality control device, for printed products that are arranged in the same position on the sheet, and which will subsequently be separated in the cutting system, the control unit of the cutting system adjusts the relevant sheet and the cutting device in their respective positions, relative to one another, in such a way that each of the printed products to be separated complies with the respective tolerance. Compliance with the tolerance is achieved in that the position of the sheet and of the cutting device to be adjusted relative to one another is calculated in the control unit using a mathematical optimization method. The sheet is placed on a cutting table in the cutting system. The control unit of the cutting system adjusts the position of the sheet relative to the cutting device, according to the calculated position.

Abstract

The invention relates to a drying unit (22) for drying printed substrates (21), comprising a chamber (23) with a gaseous medium which is oxygen-reduced by means of an inert gas, wherein the substrates (21) are guided through the chamber (23) or at least can be guided through the chamber, and the chamber (23) has an entrance for the substrates (21) to be guided into the chamber (23) in the transport direction (T) of the substrates (21). The entrance for the substrates (21) to be guided into the chamber (23) is formed by two cylinders (04; 06) which are positioned against each other longitudinally. The cylinders (04; 06) positioned against each other at the entrance of the chamber (23) form a printing unit (03). One of the cylinders (04) is designed as a printing cylinder (04), and the other cylinder (06) is designed as a cylinder (06) which interacts with the printing cylinder (04) and applies a printed image onto the affected substrates (21). The two cylinders (04; 06) which are positioned against each other under pressure at the entrance of the chamber (23) form a seal which runs axially to the cylinders (04; 06) for preventing the oxygen-reduced gaseous medium from leaking out of the chamber (23) and/or for preventing oxygen from the ambient air from entering the chamber (23). The printing unit (03) arranged at the entrance of the chamber (23) is designed as a printing unit (03) for an intaglio printing process.

Abstract

A method is provided for printing a surface of a non-absorbent substrate with an ink to be applied by an inkjet printing device. An ink that contains water as a solvent is used for printing the substrate. An ink having a water content of at least 70% is used. The substrate to be printed is supported by a workpiece support and is moved relative to the inkjet printing device. During this relative movement, ink is applied by the inkjet printing device to the surface of the substrate to be printed. The ink that is applied to the surface of the substrate is heated to a temperature that is above the temperature of the air surrounding the substrate and that is below the boiling point of the solvent contained in the ink. Above a liquid phase of the ink, a vapor layer, consisting of the solvent that is contained in the ink, is formed. The vapor layer that is formed above the liquid phase of the ink is transported away by an air flow emitted by at least one blower nozzle unit. The air output by the respective blower nozzle unit is heated or is dehumidified beforehand. A digital printing press is provided for carrying out this method.

Abstract

A method is provided for setting a layer thickness of a covering coating material to be applied to a substrate by an application device. The coating material is applied to the substrate in a printing machine or in a paper-processing machine. The coating material is applied at various points on the substrate by the use of the application device in a machine process. At each of at least one first point on the substrate, the coating material is applied in a grid having a plurality of grid points, and at each of at least one other second point on the substrate, the coating material is applied over the full area. Each first point on the substrate forms a grid zone and each second point on the substrate forms a solid zone. A control unit connected to a sensing device determines respective values of the optical density of the layer of the coating material applied on the points on the substrate using data captured by the sensing device at the first and second points on the substrate. The control unit defines the layer thickness of the coating material currently applied to the substrate by the application device in an ongoing machine process. At the defined thickness, the value of the optical density determined in a grid zone corresponds to the value of the optical density determined in a solid zone, as the layer thickness of the coating material having an opacity of 100%.

Abstract

A screen-printing unit in a printing machine comprises a screen cylinder which carries a screen-printing stencil and in which a squeegee is moved, from the inside, into contact with, and away from the screen-printing stencil. The screen cylinder is moved into contact with an impression cylinder, such that a printing position is formed, and is moved away therefrom, such that a gap is formed. The screen cylinder is moved away from the impression cylinder, in a first phase, when the squeegee is in a non-contacting position. In a second phase, at least one sheet of printing material is passed through the printing position when the squeegee continues to be in a non-contacting position and the screen cylinder is at least temporarily in a contacting position. For subsequent sheets of printing material, in a third phase, the screen-printing unit is operated with the squeegee one of permanently and cyclically, such as at least once for each sheet of printing material, in a contacting position.
