This invention discloses an offset printing press for printing securities, which includes an offset printing unit, inspection camera unit, and sheet quality determination unit. The offset printing unit prints a ground tint pattern on a transported paper sheet. The inspection camera unit is arranged upstream of the offset printing unit in the direction in which the paper sheet is transported, and captures an image of the paper sheet. The sheet quality determination unit determines the quality of the paper sheet based on image data output from the inspection camera unit.

A display device which is connected, in data terms, to a printing press, is controlled. A depiction of a printed image, which is printed onto a printing material by the printing press, together with a plurality of ink zones, arranged next to one another transversely, with respect to a transport direction of the printing material which is guiding through the printing press, of at least one inking unit, which is arranged in the printing press, are indicated on a display surface of the display device of a control unit in a controlled manner. The inking zones are indicated by way of parallel boundary lines, which delimit them in each case. For the display of the boundary lines which delimit the inking zones, the control unit fixes one of the color thereof and the brightness thereof and the opaqueness thereof in a manner which is dependent on a minimum contrast which has previously been set in the control unit, in order to form an image region, adjoining the boundary lines, of the printed image which is displayed on the image surface of the display device and displays the boundary lines which delimit the inking zones in the contrast ratio which is fixed in respect of the printed image which is displayed on the display surface of the display device.

A system including a non-contact plate sensor and a processor configured to characterize a configuration of a plate based upon information received from the sensor, such as position on a press or plate quality. The processor is configured to initiate a responsive action based upon the characterized configuration. A related method includes setting pressure of a printing plate relative to an ink-receiving substrate and register of a printing plate relative to another printing plate on a press, without generating printed waste. The non-contact plate sensor measures a distance of the printing surface of the plate relative to the sensor in locations along the plate longitudinal axis to characterize a starting configuration of the plate. The plate longitudinal axis is adjusted to correspond with a desired position of the plate for exerting a desired pressure on the substrate, based upon a difference between the measured starting position and the desired position.

Methods, systems, and non-transitory memory media embodying computer readable instructions for minimizing voids in front of a trailing edge of a solid rendition or linework print region printed using a photocurable flexographic printing plate having a printing surface corresponding to information in an image file. At least one solid rendition or linework image region corresponding to the solid rendition or linework print region has a pattern of on and off single pixels that correspond to openings formed by an imager in a mask layer of the plate. Micro-screen openings in an edge region of the solid rendition or linework mask region are imaged with a different size than micro-screen openings in a center region of the solid rendition or linework mask region.

A display device which is connected, in data terms, to a printing press, is controlled. A depiction of a printed image, which is printed onto a printing material by the printing press, together with a plurality of ink zones, arranged next to one another transversely, with respect to a transport direction of the printing material which is guiding through the printing press, of at least one inking unit, which is arranged in the printing press, are indicated on a display surface of the display device of a control unit in a controlled manner. The inking zones are indicated by way of parallel boundary lines, which delimit them in each case. For the display of the boundary lines which delimit the inking zones, the control unit fixes one of the color thereof and the brightness thereof and the opaqueness thereof in a manner which is dependent on a minimum contrast which has previously been set in the control unit, in order to form an image region, adjoining the boundary lines, of the printed image which is displayed on the image surface of the display device and displays the boundary lines which delimit the inking zones in the contrast ratio which is fixed in respect of the printed image which is displayed on the display surface of the display device.

A method of testing a functional unit includes an optical sensor system (28) for detecting an optical signal from at least a part of a moving material web (14), a data processing system (36) for valuating the optical signals, and a display (38) displaying a state of the material web (14) and arranged in a sensitive range (30) of the sensor system (28).

A control station of a printing machine has at least one surface for receiving a sheet-like printing substrate, a measuring device for measuring a measurement variable of the sheet-like printing substrate on the surface, at least one camera for capturing at least one gesture performed by a person at the control station, and an image-processing device for processing and evaluating images captured by the camera. The measuring device has a measuring beam extending above the sheet-like printing substrate. The measuring beam of the measuring device can be moved over the sheet-type printing substrate on the surface.
