Abstract: In a method for fixing a print good in a printing system, the print good is a substrate printed to with ink, and the print speed of the print good is initially determined. Air heated to a predetermined temperature is then blown onto the print good. The heated air is supplied with a volumetric flow rate that is adjusted depending on the print speed.

Abstract: A printing device includes an applicator with which a test fluid is applied onto a recording medium to be printed to, as well as an absorption measurement system with which absorption data are acquired with regard to the absorption rate of the test fluid. The printing device also includes a fuser to fix a print image printed by the printing device. The fuser is adjusted depending on the acquired absorption data so that an optimal and/or desired fixing of print images on the respectively used type of recording medium is produced.

Abstract: In a method for fixing a print image on a recording medium, data is determined for controlling one or more radiation sources to fix the print image. The data can be determined based on a deformation model of the recording medium such that a deformation of the recording medium is reduced or minimized.

Abstract: A roller for transferring a print image or a toner layer onto another element in a printer or copier is provided. The roller can include a base body, a first elastic layer applied onto the base body and a second elastic layer applied onto the first elastic layer, wherein the ratio of the moduli of elasticity of the elastic layers and/or the ratio of the thicknesses of the elastic layers are matched to one another so that the average surface velocity difference between the roller and the other element is reduced and/or minimized.

Abstract: A method and a controller operable to adjust the field strength of an electrical field for the toner transfer in an electrographic printing process. Current values of framework parameters can be determined and a control loop configured to adjust the electrical field is adapted based on current values of the framework parameters. An electrical reference variable of the control loop can be adapted to the current values of the framework parameters. The electrical reference variable can include, for example, a current and/or a voltage for the toner transfer.

Abstract: In a method to adjust print quality of print images in an electrophoretic digital printer with at least one print group, the print group generates charge images of the print images. The charge images are developed with a developer station into toner images using liquid developer having carrier fluid and toner. The toner images are transfer-printed onto a carrier medium in a transfer station. A first control marking is generated on the recording medium with elements of the first control marking being aligned transverse to a printing direction. A shape of the elements of the first control marking is measured to generate a first measurement signal. The first measurement signal is compared with a predetermined nominal value, and given a difference, an adjustment signal is generated via which an amount of the carrier fluid in the liquid developer is modified so that the first measurement signal approaches the predetermined nominal value.

Abstract: In a method or a transfer station for a digital printer, liquid developer with toner particles can be directed towards a first side of a recording medium and onto the first side of the recording medium at a transfer point. A transfer roller can be configured to direct the liquid developer towards the recording medium. The toner particles can have a first polarity and the recording medium can move past the transfer roller along a transport direction. A layer of charged particles can be applied from a second side of the recording medium by a surface charging station. The surface charging station can be arranged before the transfer point in the transport direction. The second side of the recording medium can be opposite the first side. The charged particles can have a second polarity that is opposite the first polarity.

Abstract: In a method, a computer program product and a system for conversion of an input document data stream with one or more documents into a structured data file, source data fields in an input document data stream are automatically positioned for readout of data to be extracted, whereby their positioning occurs by means of absolute or relative addressing. The source data fields are positioned by means of source data regions with which sections of the individual documents are detected. These source data regions are arranged nested and can in turn themselves be positioned absolutely or relatively. The corresponding rules are created in simple fashion via marking of the corresponding source data regions and source data fields in the template document.

Abstract: In a method or system for conversion of an input data document data stream that corresponds to one of many possible input data formats into an output document data stream that corresponds to one of many possible input data formats, the input document data stream is converted into an internal data format. Document formatting information that establishes a representation of the data in the output format is added as needed to the data in the internal data format. The data are then converted into the output data format.
