Provided is an evacuation device for an inkjet printing device that is designed to guide a printed recording medium along a transport direction through a constriction with an opposite gas flow, in order to be able to efficiently and comprehensively evacuate ink vapor before the constriction, in terms of the transport direction.

Device and method for evacuation of ink vapor

Thermal energy is supplied to a fluid mixture on a substrate that has a first component, for example water, and a second component, for example cosolvent, such that the proportion of the second component in the fluid mixture is increased at relatively high temperatures of the fluid mixture. It may thus be reliably produced that an optimally small quantity of the second component is located on the surface of the substrate following the drying process.

Method and dryer system for drying a fluid mixture

In a method for electrographic printing of color images on a final image carrier, charge images of images to be printed are generated on a charge image carrier and are developed into toner images with toner, the toner images being transferred onto an intermediate carrier from which they are transfer-printed onto the final image carrier. The charge images for individual colors of the color image are generated in succession on the charge image carrier and are developed into individual color toner images with color toner. The individual color toner images are transferred onto the intermediate carrier and are there collected atop of one another in a color collection cycle to form a complete color toner image. Before transfer printing of the complete color toner image on the final image carrier, the final image carrier is pivoted onto the intermediate carrier, and after the transfer printing, the final image carrier is pivoted away from the intermediate carrier. After transfer printing of the complete color toner image, the color toner images for a next complete color image are transferred from the charge image carrier onto the intermediate carrier after an end of the pivoting of the final image carrier away from the intermediate carrier.

Method for preventing the influence of the transfer of vibrations during the printing of images on a final image carrier

In a method to determine a curve of revolution speed of a continuous belt-shaped image substrate, at least two color separations are generated on the image substrate and transferred from the image substrate onto a substrate material to generate a print image. A first offset in a transport direction of the substrate material between the at least two color separations of the print image is determined at a first point. At least one second offset in the transport direction is determined between the at least two color separations of the print image at least one second point. The first point and the second point have at least one interval relative to one another in the transport direction. The curve of the revolution speed of the image substrate is determined with aid of the first offset and the second offset.

Method and assembly for generating a given revolving speed of an endless band-shaped image support

In a method and a system for generation of print images on a carrier material, an actual speed difference is generated in a transfer printing region between an image carrier and the carrier material. A deviation of the actual speed difference from a desired speed difference is determined with aid of a measurement arrangement.

Method and device for detection of the speed difference between an image carrier and a carrier material

The invention relates to a method and an arrangement for generating positionally-accurate print images on a carrier material with the aid of an electrophotographic printer or copier. A positioning error of the position of the carrier material with respect to a toner image present on the toner image carrier is determined, which error occurs during the contacting of a carrier material to be printed. Dependent on the positioning error determined, for every subsequent contacting of the carrier material to be printed with the toner image carrier, the position of the carrier material with respect to the toner image is adapted before the contacting such that the carrier material and the toner image are arranged with respect to one another substantially free of positioning errors.
