Abstract: A planetary roller extruder for homogenizing, dispersing, pasteurizing, and purposefully controlling the temperature of biodegradable materials that are prone to altering their properties during processing, in particular the properties that rule out further use after the materials have been processed, such as food, medicinal products or pharmaceutical products, different regions being present in the planetary roller extruder. The planetary roller extruder includes a flow conduit having various transitions from one region to a next region in an interior and components being statically and movably installed. A seal is installed between statically installed components, by which seal gaps or cavities present are configured to be closed. A slide ring seal provides sealing between moving components, which are led from the flow conduit in the interior outward to a surrounding area, so as to avoid steps and/or notches along flow surfaces in a transition region of the moving components.

Abstract: A method for compensating tone value fluctuation in inkjet printing includes generating multi-bit halftone images of pixels on a computer during prepress screening for color separations with multiple tone values out of print image data, forwarding multi-bit halftone images to a control unit of an inkjet printing machine, and printing the multi-bit halftone on the machine, wherein encoded binary values of multi-bit halftone images correspond to ink drop sizes to be generated by the machine. The computer introduces additional binary values of multi-bit halftone images not corresponding to ink drop sizes in pixel positions of multi-bit halftone images where occurring tone value fluctuations are to be compensated for by modified ink drop sizes, causing additional binary values to be ignored by the machine in a regular print mode, and assigning additional binary values to modified ink drop sizes in a correction print mode.
