Abstract: A printing system and method for improving ink absorption in a print substrate by preventing evaporation includes a conditioned transport module arranged for transporting a printed print substrate from a (conditioned) image formation module to a drying/fixation module. The transport module includes a control system configured for controlling the relative humidity inside the transport module to at least 50%.

Abstract: A system and method for adding a print medium digitally to a print system are disclosed. The print system has a control unit for controlling a print job queue and print system parameters, a print engine, an input section, and a receiving section. The method includes receiving the print medium in the input section, loading a test job having prescribed print system parameters in the receiving section, printing a large number of prints of the test job to establish an unwanted deposit of marking material on the side of the stack, and establishing whether or not an unwanted marking material is deposited on a stack height side of the stack. If unwanted deposit is established, then printing a number of blank sheets of the same print medium, adjusting the print system parameters, and returning to printing. If no unwanted deposit is established, approving the use of the print medium.

Abstract: The present invention provides a method of optimizing the operating conditions for printing sheets, comprising the following steps: introducing a sheet into the printing system; treating the sheet by exposing the sheet to a physical operating condition of the printing system at a predetermined level; sensing a surface geometry of the exposed sheet to generate data representing a height map of the surface of the at least one exposed sheet for that predetermined level of that operating condition; and comparing the data to one another and/or a reference value to determine the suitable level of the least one physical operating condition. The invention further provides an apparatus optimizing the operating conditions for printing sheets.

Abstract: In a combination of an image forming apparatus and an apparatus for treating media sheets after an image has been formed, the image forming apparatus includes a processing stage causing the media sheets to be heated, and the apparatus for treating the media sheets is disposed on a discharge side of the image forming apparatus. The apparatus for treating media sheets includes a perforated conveying and support substrate arranged to convey the media sheets through a stabilization zone where the substrate has a limited curvature. A suction device applies a vacuum to the perforations of the substrate in the stabilization zone so as to suck the media sheets against the substrate. A cooling system is arranged for actively cooling the media sheets while they are sucked against the substrate in the stabilization zone.
