摘要： The invention relates to a method for profiling a print medium for use in a printing system. The print medium is received in an input holder and a plurality of test jobs is received in a test job receiver. For each test job a uniquely determined combination of at least a first printing system parameter of print speed of the printing system and a second printing system parameter of coverage of the marking material is intended to be prepared by a print controller. The printing system registers a test result of each test job. The print controller creates a two-dimensional media print mode table of media print modes for the print medium to be profiled based on the test results of the test jobs for the print medium. When a print job arrives intended to be printed on the profiled medium, a media print mode is selected from the two- dimensional media print mode table.

摘要： The present invention relates to an aqueous pre-treatment liquid for use in ink jet printing, the pre-treatment liquid comprising: water; magnesium-sulfate; and a crystallization retarding agent selected from the group consisting of: sorbitol, xylitol, adonitol, β-alanine, proline and γ-aminobutyric acid. The pre-treatment liquid is non¬ yellowing, non-smelling and does not crystallize upon drying. Prints made by using a pre-treatment liquid according to the present invention in combination with an aqueous ink shows a significant decrease of end-curl after a long period of time.

摘要： A compact fluid distribution device (130) for a print head assembly (100) is provided, which device allows for the effective removal of gas from the device during operation and purging. The device comprises a fluid chamber (131) with a fluid permeable filter (132) forming a dividing wall in the fluid chamber, such that an inlet (137) is positioned on a first side of the filter and the outlet (135) is positioned on a second side of the filter. The filter is inclined with respect to a first direction parallel to a vertical direction during operation, such that a first volume in the fluid chamber between the filter and a first side wall facing the filter tapers in a direction away from the inlet.

摘要： The present invention relates to an air impingement module for an inkjet printer. The air impingement module for an inkjet printer comprises a plate for creating an array of air beams comprising a plurality of impingement holes. Further, the air impingement module for an inkjet printer comprises a width adjustment arrangement for blocking the array of air beams of the air impingement modules in a direction (z) substantially perpendicular to the transport direction of a printing substrate (y) and substantially perpendicular to the normal to the plane of the surface of a printing substrate (x) which is also the impingement direction, such that the array of air beams are restricted to a particular width, and such that directions x, y, and z form a substantially orthogonal axes system.
