  • Patent number: 10894435
    Abstract: The present invention provides a method for printing a Quality Assurance print chart, QA chart, comprising the steps of: determining the maximum print width for at least one media sheet to be printed subsequently to the printing of the QA chart, selecting from a plurality of media types designated as being suitable for QA charts, a media type that has substantially the same or a greater media width as the determined print width for the at least one media sheet to be printed subsequently, setting a print width for the QA chart substantially to the determined print width, and printing the QA chart with the set print width on the selected media type.

  • Publication number: 20210014379
    Abstract: A duplex printing method includes, determining an amount of shrinkage of a media sheet onto which a front side image has been printed; scaling an image to be printed on a back side of the sheet with a scaling function that depends upon the determined shrinkage; and printing the scaled image on the back side of the sheet. The step of determining includes predicting a shrinkage of a media sheet on the basis of process parameters, and on the basis of a model that is defined by a set of model parameters and that describes a dependence of the shrinkage on the process parameters, the process parameters including at least an amount of marking material to be applied to the front side of the sheet; measuring an actual shrinkage of the sheet; and adjusting the model parameters based on a comparison between the predicted shrinkage and the measured shrinkage to improve a prediction of a shrinkage for a subsequent sheet.
