  • Publication number: 20230325128
    Abstract: Method for a printing system for processing a print job comprising the print data and the plurality of print job settings. Automatically an area of the recording medium is established that is deemed to be removed or made invisible during the at least one finishing action by a finisher. A digital object is retrieved from memory of the printer which is used for checking and monitoring at least one characterization of the desired end product. The print data are printed and also the digital object is printed at the automatically established area.

  • Patent number: 11186107
    Abstract: A printing method comprising the steps of: supplying media of a given media type to a printer; printing images onto the media in accordance with given print specifications and settings, thereby to obtain a print result; measuring a performance indicator that is representative of a property of the print result; and comparing the measured performance indicator to a corresponding target value, wherein the target value for said performance indicator is obtained from an actual or simulated production print process on media of the given media type; and in that a message is produced when the measured performance indicator deviates from the target value by more than a threshold value.

  • Patent number: 10369821
    Abstract: In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a “tight winding” printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.

  • Patent number: 10280023
    Abstract: The invention provides a web winding device for attaching a leading edge of a web to a take-up roller positioned at an end of a transport path. A guide device is rotatable around the roller axis of the take-up roller from a first to a second angular position. The first angular position is positioned adjacent the end of the transport path and the second angular position is positioned in a space between the transport path and the take-up roller. The guide device is arranged for: at the first angular position, pushing the leading edge of the web against the take-up roller; during rotation, holding the leading edge in pushing engagement with the take-up roller; and at the second angular position, guiding the leading edge between the web on the transport path and the take-up roller for attaching the leading edge to the take-up roller.

  • Publication number: 20180345682
    Abstract: In a method for applying an image onto a recording medium, a print can be created that has a gloss similar to the gloss of the recording medium. The method includes selecting a recording medium; determining the gloss level of the selected medium; selecting curing settings based on the determined gloss level; applying an image onto the recording medium by ejecting a predetermined pattern of droplets of ink onto the recording medium; and curing the ink according to the selected curing settings, thereby obtaining a cured image having the determined gloss level. A printer is configured for applying an image onto a recording medium according to the method.

  • Patent number: 9956797
    Abstract: A printing system comprises a first bearing support for a first media roll of a first print medium and a second bearing support for a second media roll of a second print medium. Said first and second bearing supports are spaced apart from one another. A first print transport path extends from the first bearing support from the first media roll to a main transport path of the printing system. A second print transport path extends from the second bearing support to the main transport path of the printing system. An attachment transport path extends between the first and the second bearing support. The attachment transport path allows both print media to be brought together and attached to one another. Thereby, a relatively stiffer medium may be attached as a leader section to a relatively weaker medium.
