Abstract: An indirect printing system is disclosed having an intermediate transfer member (ITM) in the form of an endless belt that circulates during operation to transport ink images from an image forming station. Ink images are deposited on an outer surface of the ITM by one or a plurality of print bars. At an impression station, the ink images are transferred from the outer surface of the ITM onto a printing substrate. In some embodiments, the outer surface of the ITM 20 is maintained within the image forming station at a predetermined distance from the one or each of the print bars 10, 12, 14 and 16 by means of a plurality of support rollers 11, 13, 15, 17 that have a common flat tangential plane and contact the inner surface of the ITM. In some embodiments, the inner surface of the ITM is attracted to the support rollers, the attraction being such that the area of contact between the ITM and each support roller is greater on the downstream side than the upstream side of the support roller, referenced to the direction of movement of the ITM.

Abstract: A printing system is described that has an intermediate transfer member in the form of a seamed endless belt for transporting an ink image from an image forming station, at which an ink image is deposited on the intermediate transfer member, to an impression station, where the ink image is transferred onto a printing substrate. The belt has along its edges formations of a greater thickness than the belt. The formations are received in channels to guide the belt and maintain the belt under lateral tension. Two drive members are provided, each located within a respective one of the channels. The two drive members are connected for movement in synchronism with one another and each has a respective laterally projecting gripper shaped for form locking engagement with the formations on a leading end of a strip from which the intermediate transfer member is to be formed. Rotation of the drive members during installation of a new intermediate transfer member serves to thread the strip through the printing system by pulling the strip from its leading end.

Abstract: Some embodiments relate to a method of measuring a magnitude of a yaw angle of print head(s) or of a supporting print-bar thereof relative to cross-print direction. In some embodiments, a 1D-representation (1D-rep) of an ink-calibration image is transformed into the frequency domain (e.g. by FFT) characterized by peak profile. The yaw angle magnitude may be computed from relative energies of a primary and secondary peak of the peak profile of the frequency domain.

Abstract: A method for correcting distortion in image printing, the method includes receiving a digital image acquired from a printed image including at least first and second colors. Based on the digital image, a first color image of the first color and a second color image of the second color are produced. A first distortion in the first color image and a second distortion in the second color image are estimated. One or more first pixel-shifts that, when applied to respective first pixels in the first color image, compensate for the estimated first distortion, are calculated for the first color image. One or more second pixel-shifts that, when applied to respective second pixels in the second color image, compensate for the estimated second distortion, are calculated for the second color image. A first corrected image is produced by applying the first pixel-shifts to the respective first pixels, and a second corrected image is produced by applying the second pixel-shifts to the respective second pixels. The first corrected image and the second corrected image are printed on a target substrate.

Abstract: A printing system for printing on a substrate, comprises a movable intermediate transfer member in the form of a flexible, substantially inextensible, belt guided to follow a closed path, an image forming station for depositing droplets of a liquid ink onto an outer surface of the belt to form an ink image, a drying station for drying the ink image on the belt to leave an ink residue film on the outer surface of the belt, first and second impression stations spaced from one another in the direction of movement of the belt, each impression station comprising an impression cylinder for supporting and transporting the substrate and a pressure cylinder carrying a compressible blanket for urging the belt against the substrate supported on the impression cylinder, and a transport system for transporting the substrate from the first impression station to the second impression station. The pressure cylinder of at least the first impression station is movable between a first position in which the belt is urged towards the impression cylinder to cause the residue film on the outer surface of the belt to be transferred onto the front side of the substrate supported on the impression cylinder, and a second position in which the belt is spaced from the impression cylinder to allow the ink image on the belt to pass through the first impression station and arrive intact at the second impression station for transfer onto the reverse side of the substrate supported on the second impression cylinder.
