Publication number: 20240075762Abstract: A method including receiving a first signal indicative of a first electrical current measured on a first motion assembly (77) for moving a flexible substrate (44) that receives droplets of a printing fluid from an image forming station (60) to form an image thereon. A second signal indicative of a second electrical current measured on a second motion assembly (99) for moving the flexible substrate (44), is received, wherein a section of the flexible substrate (44) is moving between the first motion assembly (77) and the second motion assembly (99). A parameter, which is indicative of a distortion in the image, is calculated based on the first signal and the second signal. In response to detecting, based on the parameter, an increase in the distortion, a corrective action is applied to reduce the distortion.Type: ApplicationFiled: January 16, 2022Publication date: March 7, 2024Inventors: Igal Ben-Dayan, Almog Koren, Ittai Wiener, Yevgeny Zakharin

Publication number: 20220388300Abstract: An impression station of a printing system comprises a rotatable impression cylinder with an impression cylinder gap housing a plurality of grippers recessed therein. A pressure cylinder assembly comprises a pressure cylinder comprising a pressure cylinder gap and an angle portion joining a trailing edge of the pressure cylinder gap and an outer circumferential surface of the pressure cylinder. A compressible blanket is disposed around the circumference of the pressure cylinder. A margin insert is interposed between the pressure cylinder and the compressible blanket at least at the angle portion, such that a local external geometry of the pressure cylinder assembly at the angle portion is changed by the presence of the margin insert. The change in the local external geometry of the pressure cylinder assembly due to the presence of the margin insert is effective to reduce a dimension of an unprinted leading-edge margin.Type: ApplicationFiled: May 22, 2022Publication date: December 8, 2022Inventors: Avshalom LEAN, Ittai WIENER, Matan BAR-ON

Patent number: 8839718Abstract: A method of error correction in a printing system includes engaging a sheet of print media with a perfector arm and detecting a relative position of the perfecter arm with respect to the sheet of print media when the perfecter arm has engaged the sheet of print media, the detecting being performed using a homing sensor that is configured to sense the perfecter arm while the perfecter arm is engaged with the sheet of print media. The relative position of the perfecter arm with respect to the sheet of print media is compared with an expected relative position and any difference between the relative position and expected relative position is compensated for when feeding the sheet of print media with the perfector arm to a print engine.Type: GrantFiled: March 25, 2009Date of Patent: September 23, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ittai Wiener, Dima Vais, Maxim Bramnik, Israel Lasker, Ayal Galili, Alex Feygelman
