Patent number: 11921454Abstract: A digital printing system (10) includes a flexible substrate (44), an optical assembly (200, 301) and a processor (20). The flexible substrate (44) has a periodic pattern, and is configured to be moved and to receive ink droplets in a printing process that forms an image thereon. The optical assembly (200, 301) is configured to illuminate the flexible substrate (44) with light (215, 315), to detect the light (215, 315) from the flexible substrate (44), and to derive from the detected light (215, 315) a signal indicative of the periodic pattern. The processor (20) is configured to receive the signal and to monitor or control the digital printing system (10) based on the periodic pattern as indicated by the signal.Type: GrantFiled: September 2, 2020Date of Patent: March 5, 2024Assignee: LANDA CORPORATION LTD.Inventor: Vitaly Burkatovsky

Patent number: 11833814Abstract: Printing apparatus (20) includes a continuous blanket (24) and a set of motorized rollers (31), which advance the blanket at constant speed through an image area. Print bars (38) eject droplets of ink at respective locations onto the blanket in the image area. Monitoring rollers (42), in proximity to the locations of the print bars, contact the blanket to be rotated by blanket advancement. Each monitoring roller includes an encoder (44), which outputs a signal indicative of a rotation angle of the monitoring roller. A control unit (40) collects, during a calibration phase, the signal from the encoders over multiple rotations of the monitoring rollers, detects a deviation of the signal from the encoder relative to a clock signal having a predefined frequency, and computes runout correction factors. During an operational phase, the control unit applies the runout correction factors to synchronize the droplets ejection from the print bars.Type: GrantFiled: October 11, 2022Date of Patent: December 5, 2023Assignee: LANDA CORPORATION LTD.Inventor: Vitaly Burkatovsky
