Abstract
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.
Claims26
A digital printing system, comprising:
- a flexible substrate comprising a fabric having first and second sets of fibers interleaved with one another in accordance with a periodic pattern, wherein the flexible substrate is configured to be moved and to receive ink droplets in a printing process that forms an image thereon;
- an optical assembly, which is configured to illuminate the flexible substrate with light, to detect the light from the flexible substrate and to derive from the detected light a signal indicative of the periodic pattern from the interleaved first and second sets of fibers;
- and
- a processor, which is configured to receive the signal and to monitor or control the digital printing system based on the periodic pattern as indicated by the signal.
3-4. (canceled)
The system according to claim 41, wherein the first and second sets of fibers are laid out orthogonally to one another in accordance with the periodic pattern, and wherein the optical assembly is configured to derive the signal indicative of the periodic pattern from the orthogonal layout of the first and second sets of fibers.
The system according to claim 41, wherein the first set of fibers is laid out orthogonally to a movement axis of the flexible substrate in accordance with the periodic pattern, and wherein the optical assembly is configured to derive the signal indicative of the periodic pattern from the first set of fibers.
