Abstract: A method for setting the pressure of a printing station includes at least one cylinder, from acquired images of the printed area of the printed web. The method includes displacing the at least one cylinder in accordance with a pre-defined displacement scheme, and acquiring the acquired images of the web throughout the displacement of the at least one cylinder, for each of the at least one cylinder, determining according to the acquired images, a left side print distance and a right side print distance, and determining for the each of the at least one cylinder a left actuator working distance and a right actuator working distance for the left actuator and the right actuator, respectively, according to the left side print distance and according to the right side print distance.

Abstract: An inspection system of a printed substrate, the printed substrate at least includes a three-dimensional pattern, the system includes a light source, for emitting light beams toward the substrate, the light beams being substantially aligned when impinging on the substrate, an imager, for acquiring an image of the substrate, the image including a representation of the three-dimensional pattern and of the matter printed on the substrate and a processor, coupled with the light source and the imager, for processing the acquired image to determine the correctness of the three-dimensional pattern.
