Abstract: A device for locating a moving glass support is described. A conveyor roller surface is arranged to generate movement of the glass support. The device illuminates the glass support and acquires a plurality of lines of the moving glass support. A primary image is generated as a function of the acquired plurality of lines. A plurality of representative points of the glass support are detected from the primary image. Location coordinates of the glass support are calculated as a function of the plurality of representative points. A system for printing on the glass support inclusive of the locating device is further described.

Abstract: An image identification method for printing on rigid substrates includes the steps of: defining a digital graphic design representative of a rigid substrate to be produced; spreading a soft layer of granular or powder ceramic material on a deposition surface; pressing the soft layer to obtain a compacted layer; acquiring a real image of the compacted layer, detecting keypoints of the real image; comparing the keypoints of the real image with keypoints of an image obtained or derived from the digital graphic design; and calculating a portion of the digital graphic design corresponding to a portion of the real image. An image identification system for printing implementing the described method and a corresponding printing method/system are also described.
