Abstract: A method and system for implementation of quality control includes a machine vision system for capturing images of instances of a product, and a computer system including computer memory containing machine-readable instructions executable by a processor. The processor evaluates the quality control images for a plurality of potential quality defects in the product and generates a defect alert associated with a captured image in which at least one potential quality defect is identified. Information about each defect alert is stored in a database log file in the computer memory. A neural network machine learning algorithm processes the database log file by, in a learning phase, receiving human-initiated input accepting or rejecting each defect alert and storing the human-initiated input in the log file, and, in an automated phase, automatically accepting or rejecting at least some defect alerts without performing the step of receiving human initiated input.

Abstract: A system and method for controlling registration between different printing plates or printing cylinders in a printing press which includes a camera with a lens having at least two zoom settings and a control unit for changing the zoom setting of the camera in accordance with a distance between registration marks printed on a printed substrate found in at least one image acquired by the camera.

Abstract: A method for inspecting a surface of a printing medium, the method comprising the steps of acquiring an image of the surface or a portion thereof, digitizing the acquired image whereby a digitized real representation of the surface or portion is obtained.

Abstract: A method for color measurement and control and a color measurement and control system for determining during printing, on-press, the color value of at least one location on a printed substrate. The color measurement and control system includes a camera for acquiring an image of an area of the printed substrate, a color measurement device for measuring a color value of a location of the printed substrate, the color measurement device and the camera are operating substantially simultaneously, and a processing unit for receiving the image captured by the camera and the color measurement and for providing a position of the location with respect to the image employing the image itself. The processing unit is also operative to provide a color value of a desired position, the desired position is selected from the determined position and a position other than the determined position.
