Abstract: Some examples include checking the quality of printed products that are consecutively produced by multiple printing presses to have at least three printed patterns spaced apart from one another. The printed patterns are printed using different printing processes, such as a steel engraving process, an offset printing process, and a screen printing process that may be used for printing the three printed patterns of each printed product. A screen printing press is used for the screen printing process, with multiple steel plates being alternately used in the same production operation for the steel engraving process in an intaglio printing press. For at least two of the steel plates involved in carrying out the steel engraving process, a processing unit may selectively ascertain the deviation of the respective value of the relevant distances associated with the printed patterns, which may be instantaneously ascertained from a defined scale.

Abstract: A photographic image captured by a camera of an inspection system is manipulated. The photographic image captured by the camera is optically displayed on a screen which is a controller and a touch-sensitive screen surface. The controller displays a position-variable operating element with a mounting device on the screen. An object, with an object surface area with less than one millimeter square, is selected on any position and photographic image displayed on the screen, such that the marking device of the operating element is positioned at the position of the selected image by changing the position of the operating element. The control which is triggered by the positioning process of the marking device of the operating element, activates a manipulation tool. The selected object is manipulated independently of the rest of the photographic image displayed on the screen by use of the manipulation tool.

Abstract: The invention relates to a method for determining the isomer composition in an isocyanate isomer mixture, wherein a spectrum of the isomer mixture is recorded and the spectrum is entered into a chemometric calibration model.
