摘要： The quality of printed matter, which is one of several copies of the same printed matter produced by a printing machine, is evaluated. An amount of copies of the printed matter is selected from the total production of this printed matter. The selected amount of these copies are evaluated with regard to at least one error type which belongs to an amount of different error types or with regard to at least one feature of the error. Within the selected amount of copies, an error of a defined error type or of a defined feature, which is detected on at least one of the copies, is evaluated in relation to at least one error of another type or feature detected on the same copy, or another copy of the selected amount. The printed matter is classified as having good or bad quality based on that evaluation. A common reading, producing image data, is obtained by an image sensor from the selected copies. All of the errors to be evaluated in relation to each other are detected from image data gathered during the same common recording.

摘要： Color deviations of images are analyzed using a sensor. The received image sensor signal is analyzed pixel by pixel. An image sensor signal is produced for each color channel from a plurality of color channels. An image sensor signal from a first channel, and one from a second channel, are combined. An output signal of a first color contrast channel is generated. Now an image sensor signal from a third channel is combined with the ones from the first and second image sensors. An output signal of a second color contrast channel is generated. The outputs of these color contrast channels are classified.

摘要： At least one register and an ink density are controlled in a printing machine having at least one printing unit which includes a forme cylinder, a transfer cylinder, and a counter-pressure cylinder. An image sensor records an image from a print substrate, which is imprinted with ink, inside the printing unit, and sends data correlated to that image to an evaluation unit. The data for the last printed image is compared with prior data and in response, the evaluation unit generates a command that is directed to an actuator for controlling the supply of ink. The image sensor is oriented towards the print substrate and detects the entire width of the printed substrate, which width is transverse to a direction of substrate conveyance. The evaluation unit generates the actuating command to control the supply of ink based on data from the image sensor and taken over the entire width of the substrate. The evaluation unit also controls register, based on this data. The forme cylinder has a separate drive which can be controlled separately or that can be regulated by the counter-pressure cylinder assigned to it.

摘要： The image data of a camera system is corrected. The camera system includes a color camera which supplies three output signals to three separate color channels, in the form of output signal vectors. The output signal vectors, the coefficients of which represent the output signals supplied by the color camera to the three color channels in a specific position lying in the range of observation, are multiplied by a correction matrix, particularly a square one. The corrected output signal vectors are then processed further in the camera system.

摘要： A material, with at least one identification characteristic, is subjected to a qualitative evaluation. A color image of this at least one identification characteristic is taken using an electronic image sensor which produces an electrical signal that is evaluated by an evaluation device. Another electrical signal is obtained from at least one reference image and is stored in a data memory. The second electric signal, has a set point value, for the first electric signal, for at least two set point values contained in the reference image. The first signal is compared to at least two set point values in the second image. The color image of the identification characteristic is tested for deviation from the reference. The identification characteristic is checked for association with at least one aspect of the identification characteristic of the material. The tasks are carried out in a continuous working process being carried out by a machine, such as a printing machine, during a continuous printing process.

摘要： There is described a method for detection of occurrence of printing errors on printed substrates during processing thereof on a printing press comprising the steps of providing multiple sensors on functional components of the printing press to monitor the behavior of the printing press during processing of the printed substrates and performing an in-line analysis of the behavior of the printing press to determine occurrence of a characteristic behavior of the printing press which leads or is likely to lead to occurrence of printing errors on the printed substrates or which leads or is likely to lead to good printing quality of the printed substrates. In-line analysis of the behavior of the printing press preferably includes performing fuzzy pattern classification of the behavior of the printing press. According to one embodiment of the proposed method in-line analysis of the behavior of the printing press is coupled with an in-line optical inspection of the printed substrates.

摘要： There is described a method for checking the authenticity of security documents, in particular banknotes, wherein authentic security documents comprise security features (41-49; 30; 10; 51, 52) printed, applied or otherwise provided on the security documents, which security features comprise characteristic visual features intrinsic to the processes used for producing the security documents. The method comprises the step of digitally processing a sample image of at least one region of interest (R.o.I.) of the surface of a candidate document to be authenticated, which region of interest encompasses at least part of the security features, the digital processing including performing a decomposition of the sample image by means of wavelet transform (WT) of the sample image. Such decomposition of the sample image is based on a wavelet packet transform (WPT) of the sample image, preferably a so-called two-dimensional shift invariant WPT (2D-SIWPT)
