20100116164 | Method for Adjusting an Inking Unit of a Printing Press - A method is used for adapting an inking unit of a printing press. During a setup phase for the printing press, at least a first actual value with regard to an ink application that is set at the inking unit and that is applied to the printed material, is determined by use of a first measuring device. The inking unit is initially set using this first actual value. During continuous printing of the printing press, a plurality of second actual values, with respect to a printed image formed on the printed materials, are determined using a second measuring device which is different from the first measuring device. These second values are fed to an ink adapting device for the inking unit. At least one of these several actual values, which corresponds to the setting mode in the setting phase, is set in the ink adjusting device as its setpoint value. The ink adjusting device detects deviations of the other second actual values for this setpoint value and adjusts the inking unit to minimize these deviations. | 05-13-2010 |
20100189311 | Method for controlling the quality of printed documents based on pattern matching - A method for controlling the quality of printed documents, such as banknotes, in which only part of the surface of the printed documents is available for inspection, comprising the steps of (i) storing a reference image; (ii) acquiring a sample image of a sample printed document to be controlled, which sample image covers only a limited portion of the sample printed document; (iii) selecting a search pattern within the acquired sample image; (iv) searching the reference image for a match with the selected search pattern, (v) determining control parameters linked to the position of the search pattern within said sample image and within said reference image, (vi) comparing the control parameters linked to the position of the search pattern within the sample image with the control parameters linked to the position of the search pattern within the reference image; and (vii) based on the results of the comparison of the control parameters, accepting or rejecting the sample printed document. | 07-29-2010 |
20130319269 | COLOR CONTROL PATTERN FOR THE OPTICAL MEASUREMENT OF COLORS PRINTED ON A SHEET OR WEB SUBSTRATE BY MEANS OF A MULTICOLOR PRINTING PRESS AND USES THEREOF - There is described a color control pattern (CP) for the optical measurement of colors printed on a sheet or web substrate (S) by means of a multicolor printing press, especially by means of a multicolor security printing press, which substrate (S) a exhibits an effective printed region (EF) having a multicolor printed image comprising a plurality of juxtaposed colored areas (A-H) printed with a corresponding plurality of printing inks of different colors, wherein the color control pattern (CP) is located in a margin portion (Im) of the substrate (S) next to the effective printed region (EF). The color control pattern (CP) comprises one or more color control strips (a-d) extending transversely to a direction of transport (T) of the substrate (S), each color control strip (a-d) comprising a plurality of distinct color control fields (CF, CF | 12-05-2013 |
20140147029 | METHOD AND SYSTEM FOR TOUCHLESS COUNTING OF STACKED SUBSTRATES, ESPECIALLY BUNDLED BANKNOTES - There is described a method for touchless counting of substantially planar substrates, especially banknotes, which are stacked in the form of stacks of substrates, said method comprising the following steps: taking at least one sample image of a portion of a side of a stack of substrates, which sample image contains contrast information representing substrate edges that extend along substantially a first direction in the sample image; processing the contrast information representing the substrate edges within the sample image ( | 05-29-2014 |
20140218502 | INSPECTION SYSTEM FOR IN-LINE INSPECTION OF PRINTED MATERIAL PRODUCED ON AN INTAGLIO PRINTING PRESS - There is described an inspection system ( | 08-07-2014 |
20150040785 | DEVICE FOR OFFLINE INSPECTION AND COLOR MEASUREMENT OF PRINTED SHEETS FOR THE PRODUCTION OF BANKNOTES AND LIKE PRINTED SECURITIES - There is described a device ( | 02-12-2015 |
