Definitions
- the invention relates to methods for identifying a single benefit with a print image of faulty quality on a substrate with multiple benefits according to the preamble of claim 1 or 11.
- the DE 200 10 920 U1 and the EP 11 67 036 A1 are a printing machine, in particular a sheetfed offset press, known in which for detecting the quality of a printing material arranged on an image capture device detects the substrate and an evaluation device connected to the image acquisition device compares the recorded by the image capture device image of the substrate with a reference image, wherein the substrate with a A plurality of identical printed images is printed and the evaluation evaluates only a subset of the printed images from the image of the printing material, wherein the evaluation outputs a signal to a counter for registration of the subset in accordance with the evaluated subset with the reference image.
- a method of identifying a single benefit with a print image of defective quality on a multi-use substrate wherein an inspection system with a camera captures an image of the substrate and processes data of the captured image in an image processing system, the image processing system capturing the data of the image processing system recorded image with a single benefit on the substrate compares data record.
- an image inspection system for a printing press in which the printing material printed in the user recorded by an image pickup device and the image signals obtained are processed in a downstream image processing, wherein the image pickup device is arranged according to the image signals controllable printing device, through which at designated locations of the printing material markings can be generated for the identification of identified as defective areas, as a result of which incorrectly printed benefits are ausschleusbar in a suitably trained device further processing.
- the invention has for its object to provide methods for identifying a single benefit with a print image of faulty quality on a substrate with multiple benefits, where the identification of the print image of defective quality benefits without the aid of a printed Referenzbedruckstoffes takes place and in which for the identification of individual erroneous benefits and for obtaining a record for performing this identification a rational production process results.
- a printing material printed by a printing press in particular a sheet
- the benefit with the print image of faulty quality is separable in a subsequent process of the printing process, so that all other benefits can be fed with a print image of good quality of the intended use.
- a single benefit with a printed image of defective quality is uniquely identifiable. It is very advantageous that each of the proposed methods is capable of identifying individual benefits of any shape and orientation on the substrate.
- a set-up phase of the printing press remains unaffected by the process for identifying a single benefit with a print image of faulty quality, so that in the setup phase of the printing press, an additional step is not required, the z. B. could consist in an evaluation of a specially prepared Einrichtebogens.
- a suitable in particular for a print image inspection inspection system has according to its schematic representation in the Fig. 1 a camera 01, z. B. one or more coupled color line cameras 01 or a color area camera 01, which receives an illuminated by a lighting device 02 image of a preferably formed as a sheet 03 substrate 03 after the z. B. made of paper substrate 03 from a printing press, z.
- a rotary printing machine in particular a sheet offset rotary printing machine, has been printed with at least one printed image.
- the printing material 03 is printed in its passage through the printing press in multi-color printing, so involved in the production of the printed product several superimposed to be printed, differing in hue of the respective printing ink color separations.
- the image taken by the camera 01 forms at least part of the printing material 03.
- the output of the result is z. B. on a connected to the data processing image processing system 04 monitor 06.
- inputs, z. B. the image processing system 04 for its calculations necessarily be notified parameters are entered via a connected to the image processing system 04 keyboard 07.
- the substrate 03 here z. B. the sheet 03 is printed in its passage through the printing press in the whotik and has according to the Fig. 2 several individual benefits 09 in a composite.
- the individual benefits 09 may be repetitive, z. B. also identical print motifs, preferably structured, z. B. grid-like, ie arranged in rows and columns, on the sheet 03, wherein arranged on the sheet 03 benefits 09 in the preferred embodiment does not have to cover the entire printable area of the sheet 03.
- the benefits 09 arranged on the sheet 03 are identical in their contours, or for the respective contours to be substantially rectangular, or for those arranged on the sheet 03 Benefits 09 are adjacent to each other seamlessly or that the benefits 09 are arranged on the sheet 03 in a regular structure, ie a grid with a fixed orientation.
- the sheet 03 resulting on the sheet 03 at least one area 11, z.
- the printed sheet 03 further processing process step is removed. Therefore, the image photographically taken by the color line camera 01 or the color area camera 01 from the sheet 03 in the image processing system 04 is preferably evaluated only with respect to the utility 09 arranged on the sheet 03, so that the area 11 or edge 11 located on the sheet 03 outside the utility 09 one of the quality of the printed image mitigating error is not evaluated.
- the selective evaluation of the sheet 03 with respect to at least one of the quality of the printed image mitigating error eg. As a color error, contamination or any other before or especially during the printing process the bow 03 added error is designed such that it is determined which arranged on the sheet 03 benefits 09 of the color line camera 01 or the color surface camera 01 detected error is to be assigned.
- information about the location of the detected error with respect to the surface predetermined by the sheet 03, in particular its printable surface is preferably initially determined in the image processing system 04 by a corresponding evaluation of the data correlated with the recorded image, so that the quality of the printed image is reduced Error z. B. is localized in its coordinates, and then of the printed on the sheet 03 benefits 09 of the benefits 09 is identified within the contour of the location of the detected error is located.
- a single benefit 09 is identified by the fact that the image processing system 04, so to speak, hangs up a template in its data processing process steps on the image taken by the color line camera 01 or the color area camera 01 from the sheet 03, the template consisting of an electronically generated data record, this data record is not taken from a photographically recorded image and in particular is not obtained within the printing press, but z. B. stored in a pre-press data is taken.
- the template forming the record is z. B. generated with a CAD system (computer-aided design) and a memory z. B. fed in the prepress, this record information about position, shape or shape or size, z. B. diameter, the individual arranged on the sheet 03 benefits 09 contains or wherein this information is at least removed from this record.
- the information can also refer to the arrangement of individual benefits 09 in the totality of all benefits 09 and thus provide information about the location of a single benefit 09 relative to one or more other benefits 09.
- the shape of a benefit 09 characterizes its type or type, e.g. As circle, rectangle or any other geometric shape.
- the data set is generated in conjunction with a production of a die for separating the benefits 09 from the sheet 03 and fed to the image processing system 04. This measure is advantageous because it makes use of an already existing data record, so that additional expenditure for generating this data record does not arise.
- the template forming the record is a fixed reference between a detected by the color line camera 01 or the color area camera 01 error to a single use 09 on the sheet 03 produced by the information z. B.
- the arrangement, shape or size of the individual arranged on the sheet 03 benefits 09 is superimposed on the data from the color line camera 01 or the color area camera 01 image or at least the information on the location of the detected error for the purpose of comparison. Because with the help of the template forming the record can now z. B. by the image processing system 04 by comparing the information to the determined location of the error with the information on the arrangement, shape or size of the individual arranged on the sheet 03 benefits 09 are clearly identified, which arranged on the sheet 03 benefits 09 a on the Sheet 03 is associated with detected and localized error.
- a benefit 09 identified in such a way with regard to a fault detected by the color line camera 01 or the color area camera 01 can be detected by a user.
- the identified on the sheet 03 benefits 09 within the contour of which is detected by the color line camera 01 or the color surface camera 01 error is separable from the other benefits 09 in a process subsequent to the actual printing process processing by arranged on the sheet 03 benefits 09 z , B. are punched out with a punch and the detected error having, preferably marked benefits 09 z. B. is extracted by discharge.
- all the benefits arranged on the sheet 03 are 09 except for the marked ones Benefit 09 of the intended use fed, which is particularly advantageous for high-quality printed products.
