Definitions

  • the present invention relates to a method for identifying printed products in print processing according to the preamble of claim 1.
  • a collating machine which separates and merges printed sheets forming a book block from a large number of magazines.
  • image recognition is provided, which checks the read image of an isolated layer. To do this, the read image is compared with a previously taught-in target image.
  • the disadvantage here is that the target image is generated by reading in several identical layers of the following production order in the gathering machine during set-up. The layers to be taught must be fed manually to the magazine in the correct orientation. On the one hand, such a process is not possible for individual products and only possible to a very limited extent for very small runs.
  • teaching in is very complex and error-prone due to the manual intervention.
  • the volume of data to be processed from the image information is considerable and restricts the production output or requires correspondingly powerful data processing.
  • EP 1 715 441 A2 discloses the preamble of claim 1.
  • the paper or another printable material is provided with an optically detectable printed image on one or more of its outer surfaces by printing methods in a known manner.
  • This printed image can be visually recorded in such a way that it is visible to people without aids. However, it can also be partially or completely invisible to humans, for example by containing colors outside the visible color spectrum.
  • This printed image contains image information used as an identification feature.
  • This identification feature allows the printed product to be identified in such a way that it can be clearly assigned to a respective production order. For this purpose, a usable area of the originally applied printed image is used as an identification feature. This means that there is no need for an additional mark applied for further processing to identify the printed product, such as a barcode or data matrix code that detracts from the aesthetic appearance.
  • the identification feature is divided into two or more non-contiguous areas that are spaced apart from each other. Image sections of the print image and in one form within these areas. The areas are defined by their arrangement and their extent. In accordance with the definition of the image sections forming the identification feature, the image information to be processed for the identification is greatly reduced compared to the recorded printed image. This reduces the time required for the transmission and processing of the required information without impairing the functional reliability of the identification.
  • the expression of the identification feature is characterized by an optical property such as contrast, brightness, color value, saturation or pattern or by a
  • the printed product is fed to a device for print further processing in order to be further processed by it. It is irrelevant whether the printing unit and the device for post-print processing are connected to one another in the sense of inline production or whether there is a separation between printing and post-processing, for example by storing the printed products in an interim storage facility.
  • the device for further print processing uses a suitable reading device to capture that printed image of the supplied printed product which contains the identification feature.
  • a suitable reading device to capture that printed image of the supplied printed product which contains the identification feature.
  • this is a digital camera.
  • the image can be recorded either on the stationary or on the moving printed product.
  • the reading device transmits the recorded image to a downstream evaluation device.
  • the evaluation device determines the required information from the recorded image.
  • the reading device and the evaluation device can be combined in one device.
  • Digital cameras usually have software that offers various options for image processing or image analysis.
  • the definitions of the identification feature are transmitted to the evaluation device.
  • the transmitted definition serves the evaluation device as a basis for the image evaluation. This can affect the definition of the area of the printed image bearing the identification feature. It is thus possible for the evaluation device to ignore non-relevant image areas. This reduction in data reduces the time required for further image processing relating to the identification feature, and the performance of the device can be increased accordingly.
  • identification feature using a digital image of the printed image, which is independent of the physical printed product or the existence of a physical printed product is generated.
  • Image data originating from the prepress stage are particularly suitable. This determination is made in a particularly simple manner using suitable software. Based on the available image data, this identifies distinctive areas of the printed image and defines these as an identification feature. This determination made is preferably made available automatically for the evaluation of the print image captured by a camera. In this way, the time-consuming teach-in process by reading several sample prints, which is common today, can be dispensed with.
  • the identification feature recorded by the reading device is compared by the evaluation device with an identification feature stored in a data memory.
  • the evaluation device supplies at least one piece of information about the match between the recorded identification feature and the stored identification feature. It is irrelevant whether the stored identification feature is stored directly in the main memory of the device for print processing or in a higher-level database containing a large number of work orders.
  • the comparison increases the degree of automation of the device for print processing.
  • a controller of the device for further processing decides on the execution of subsequent processes such as a display to inform the operating personnel, machine stop, ejection of the relevant printed product, adjustment of the device for print further processing or execution of the processing of the printed product.
  • the identification feature detected by the reading device becomes one with the expected identification feature expected print product compared. This automatically checks whether the printed product supplied corresponds to the production order to be processed. If the result is positive, the processes required for scheduled further processing are initiated or the production flow is maintained. If the result is negative, the operator is informed accordingly and the printed product identified as incorrect is ejected from the scheduled production flow. Production errors due to incorrect printed products being fed in are thus reliably avoided.
  • a second embodiment provides for a comparison of the identification feature last recorded by the reading device with a previously recorded, in particular an immediately previously recorded, identification feature.
  • the evaluation device determines whether the last printed product recorded belongs to the production job currently being processed or to a new one. If there is no match, the process parameters required for the new production order are automatically read from a production database and corresponding adjustments are made to the device for further print processing. In this way, the manual effort involved in setting up and feeding in the printed products is significantly reduced. Of course, a combination of both comparisons is also possible.
  • the identification feature is preferably defined on the basis of a general rule applied to the respective printed image, such that the definition results from the printed image itself. Significant areas or properties of the printed image are found and defined as an identification feature.
  • the use of the general rule enables a high degree of automation, in particular since a constant rule is also used for the evaluation of the printed image detected by the reading device and this rule can be permanently stored in the evaluation device.
  • a further advantage can be seen in the fact that the identification feature can be scaled with the printed image.
  • the identification feature can thus be determined using a layout designed for a first format, for example DIN A4, while the print is actually in a different second format, for example DIN A5 and the Reading device thus detects a correspondingly reduced identification feature.
  • the detection range of the reading device preferably corresponds to a multiple of the extent of the identification feature to be detected.
  • a detection area that covers the entire printed image is particularly advantageous. In this way, there is no need to adjust the reading device, and positioning errors in the printed product to be detected do not impair the detection of the identification features.
  • the effort involved in determining the respective identification feature can be reduced if the uniqueness of the identification feature remains limited. Larger differences between the individual identification features are thus possible and the process reliability with regard to the identification is increased.
  • the uniqueness of the identification feature is limited to a specific period of time. This period can be, for example, a work shift or a work week.
  • the properties of the identification feature are then released for new identification features.
  • the uniqueness is restricted to an order list to be processed. As soon as an order list is marked as completely processed, the properties of the associated identification features are released.
  • the arrangement of the identification feature to be detected is defined relative to the device for print further processing.
  • the detection range of the reading device can thus be fixed in place.
  • the evaluation also takes place at a fixed location in relation to the device for further processing of the print and can thus be simplified.
  • the arrangement of the identification feature to be recorded is fixed relative to the contour of the respective printed product. This means that the detection of the identification feature is independent of the positioning of the printed product during detection.
  • perfect-bound brochures are produced, each consisting of a book block that is adhesively connected to a cover 1 .
  • Previously temporarily bound book blocks are individually placed in a row with the same orientation by means of a block feeder 33 to the in 2 shown perfect binder 31 fed to a perfect binder system.
  • a barcode 10' referring to an associated production order is printed on the upper side of each of these book blocks.
  • a camera 52 for reading 115 these job codes 10' is arranged in this block feeder 33.
  • An evaluation device downstream of this camera 52 for block detection compares the job code 10' read by the camera 52 with an expected job code 10. If this comparison 126 provides a match of the read actual code 10' with the expected target code 10, the read-in book block is transferred to a transport clamp 42 of the adhesive binder 31 for order-based processing. The book block is then guided past a number of processing stations 43 such as block spine processing stations and gluing units of a known type by the transport clamp 42 . Subsequently, the book block still held by the transport clamp 42 is joined in a joining station to a cover 1 that has been provided by means of joining 206 by means of an adhesive. The spine area of the brochure is pressed onto this hanging 206 and guided out of the adhesive binder 31 for final processing.
  • the book block in question is instead withdrawn from immediate further processing by the adhesive binder 31 by means of a product diverter 34 upstream of the clamp transport 41 of the adhesive binder 31 by ejection 204 .
  • a plurality of envelopes 1 to be processed are magazined 201 and fed to the envelope magazine 37 of the adhesive binder 31 as a stack.
  • An envelope 1 located at the end in this magazine 37 is transferred from the store to a transport device after it has been separated 202 .
  • This transport device feeds the individual envelope 1 to the said joining station.
  • this transport device comprises slides 46 which, in pairs, grip a single envelope 1 at its trailing edge in a conveying manner and transport it along guides 45 aligning the envelopes.
  • the device for the cover transport includes a further camera 53.
  • This further camera 53 is used to record 121 the printed image 2 of the individually transported envelope 1.
  • the read printed image 2 contains the in 1 illustrated areas 12.1, 12.2, 12.3, which together form the identification feature 11 '. All areas 12.1, 12.2, 12.3 of the identification feature 11' are within the spatial Detection area 54 of the camera 53.
  • the camera 53 makes the captured image available to an image evaluation device 63. Because of the performance of modern cameras, this image evaluation device 63 is integrated in the camera 53 .
  • the image evaluation device 63 reads the relevant image areas 12.1, 12.2, 12.3 from 120 and compares the actual identification feature 11' captured by the camera 53 with an expected target identification feature 11 and transmits the result of this comparison 127 to a controller 61 of the adhesive binder system 31 If the determined actual identification feature 11′ matches the expected target identification feature 11, the envelope 1 is fed through the envelope feeder 36 to further processing stations of a known type for preparatory work 205 such as creasing. After the joining 206, post-processing 207 already takes place in the adhesive binder 31 by pressing the spine area of the printed product.
  • the affected envelope 1 is withdrawn from the product flow by an envelope diverter 38 of the envelope feeder 36 and placed in an envelope delivery 39 . There it is removed by the operating personnel.
  • the ejecting 204 of the cover 1 when the book block is identified as "wrong” and the ejecting 204 of the book block when the cover 1 is identified as "wrong" are not shown.
  • the expected target identification feature 11 of the cover 1 is stored in an order data record 22 and represents the order code 23.

  • the identification feature 11 of the envelope 1 is derived from the design 100 of its printed image 2 112. This is done using an in the right part of the 1 shown digital representation 8 of the print image 2 from properties of the represented print image.
