  • Other versions are feasible.
  • the print head Similar to an office printer, a new artwork or picture element or printed image is played.
  • the printhead needs so-called RIP files, the essentially determine in which sequence and with which drop size each individual pressure nozzle in each of the possible printing inks is controlled. Due to the print resolution, the number of colors and the variable droplet size, the amount of data is considerable.
  • a "just-in-time" supply with new production data would increase the bandwidth of the communication interfaces to the printheads, for example a 720 dpi print engine, with a machine capacity of 48,000 containers per hour and common with print on five colors (CMYK and white) on a surface of 70 x 140 mm 2.
  • the store represents a dot with one byte
  • a press that is expected to be available on the market is expected to have 8 hours of permanent machine performance, better is a 24/7 operation. If two areas per container with a width of 70 mm and a height of 140 mm are printed, then with a production capacity of
  • the front page of the product can always be the same and the back of the product with the legal texts can be country-specific. It can be a "four-color filler” downstream and it can be printed four different "labels” depending on the flavor (banana, vanilla, strawberry, chocolate). You can always say something about a Georgia league edition the same labels are printed and only the player images are changed. Similar to a "letter soup”, “messages” or contiguous images can be created across several containers, chess pieces, dominoes (dots, pictures). All these examples have in common that they hold a certain amount of different artworks or picture elements or print images or parts of it and thus a variety is generated.
  • the sequence can be centrally controlled. It may be that in further process steps until the delivery of the product errors occur and one or more articles must be (re) produced again.
  • the most important subsequent process steps can be mentioned, the curing of the ink, control of the imprint (an actual faulty print was produced) or the filling (a filling error, closing error), packing (packing error).
  • certain variants can be "lost" and require targeted post-production of those in the batch.
  • the printed sheet as a whole is constant.
  • Another well-known way is, and this is used, for example, when printing instruction leaflets in black on white paper to check against a PDF file as a template. This is where the man-made and possibly erroneous step of creating a wrong master print and turning it off for printing is turned off.
  • the aim is to exchange the (Golden) Master Print template for a PDF template.
  • the PDF template is synonymous with all templates that have been calculated by machine, rather than through the control system read back, for example, by a camera image. In the prior art so-called PDF files are exchanged between two print batches.
  • Master Print both the template, generated by the scanning of the reference printed image or reference picture element as well as the PDF file or other file templates summarized.
  • the master print may require twice as much resolution in both directions compared to the print data. That means instead of 600 MB / s or 1.2 GB / s, a communication traffic of 2.4 GB / s or 4.8 GB / s would be incurred.
  • the number of sequences can be centrally controlled. This is needed to produce a commissioned set of sequences. For example, an order is placed, 2000 times a Christmas calendar, consisting of 24 containers, to produce with 24 different motives.
  • the 24 motifs are related. In the simplest case, the numbers 1 to 24 are plotted. In the prior art, it is customary to print the sequence of the 24 motifs until 2000 sets are available at the last process step, the packaging of the Christmas calendar, or it can be safely achieved.
  • the number of sequences in this example is 2000. In practice, about 5% more is produced, if one calculates with about 5% production errors.
  • the 5% exemplified are the sum of all possible errors in all production process steps. That Instead of the commissioned 2000 sequences, an overproduction of 2100 sequences is produced in the factory right from the start in order to get successions at the end of 2000. Only complete sets of Christmas calendars can be delivered. If an error occurs in a container at a process step, then the complete sequence would have to be diverted and later reorganized with overproduction.
  • the disadvantage is that the master print is exchanged between two print batches. If the master print is exchanged in-time, a permanent, expensive data stream is necessary. Costly, because a very high amount of data per second is required and the infrastructure must be extremely available.
  • the disadvantage is that it is simultaneously checked against more than one master print. Thus, e.g. In the following example it can not be distinguished whether the print is right or wrong: It is to be produced both a container with imprint "color" for the American area, as well as for the English area, here "color".
  • the control system loads both (partial) artworks or picture elements or print images. It is always in the one template a "okay” and in the other template a “not okay” generate. What remains unanswered is the question of which version would have been produced in the controlled container. Another example is the list of ingredients on the back of the container.
  • the front could be printed with the "vanilla” artwork / print image / picture element, the back with the list of ingredients of the chocolate.

L'invention concerne un dispositif de contrôle (50, 52) servant à contrôler une pluralité de récipients (10) sur lesquels au moins un premier élément d'image (B1-B8) a été imprimé par une machine d'impression directe (20), et comportant un dispositif de transport (40) qui achemine les récipients (10) à contrôler munis d'une impression sur un trajet de transport, de préférence individuellement et les uns après les autres, vers le dispositif de contrôle (50, 52) et/ou les en évacue. Le dispositif de contrôle (50, 52) contrôle les récipients (10) munis d'une impression au moins quant au premier élément d'image (B1-B8) appliqué par la machine d'impression directe (20), et présente un dispositif de mémoire (53) dans lequel est stocké au moins un ensemble de premiers éléments d'image (B1-B8) à contrôler. Selon l'invention, le dispositif de contrôle (50, 52) effectue le contrôle en prenant en compte pour chaque récipient (10) à contrôler au moins un élément d'image (B1-B8) de l'ensemble de premiers éléments d'image (B1-B8) à contrôler associé sans équivoque audit récipient (10) à contrôler.
