Definitions

  • the invention relates to a method for the rapid generation of a security imprint, in the manner specified in the preamble of claim 1 and an associated arrangement for carrying out the method.
  • the method comprises steps for providing variable data immediately before printing, in particular for forming marking data and for composing constant and variable data for time-optimal printing control of the franking machine for a column-wise printing of a franking machine print image.
  • the method enables, among other things, a quick change of the plate text part by means of editable data stored in the franking machine without interrupting printing.
  • the invention relates to franking machines that provide a fully electronic impression for franking mail, including an advertising slogan and a mark.
  • the franking machine is equipped with at least one input means, an output means, an input / output control module, a memory for at least one advertising cliché, a control device and a printer module.
  • a franking machine generally creates an imprint in a form agreed with the post right-aligned, parallel to the upper edge of the mail item, beginning with the content of the postage value in the postmark, the date in the day stamp and stamp imprints for advertising slogans and, if applicable, the type of shipment in the election print stamp.
  • the post value, the date and the type of shipment form the variable information to be entered according to the piece of mail.
  • the postage value is the transportation fee paid in advance by the sender, which is taken from a refillable credit register and used to clear the mail item.
  • the date is a current date or a future date in a postmark. While the current date is automatically provided by a clock / date module, the desired future date must be set in the case of manual pre-dating. Pre-dating is interesting in all cases where the volume of mail is processed and franked very early, but has to be dispatched on a certain date.
  • the variable data for the date can be embedded in the day stamp as well as when the postal value is printed.
  • the approved advertising clichés can contain a wide variety of messages, in particular the address, the company logo, the mailbox and / or any other message.
  • the advertising cliché is additional information in the postal sense that must be agreed with the postal authority.
  • a franking machine message printing system is already known from DE 37 12 100, the characters to be printed comprising a postage value and a remotely transmitted message.
  • the electrical postage meter is equipped with a postage meter accounting circuit, which provides the postage value, equipped with a telephone or transmission connection, with a message input device, with a transmission control system, with a printer and with a memory.
  • the memory delivers the message, so the characters to be printed are printed at least in part on the basis of data stored in the memory.
  • the advertising slogan can be selectively changed by the data center when a request is sent to the data center via the transmission port with the message input device, the verification of the coded request in the data center was positive, and the message transmitted by the data center has been checked in the franking machine. It has also already been proposed to allow a third party to advertise in their own mail by letting the space for the franking machine message. A third party message is then transmitted to the data center. The data center must feed the third party's message to the franking machine and also controls the use of the message in the franking machine. However, measures are always required to ensure that the connection is maintained, that the message is authorized and that the data is correct.
  • the pixel data for the advertising message must be transmitted from a central station in a completely new way, the number of prints being monitored, or the advertising message to be printed is manually entered into a memory using a keyboard, to print the postage, date and text lines one after the other.
  • the disadvantage here is that when manual input information is changed, the previous old input information is lost. Only advertising messages stored in the head office can then be accessed. Another disadvantage is that the change cannot be made without interruption.
  • the overprint is electronically and mechanically complex. The use of printing drums on the one hand or dot-matrix printers on the other hand also leads to undesirable noise pollution.
  • An automatic transmission system with user (chip) cards is known from EP 294 397.
  • the user cards are equipped with a microprocessor and a data output unit.
  • the franking machine has a terminal for the user cards with a value processing section, programming means for a card microprocessor and a processing section microprocessor for executing a programmed handling procedure, a graphic being loaded from the card memory through the terminal into the printer memory.
  • the graphics can only be changed as a whole, ie by reloading an externally modified one Postage stamp including postmark using user cards.
  • Security cannot be increased here by new advertising clichés. Such can be easily generated electronically.
  • a changed advertising cliché would indicate manipulation.
  • the postal authority has not yet provided for such an evaluation.
  • DE 38 23 719 discloses a security system for use with a character printing authorization device.
  • a computer of the franking machine is assigned a memory for the data to be loaded, the graphic change and the data of the associated date.
  • the computer of the franking machine accesses an external dialing device via a connection device (modem) which selects a character pattern to be printed.
  • modem connection device
  • the printed character pattern will be used to check the security of the authorization of the franking machine.
  • the entire printed image having that special character pattern is to be evaluated by the postal authority, which is only possible with great effort.
  • Such a bar code by means of a separate printer is known from US Pat. No. 4,660,221 and US Pat. No. 4,829,568, the latter US patent also printing a character with offset elements, the offset of which contains the relevant security information.
  • the evaluation is carried out, for example, in US Pat. No. 4,641,346 by reading such a character column by column and comparing it with stored characters column by column in order to recover the security information.
  • the evaluation is accordingly complicated and can only be carried out by the postal authority using complex equipment.
  • Another security system uses imprints in the form of a diagram (US Pat. No. 5,075,862) within the Franking machine stamp imprint. If printing elements have failed, the dots are missing in the printed image, which can signal an alleged forgery. Such markings in diagram form within the franking machine stamp imprint are therefore not so secure. Mechanical evaluation is difficult even with an error-free print, since the entire printed image must always be evaluated.
  • DE 40 03 006 A1 has proposed a method for identifying mail to enable franking machines to be identified, a multi-digit crypto number including the date, the machine parameters, the post value and the advertising slogan being formed and cached separately.
  • the crypto number is additionally inserted into the print pattern during printing via a printer control which sets the printer means.
  • a counterfeit or any imitation of the franking machine stamp can be identified by means of the crypto number by means of a postage imprint that has not been billed.
  • Even with a large number of users of a single franking machine the user who manipulated the postage value can easily be found out. However, this is not a fully electronically generated print image for an impact-less printer.
  • DE 40 34 292 has proposed for a fully electronically generated print image to store only a constant part of the franking image in the franking machine and to send the other associated variable part from the data center of the franking machine in order to assemble the final printed image.
  • the fully electronically generated advertising cliché is just as much a part of the constant data of the franking image as the frame arrangement of the value and day stamp with location and, if applicable, the postcode.
  • the advertising cliché cannot be partially modified in that franking machine.
  • the cliché should be changed via the actuating elements in the new franking machine, without this requiring prior approval from a data center or through the post office, and without this affecting the security of the billing and without such franking Postgut is sorted out as a forgery at the post office. At the same time, the security against counterfeiting should also be increased.
  • variable data of the marking in one or more windows within a fixed by the postage meter printing image in the case of a fully electronically generated printing image given frame when printing.
  • at least one combination number of predetermined sizes is formed after the completion of all inputs and this is encrypted according to an encryption algorithm to a crypto number, which is then converted into a marking.
  • at least one number assigned to the higher digits of the combination number is a monotonically variable quantity.
  • This marking is preferably printed in the form of a bar code and / or as a series of symbols in a field of the franking machine image simultaneously with this by the single printer module.
  • the symbolism in addition to the mechanical one also enables a visual evaluation by a trained examiner who evaluates the form and the conceptual content of the symbols in the post office.
  • the shape of the symbols, with orthogonal edges, enables particularly easy and quick machine readability through an integral measurement of the degree of blackening.
  • the row of symbols achieves a higher density of information and thus saves space in the franking machine print image, or more information can be printed coded using the graphic symbols.
  • a print control signal is generated after a print request by the Marking data converted into binary pixel data during column-by-column printing in the course of a special printing routine are inserted column-by-column in the currently printed column at a predetermined position.
  • the invention is based on the fact that, after switching on, the postage value in the value print corresponding to the last entry before switching off the franking machine and the date in the day stamp corresponding to the current date are automatically specified that the variable data in the fixed data for the frame for the print and be electronically embedded for all associated data that remain unchanged.
  • These variable data of the window contents are hereinafter referred to briefly as window data and all fixed data for the value stamp, the day stamp and the advertising slogan stamp as framework data.
  • the frame data can be taken from a first memory area of a non-volatile working memory.
  • the window data can be taken from a second memory area for the purpose of combining them into an overall representation of a franking image.
  • the data from the two memory areas are combined in accordance with a freely selectable assignment before printing to form a pixel print image and are completed during printing to form a column of the entire franking machine print image.
  • Those variable data which are embedded in the printing column during printing comprise at least the marking data. The time required for the previous assembly of the entire pixel image with the rest of the data, is reduced accordingly.
  • the previous composition is similar to the date in the postmark and as with the postage in the value print, whereby the variable information can be added and modified subsequently in the window provided. It is assumed that a variable part of the text can be embedded in a frame for an advertising cliché in the same way as for the other window data and that a window is defined within the overall presentation of the advertising cliché. In order to save time, only those parts of a graphical representation that are actually changed are saved when a change is made.
  • the method assumes that loading of agreed plate types via MODEM or chip card and selection of a plate type can be carried out in a manner known per se.
  • optional editing of a cliché text part stored in the franking machine and assembly and display of an overall representation and, if appropriate, storage of the edited text part before printing is additionally guaranteed.
  • the arrangement for changing the cliché text part for franking machines has, in one variant, a pixel memory and a non-volatile working memory with separate memory areas.
  • the second storage area is provided for window data, inter alia for a number of assignable cliché text parts.
  • the non-volatile memory is available with a device that stores the data in this second Memory area can change automatically in a predetermined manner in connection.
  • a message is to be transmitted in an agreed window of a field for an advertising cliché in the franking imprint, the message directly addressing the addressee in plain text.
  • the message can be an alphanumeric text part that has not been agreed with the post office and contains any information, e.g. Contains references to company holidays, trade fairs, conferences and / or public events.
  • the invention is therefore further based on the consideration of agreeing an approval process for cliché types that can be supplemented in part by the customer, in order to enable the function in the franking machine to change alphanumeric text parts within the cliché in the franking machine.
  • This eliminates the need to request new advertising clichés from the franking machine manufacturer or dealer or its data center each time, and the associated complex security procedure, including the transmission of coded signals for cliché data using a modem, is also eliminated.
  • a change in the text may not lead to reduced security against counterfeiting and, on the other hand, when checking the franking of postal items which are provided with such a change in the cliché text part, it should not automatically cause the postal items to be rejected as allegedly counterfeited.
  • a corresponding marking is therefore generated for a security imprint, taking into account the fixed franking machine pixel image data, which remain unchanged when the cliché text is edited.
  • the invention it is proposed to transfer hexadecimal frame data, window data and assignment data into the respective separate memory areas of an additional non-volatile working memory and to store them there in order to display the printed image before printing and to be able to edit the cliché text parts. It is then transferred to the volatile pixel memory and the window data is classified according to the assignment data in the frame data.
  • All alphanumeric characters or symbols are stored in pixel memory 9 as binary data.
  • Data for alphanumeric characters or symbols are in the non-volatile working memory 5 compressed in the form of a hexadecimal number.
  • the compressed data are read from the working memory 5 and converted with the aid of the character memory 9 into a printed image having binary pixel data, which in such a decompressed form is volatile Memory 7 is saved.
  • Working memories 7a, 7b and pixel memory 7c are used below to explain the invention, although this is physically preferably a single memory chip.
  • the working memory 7b and the pixel memory 7c are connected to the printer module 1 via a printer controller 14 having a print register (DR) 15 and an output logic.
  • the pixel memory 7c is connected on the output side to a first input of the printer controller 14, at whose further control inputs there are output signals from the microprocessor control device 6.
  • the arrangement for the rapid generation of a security imprint for franking machines has, in the non-volatile working memory 5, a first memory area A (for the data of the constant parts of the franking image, among other things, the advertising slogan frame, an associated indication i identifying the respective frame), and a pixel memory area I in volatile pixel memory 7c.
  • a stored block of cliché text is further identified by an assigned name or indication j.
  • the data for a first assignment of the names of the cliché text parts to the names of the cliché frames are available in a third memory area C of the non-volatile working memory 5. This assignment enables the data records in memory areas A and B to be addressed and called up automatically.
  • the memory areas A to T in the non-volatile working memory 5 can contain a large number of sub-memory areas, under which the respective data are stored in data records.
  • the strings of numbers (sTrings) that are entered for the generation of the input data with a keyboard 2 or via an electronic balance - not shown in FIG. 1 - connected to the input / output device 4 and calculating the postal value are automatically stored in the memory area T of the non-volatile memory 5 stored. This ensures that the last input values are retained even when the franking machine is switched off, so that after switching on the postage value in the value print is automatically specified in accordance with the last entry before the franking machine was switched off and the date in the day stamp in accordance with the current date.
  • data records of the sub memory areas for example A i , B j , C etc., are also retained. In each data record of a sub memory area A i , B j or B k , control code and run length-coded frame or window data are alternately contained one after the other.
