Sorting and packaging solution for high security documents

Higher and even higher security standards are being applied to official documents, contracts, vehicle registrations and other high-level security documents. With our modular DISS all processing steps from the quality control, to the sorting, grouping and packaging of sensitive documents, can now be conducted automatically.

Short description

Reliable processing of high security documents

Watermarks, UV printing, infrared printing, holograms or security numbering are only some of the security signs which are becoming more and more innovative in order to protect sensitive documents like birth certificates, licenses, visas or financial documents against forgery and abuse. Hence, during the production, subsequent treatment or personalization of such documents, a steady monitoring of these security features is essential to guarantee their genuineness. With the DISS we have developed a modular system which checks security elements reliably and which as well can recognize and reject damaged or incorrect documents. Afterwards these documents can be sorted or be selectively stored temporarily in groups. Moreover holograms or labels can be applied with various additional modules, or automatic packing lists can be made up for accumulated document groups. Also different modules are available for packaging and mailing preparation. With its high degree of the automation in all processing steps, the DISS is the ideal solution for the processing of high security documents.


For high security documents such as:

  • Birth certificates
  • Vehicle registrations and licenses
  • Visas
  • Financial documents
  • Contracts
  • etc.

Sorted, grouped or enveloped high security documents

Document feeding

Documents are fed further processing in on-line or off-line mode. In a comprehensive quality control, front and back sides are compared with the database. Various security features are checked for their presence and correctness. Among other things, RFID chips, UV verification and infrared verification, OCR and bar code verification as well as optical signs like logos or coats of arms, are checked.

  • Single-sheet printer for delivery notes
  • Database-supported on-demand printing
  • Buffer for constantly timed supply
  • Multiple batch supply
  • Processing pre-printed covering letters / documents
  • Single sheet feeder
  • Friction feeder
  • Check and comparison of given parameters (e.g., size, intactness)
  • Selective checks thanks to database linking
  • Check of front and back sides
  • UV verification
  • Infrared verification
  • OCR and bar code verification
  • Recognition of logos, seals and other optical elements
  • Check of applied RFID chips

Document processing

After thorough checking of the documents, different subsequent treatment functions may be chosen. For example, selective paper piles can be formed, numerical groupings can be made, or special groupings based on information provided from a database. Optionally, transport labels, or information labels, which were pre-printed or personalized, can be applied.

  • High-capacity printers produce individualized covering letters in color or monochrome
  • Database-supported on-demand printing
  • Buffer for constantly timed supply
  • Application of pre-printed labels
  • Application of security labels (e.g., scratch-off, seals, holograms, kinegrams, activation stickers)
  • Printing and applying of transport labels
  • Printing and adding of delivery notes and other accompanying documents


The inserter processes documents in the format DIN-A6 to DIN-A5 (or DIN-A4 pre-folded) and inserts them in envelope formats C6 to C5. Special formats are possible on request. During the inserting procedure, enclosures can be fed from different enclosure stations, either continuously or selectively. In the standard module, up to 4 enclosure stations can be integrated. Other stations are possible on inquiry. The system can be equipped with as many supplement stations as may be required. All accumulated products of a mailing are fed into an envelope and afterwards securely closed.

  • Separation of the envelope via vacuum sucker from below
  • Feed capacity of the enveloping station amounts to approx. 250 mm (optionally extendable with High Capacity Feeder for up to 2,000 envelopes)
  • Infinitely variable for different envelope formats (by quick fasteners, fixed stops and millimeter scales, individual formats on inquiry)
  • Sensors check the orderly opening of the envelope flap after its selection
  • Processing of all automation-compatible envelopes (possible on request: special envelopes, e.g., made of plastic, with open address windows, without address windows, etc.)
  • Inserting the collected products (card carrier, documents, enclosures, etc.) occurs using insertion finger in envelopes opened by vacuum grip arms
  • Envelope thickness up to 12 mm (also more on request)
  • Product recognition avoids filling wrong envelopes by operators (e.g., via linear bar code and QR code scanner, datamatrix scanner, OCR reading, or logo recognition)
  • Matching of mailing/shipment arrangement and envelope
  • Sealing of the envelope by flap moistening or via glue
  • Optional letter flip over module for the filing / issueing of envelopes with the address “face-up” or “face-down” (text on top or below)
  • Weight examination of the final mailing
  • Discard tray for mailings with weight divergences for manual examination regarding completeness
  • Identification of sealed envelopes for the comparison of the read information in the address field via bar code or QR code scanner, datamatrix scanner or OCR reading
  • Cameras for the recognition of logos and other visual images
  • Reading of contactless RFID chips in the sealed envelopes via aerial (also possible: “locking” of the chip for protection against unauthorised reading during transit)
  • Readings from above or below possible
  • Transport notes, sender’s address, courier data, advertising messages and other personalized data can be printed on the closed envelope (e.g., via inkjet printer)
  • Optional application of labels after enveloping (e.g., security label to seal the envelope flap, address label with courier or stamping information)
  • Preprinted or individually printed labels
  • Optional integration of standard postage franking machines for prepaid postage charges (by embossing or inkjet printer)
  • Application of personalized forms (e.g., retour forms / receipt acknowledgement etc.) on the closed envelope
  • Pre-personalized or printed forms
  • Comparison of form and envelope by integrated reading before bringing them together


The documents and document groups, which have been checked and processed further, can be optionally banded and packaged in the final production step. Different options of packing are available, e.g. cartons, boxes, postal packs, or envelopes of many kinds. As an option, further quality checks can be introduced at this point, for instance a weighing scales, to check the final mailing. The attachment of mailing documents or retour forms on the envelopes is also an optional possibility.

  • Packaging of the envelope for the collective dispatch after previous grouping possible
  • Banding of an envelope pile with a banderole made from paper or plastic
  • Crossbandingfor particularly manipulation- resistant collections
  • Postal boxing system for the fully automatic filling in storage boxes

Special features

  • Comprehensive quality control
  • Selective grouping thanks to database support
  • Selective personalization by labels / Ink-Jet
