Description

Unterschrift, sondern auch ein neuer Sicherheitsdruck aufgebracht wird.Signature, but also a new security print is applied.

Als besonders vorteilhaft hat sich die Verwendung eines Farbstoffs auf Kugelschreiberpastenbasis für den Sicherheitsaufdruck herausgestellt, sofern die Faste derjenigen in dem für die Unterschriftsleistung verwendeten Kugelschreiber entspricht und sie in ihrer Konsistenz auf die Anforderungen des Druckverfahrens abgestimmt ist Die Paste zur Herstellung des Sicherheitsaufdrucks wird nämlich mit einem Netzmittel für die Herabsetzung der Oberflächenspannung und mit einem Lösungsmittel für die Verlängerung der Trocknungszeit versetzt Auf diese einfache Weise läßt sich sicherstellen, daß die den Kugelschreiberpasten eigene und in Kugelschreibern auch notwendige Kohäsion nicht dazu führt, daß die Farbe auf den Druckwalzen zusammenläuft und eine zu ungleichmäßige Einfärbung des Klischees erfolgt Zum anderen wird die Trocknungszeit der Faste, die bei Kugelschreibern so klein wie möglich gehalten wird, für die Verwendung in Druckmaschinen verlängert;The use of a dye based on ballpoint pen paste has proven to be particularly advantageous the security imprint exposed, provided the fast corresponds to the one in the ballpoint pen used for the signature service and it in their Consistency is matched to the requirements of the printing process. The paste used to produce the Security imprint is namely with a wetting agent to reduce the surface tension and mixed with a solvent for the extension of the drying time This way you can ensure that the pen pastes own and in ballpoint pens as well necessary cohesion does not lead to the fact that the color on the printing rollers converges and one that is too uneven Coloring of the cliché takes place on the other hand, the drying time of the fast, which occurs at Ballpoint pen is kept as small as possible, elongated for use in printing machines;

ίο die Farbe könnte sonst bereits vor der Abgabe von den Walzen einen zu hohen Trocknungsgrad erreichen. ίο the color could otherwise already before the delivery of the rollers are too dry.

Forgery-proof ID card, especially under a layer that can be written on Their credit card made of plastic, with an S Protection against forgery should be given by the fact that Security imprint exhibiting signature when trying to apply the one applied to this layer field, characterized in that the signature is to be erased, and the layer at the same time removed with the use of solvents and the security bar underneath Sicherheitaufdrack becomes visible with the same color print. As the layer for inclusion material is applied, with which the underside of the signature is made of a thin opaque written performance is made of thermoplastic film, which is

The entire layer of rens coordinated ballpoint pen paste is used, but the one with the signature can easily be removed and corresponds to the paste in the ballpoint pen used for the signature service with simple means with a new replaceable ballpoint pen (e.g. you can use heat-sealing foils on the market)
