High Security Authentication stamp

Derived from the technology applied to banknotes, this highly secured stamp allows you to give a high level of security to your most sensitive official documents. Authentication is carried out instantly with a UV lamp revealing the invisible ink. Fully customizable, this security stamp enables you to efficiently secure your official documents.

The right reflex: systematically stamp your sensitive documents for an optimal security process.

With the help of this security stamp, you ensure strong protection against tampering to your official documents, certificates. Once your documents are signed, you stamp your unique customized logo with invisible ink on it making any attempt at duplication impossible. Authentication is immediate thanks to the UV lamp making the chemical components of the ink react and become visible to the naked eye. For maximum protection, it is recommended to use papers without optical brighteners, for better reflection of the invisible ink under UV. Look up our secure paper range in stock in our store.

To find out more about the uses of security paper, see the following two articles: What is secure paper used for? and How many fake documents are circulating in (and out of) your company?

The security stamp is similar to any other stamp. With dimensions (11.5cmx7cm) and a total weight of 350 grams, it is a discreet solution for the security of your documents. The ink cartridge has a remarkable shelf life and can secure up to 15000 documents. In addition, a unique and customizable serial number , visible under UV rays, can also be placed. In case of loss, or theft of a stamp, we recreate a new stamp with a new serial number, making the old number obsolete. Thus, if a stolen stamp is used by another person, verification of the serial code will make the forgery visible.

Below, you will find a video explaining in details the secure stamp and its usefulness in a business. You will also find the handling to change the ink casette of your secure stamp.

Customization of your secured stamp

1: Select the print format

Whether it is small, rectangular or circular, the print of the secured stamp can be customized in the following sizes:

2: Select your security color sets

Select the number of colors, up to four colors, that should appear on your stamp. Each color is available in 3 sizes:

- Visible black : similar to conventional ink stamps, this ink will remain visible under UV and under daylight.
- Chromotropic : Ink possessing chemical polymer chains linked together that give a particular color in daylight: red, yellow or blue and under UV light another color. The UV light contributes by reorganizing the structure of the chains, transforming the initial colors into new colors: green, blue, yellow or fluorescent red. This ink isn't working on standard paper, it requires paper without optical brightener.
- Invisible ink : Completely invisible in daylight, the concentrated UV rays contribute by photoinitiating the chemical polymers and monomers present in the composition of the ink, making their chains unstable. This excitation makes them visible and a yellow or red color then appears.
