Derived from technologies applied to banknotes, this secure anti-fraud stamp, with highly secure personalized ink, provides a high level of security for your most sensitive official documents. Authentication is done instantly using a UV lamp, revealing the invisible ink on all your non-optically brightened papers. Fully customizable, this secure anti-fraud stamp allows you to effectively guarantee your official documents.
Thanks to this secure anti-fraud stamp, you provide your official documents, certificates, diplomas, with a strong guarantee against forgery. Once your documents are signed, you stamp your unique personalized logo with invisible ink over them, making any attempt at reproduction impossible. Authentication becomes immediate with our UV magnifying lamp or our mini UV lamp, which activates the chemical components in the ink of our UV stamp, making it visible to the naked eye. For maximum protection and optimal use, it is recommended to use non-optically brightened paper, as it better reflects the invisible ink under UV light. Indeed, non-brightened paper does not absorb UV radiation, allowing for better ink visibility. However, it is still possible to use the stamp on ordinary paper by using a special yellow ink that turns white under UV light. Check out our range of secured papers available in our store.
To learn more about the uses of secured papers, read the following two articles: What is secured paper used for? and How many fake documents circulate in and out of your company?
The personalized ink stamp is similar to any other stamp. With dimensions of (11.5cm x 7cm) and a total weight of 350 grams, it remains a discreet solution for securing your documents. The ink cartridge has an exemplary lifespan and allows for the security of up to 15,000 documents. Moreover, a unique and customizable serial number, visible only under UV rays on non-brightened paper, can also be added. In case of loss or theft of the stamp, we can create a new professional stamp with a new serial number, rendering the old one obsolete. Therefore, if a stolen stamp is used by someone else, verification of the serial code will reveal the forgery.
Below, you will find a video of the secure stamp explaining in detail the usefulness of a secure stamp in a company. You will also find instructions on how to change the ink cassette of your secure stamp.
1: Choose the imprint format
Whether it is small, rectangular, or circular in shape, the stamp imprint is customizable among the following formats:
Select the number of colors you want to appear on your company stamp, up to 4 colors. Each color is available in 3 formats:
Classic visible ink: similar to classic professional stamp inks, this ink remains visible under UV light or illuminating magnifying glass and in daylight.
Chromo-tropic: Ink with chemically linked polymer chains that gives a specific color in daylight (red, yellow, or blue) and a different color under UV light. UV exposure with a UV flashlight reorganizes the structure of the chains, transforming the initial colors into new colors: fluorescent green, blue, yellow, or red. Note that to use a stamp with chromo-tropic ink, it is necessary to have non-optically brightened paper, which does not react to UV rays and highlights the UV ink.
Invisible ink: Completely invisible in daylight, the exposure to concentrated UV rays photo-initiates the polymers and monomers present in the ink composition, destabilizing their chains. This excitation makes them visible, and a yellow or red color appears. Invisible UV ink works on all papers but is much more visible on non-optically brightened paper.
Precision: You can only use one ink per zone, and there must be a minimum distance of 0.7mm between each zone.
