Derived from banknote technology, this highly secure, custom anti-fraud stamp allows you to provide a high level of protection for your most sensitive official documents. Authentication is performed instantly using a UV lamp that reveals invisible ink on all your non-optically brightened papers. Fully customizable, this anti-fraud security stamp ensures your official documents are effectively protected.
By using the anti-fraud security stamp, you provide your official documents, certificates, and diplomas with a strong guarantee against forgery. Once your documents are signed, you stamp your unique personalized logo in invisible ink on top, making any attempt at reproduction impossible. Authentication becomes immediate thanks to our UV magnifier lamp or our mini UV lamp, which react with the chemical components of our UV stamp ink to make it visible to the naked eye. For maximum protection and optimal use, it is recommended to use non-optically brightened papers, which better reflect invisible UV ink. Indeed, papers without optical brighteners do not absorb UV rays, allowing better ink visibility. However, it is possible to use the stamp on regular paper by using a special yellow ink that turns white when exposed to a UV lamp. Check out our range of security papers available in stock.
To learn more about the uses of security paper, see the following two articles: What is security paper for? and How many fake documents circulate in (and out of) your company?
The custom stamp is similar to any other stamp. Measuring 11.5 cm x 7 cm and weighing 350 grams, it remains a discreet solution for securing your documents. The ink cartridge’s lifespan is outstanding and can secure up to 15,000 documents. In addition, a unique and customizable serial number, visible under UV light only on non-optically brightened paper, can also be added. In case of loss or theft of the stamp, we will create a new professional stamp with a new serial number, rendering the old one obsolete. Thus, if a stolen stamp is used by someone else, checking the serial code will reveal the forgery.
Below, you will find a video of the security stamp detailing the usefulness of a security stamp in a company. You will also see the procedure for changing the ink cartridge of your security stamp.
1: Choose the imprint format
Whether small, rectangular, or circular, the stamp imprint is customizable from the following formats:
Select the number of colors you wish to appear on your company stamp, up to 4 colors. Each color comes in 3 types:
Standard visible ink: similar to standard professional stamp inks, this ink remains visible under a UV magnifier lamp and in daylight.
Chromo-tropic: Ink with chemically linked polymer chains that show one color in daylight (red, yellow, or blue) and a different color under UV light. Exposure to UV from a UV flashlight reorganizes the chain structure, changing the initial colors into new ones: fluorescent green, blue, yellow, or red. Note: to use a stamp with chromo-tropic ink, you must have non-optically brightened paper that does not react to UV rays and enhances UV ink visibility.
Invisible ink: Completely invisible in daylight, exposure to concentrated UV rays photo-initiates the polymers and monomers in the ink, destabilizing their chains. This excitation makes them visible, revealing a yellow or red color. 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 area. Leave at least 0.7 mm between each area.
