What is security print?
Security print uses a variety of techniques to prevent fraud and forgery of valuable documents such as cheques, certificates, ID cards, events tickets and vouchers.
At Hague, we use a variety of overt and covert methods to ensure the security of printed documents. These include:
Overt security print solutions
The presence of several overt security methods act as deterrents to anyone considering attempting to copy a document.
Adding a personalised hologram to a document makes it incredibly difficult to copy as holograms cannot be replicated – even those with specialist equipment would struggle to copy a custom hologram. Holograms are made more secure with the addition of tagganted foil (see covert solutions below).
Watermarks are added to paper when it’s made, so cannot be photocopied or easily replicated.
Adding numbering to documents aids verification, however a simple sequence of numbers can be easily guessed. To combat this we use complex number matrices that would be virtually impossible to decipher.
Covert security print solutions
Normally used in addition to overt methods, covert security print solutions make it incredibly difficult to replicate documents. Attempting to copy a document with covert security print features would require a highly sophisticated set of specialist tools just to work out which methods were in use.
Covert security paper
Unlike watermarked paper covert security paper has identifying features that cannot be seen by looking at the paper. The paper is marked with UV ink or ink which changes when the paper changes state.
Using the latest genetic technology, we can encode DNA into inks for printing. This is a completely covert security print method, and sophisticated techniques are required to verify the ink as genuine. The DNA is also encoded, making it hard for anyone to decipher and replicate, even if they worked out security inks were in use.
A taggant is a pigment or dye that’s included within a hologram which isn’t visible to the human eye. The taggants emit wavelengths of light that can only be detected by a special reader. Using a hand-held reader it’s easy to quickly identify if a hologram is authentic.
