Security Printing - What is security printing?
Definition of SECURITY PRINTING:
The use of a variety of special face materials, printing techniques, and printing materials to improve the security of an item by preventing forgery, counterfeiting, and tampering. These techniques are commonly used in the production and printing of security labels.
Security labels can be made with face materials that have unique fibres embedded in them or paper that has a watermark (during the manufacturing process, a stamp is pressed into the paper which causes variations in the paper's density - when the paper is held up to a lightsource, the watermark appears); printed with special methods such as intaglio printing (the image is incised into the substrate and ink sits in the sunken area rather than on the surface) and microprinting (extremely small text that is invisible to the naked eye); or printed using specialty inks, such as colour change inks (pearlescent pigments that appear as a different colour when viewed from different angles), magnetic inks, or fluorescent inks (visible or invisible in natural light, these inks fluoresce or glow under UV lights or black lights; they absorb and reflect visible light as normal inks do, but also absorb other wavelengths - such as long wave UV - and emit them in longer wavelengths, which the human eye perceives as a glow under UV or black light conditions).Go Back to Glossary
