N.B. Infrared visible inks are available in readable and disappearing ink, meaning that when printed they can look the same but when viewed under infrared light, one will be readable and one will disappear. One example of using these two inks as a security feature would be to print a bar code using both inks. Print the actual readable area of the bar code with the infrared readable ink and other areas of the bar code with the infrared disappearing ink but making it look like a regular bar code. When read by a bar code scanner, only the infrared readable is read by the scanner. If a forger tries to duplicate the bar code as it looks on the printed document, using regular inks, the bar code would be rejected when read by the scanner because the scanner would read the entire bar code. Visible infrared ink is available for wet or dry offset printing.
Description Some IR inks can be invisible to the naked eye under normal lighting conditions, requires a specific reader to detect and to view it (infrared emission source).
 
Strengths Can deter simple attempts at counterfeiting (such as color photocopying);

Can trick counterfeiters when combined with other inks to form a barcode cf. NB;
