Money, cheques and other securities are most often the targets of counterfeiting. That is the reason why they contain the most modern graphic protection against counterfeiting. Protection elements are not only various techniques of printing with various toners, water stamps and holograms, but also the very paper from which securities are produced. When banknotes are produced, various protection elements are designed in order to prevent counterfeiting. The more numerous and newly designed protection elements there are on a banknote, the less chance there is for producing a competitive counterfeit. When there is a greater number of various types of protection, counterfeiting becomes more expensive, and therefore it lessens counterfeiting attempts. The most frequent and the most noticeable types of protection are: the water stamp, various types of printed matter visible or invisible to the bare eyes, holograms. One of the ways how to protect securities is uneven paper thickness on the overall securities area. This paper shows the results of investigating paper roughness and uneven thickness that have been produced on purpose in order to protect securities against counterfeiting. Estimates are given and recommendations for planning paper choice for this specific graphics production area.
