Security shiny dots are highly luminescent, invisible particles. The particles are carefully classified according to size and then are transferred to the paper during its manufacturing. These dots may have different fluorescent colours (e.g. blue, green, red). The use of material significantly enhances the security level of the document. Since not only luminescent materials can be incorporated in the particles, additional hidden elements can be applied in the security paper. The application of this security feature offers many advantages compared to traditional fluorescent paper additives.
