| UV Detection: | At bank notes and other securities printing they use fluorescent dyes, i.e., dyes capable to glow under exposure to UV-radiation. To give a dye such a property, they add special components into it - luminescent solids that do not glow in natural light, but under exposure to UV-radiation there appears luminescence of one or other colour called fluorescence. | ||||||
| Magnetic Detection: | During bank notes printing they use dyes with magnetic properties that appear after adding some ferromagnetic components into a dye. Such a dye can be detected by means of magnetic image visualizers or by testers with magnetic head. They often print serial numbers or fragments of metallographic picture with a magnetic dye. | ||||||
| Water Mark: | A watermark is a recognizable image or pattern in paper that appears as various shades of lightness/darkness when viewed by transmitted light (or when viewed by reflected light, atop a dark background), caused by thickness variations in the paper | ||||||
