Modification 2010:Ī diffractive optically variable device. Hidden Multi Coloured image under UV light.

When the banknote is rotated without changing the angle of view, each character changes its colour (fig. Each character of the value numeral has its own colour. When the banknote is tilted under UV light, the image may appear on the one-coloured area of the banknote. Each character of the image has its own colour. When the banknote is tilted, the image appears on the one-coloured area of the banknote. Gravure printing is used in the manufacturing process of the banknotes on the polymer substrate.Īn image made by colorless embossing over a printed area on the banknote. Zoomed fragment printed by gravure printing.Ī – raster lines of spacing elements b – notched edge of the image raster lines of spacing elements may be seen in the places of light halftones (fig.absence of outlined contours or lines (fig.The characteristic features of the prints:

The ink is transferred under contact pressure from the printing elements to the substrate. Then a special knife (scraper), sliding along the plate surface, removes totally the ink from the spacing elements and its excess from the printing elements. During the printing process, first of all a low-viscosity ink is applied in plenty over the whole surface of the rotating plate. The printing plate is made on the cylinder. These dividers and other spacing elements rise and lie on the same level. A printing technique from a plate, where printing elements are incised into the surface and consist of very small cells separated by thin dividers (raster cells) regardless of the type of the image (a text or an illustration).
