Security features are achieved through these methods: Microtext, Raster special ghilose, simulations relief antiscanare graphics, etc. line with variable thickness. Fine guillouches are complex, consisting of continuous lines cross, arranged in geometric patterns.
Background design drawings ghilose meet other fine line (rosettes), with the aim of raising the recreation and reproduction.
