Furthermore, special security threads and foils with transparent and opaque areas can show very brilliant effects in colour (switch) and gloss. Secondly, the “intelligent” combination of security elements allows the creation of new and more complex effects. Registered intaglio overprints of silkscreen printed motifs, special offset printed patterns and diffractive foils can enhance the security of existing elements.
Furthermore, blind embossing of other printed features produces layered, variable images. Nevertheless, for the next series of euro banknotes we need at least one new level 1 security feature that can be used by the ordinary citizen in everyday situations.
