Designing banknotes is an enormous challenge that demands creativity and aesthetics on the one hand and experience, perfection and knowledge of security techniques on the other. Robert Kalina, designer of the current series of euro banknotes, offers a brief introduction to the world of banknote design. Robert Kalina graduated from the Höheren Graphischen Bundes- Lehr- und Versuchsanstalt (Vienna) in 1975. He subsequently joined OeSB (as it is known today) where he designed all ATS banknotes issued since 1982. OeSB, the former state security printer, designs and prints banknotes on behalf of a number of government authorities. Robert was mandated by the European Central Bank to design the current series of EUR banknotes (1996). He is married and has two children.
