Microtext
200 D-Mark banknote (BBk-III series). The font size in the original is 0.25 mm
The microprinting is a printed or embossed font in a size with the font height of less than 0.3 millimeters high, which usually only with a magnifying glass can be perceived. It can only be produced with modern printing templates and printing techniques and is primarily used as a security feature for sensitive printing units, but also in electrical engineering for labeling small components. The purpose of micro-writing as a security feature is that counterfeit copies or color copies of corresponding originals containing micro-writing are only illegible or blurred.
Microtexts have been used for securities , banknotes and documents since the 1980s . There are also areas of application for postage stamps , coins ( Swiss francs , Romanian leu ) and personal documents ( German passport and identity card , Austrian driver's license ). The plastic strips in passports , for example in French and Turkish passports, are sometimes also printed with microscripts in order to guarantee further protection against forgery of the documents.
