Mimeograph

The mimeographing is a screen printing method in which a fibrous web, for example by printing of letters, a farbstoffundurchlässige layer is removed. This matrix serves as a mirror image between the original and is stretched to a pressure cylinder, which can hold at the points where the farbstoffundurchlässige layer was removed, ink and press onto paper to print.

This process initially allowed although longer runs than the hitherto widespread copying press, but has been replaced quickly by other copying techniques, such as the soon emerging Hektographie and much later by photocopier.
