KURZE BESCHREIBUNG DER  MALTECHNIKEN IN DIESER KUNSTAUSSTELLUNG

LITHOGRAFIE
Die Zeichnung wird mit fetthaltiger Kreide auf eine Kalksteinplatte gemalt. Die nachdruckenden Partien werden so präpariert, dass sie Fett abstoßen (meist durch Einwirken von Säure). Die Zeichnung wird abgewaschen, nur der Fettgrund bleibt erhalten.

The drawing is being painted on a limestone slab with chalk which contains fat. The parts to be printed lateron are being prepared, so that they reject fat (mostly through the effect of acid). The drawing is washed off, only the fat background remains.

Printing process:
- The stone is moistened, the fatty parts reject the water.
- The stone is being  rolled in fat containing colour which sticks at the fatty parts and is being rejected by the moist parts of the stone.
- Print paper is being put on the stone.
- Pressure is being produced in the lithographic press.

Coloured prints are possible to produce, however, one requires a special stone for each colour.
