DESCRIPTION  OF THE  PAINTING TECHNIQUES OF THIS EXHIBITION
===============================================================
 

LITHOGRAPH

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.

 

ETCHING

A  zinc or copper plate is being coated with an acid-resistant resin mass
(caustic background). With a sharp steel needle the drawing is being applied
until the metal is uncovered. In the acid bath the exposed parts are being
etched and the longer one leaves it in there, the deeper the lines get. The
deep lines absorb the colour in the print procedure. The pressure is being
applied with a hand press.

 

HELIOEGRAVURE

Procedure to the production of etching on copperplates for the
hand-press deep-printing (copper-print).
At this procedure, the in contrast to the original-graphic
proceeds, how> copperplate or> etching, on photographic
basis is founded, becomes a positive on chrome gelatine-pigment-paper
copies. This pigmentopike becomes on a with melt asphalt-dust
overcast copperplate transfers, the subsequent according to the thickness of the
at the washing out of emerging gelatine-relief, differently is etched.

(SILK) SCREEN PRINT (SERIGRAPHY)


 With the help of a rubber squeeze tool paint is being applied through a
tissue (mostly gauze) fixed on a framework  onto the paper. In order to
produce the chosen drawing the parts that should not printed are being
covered up, whereas the other parts remain colour permeable. The procedure
mostly used is:

- A gelatine layer sensitive to light is applied to the material and exposed
to the light. The parts not exposed will dissolve after the development.
- The drawing is transferred with a fat pencil onto the tissue,  the screen
printer is covered with water soluble glue, which is being rejected by the
drawing which contains fat.
- With glue or lacquer templates are being glued onto the material.
