Only after 1945 do artists start to use the silkscreen technique as an artistic medium. The principle is based on the use of stencils. On a frame, covered with a fine-meshed nylon cloth, a thin photo film is applied. Once it has dried, a transparent foil with a drawing is placed on the silkscreen frame. It is illuminated, after which the frame is spayed with water. On the places where the picture has lain on the wire-mesh cloth the water dissolves the emulsion and there the ink can pass through.
After the drying process the frame is attached to the serigraph table with clamps. Using a squeegee the artist forces the ink through the screen onto the paper. In the serigraph technique each pass of the squeegee produces on the printing surface an unreversed duplicate of the original design. The carrier may be paper, but glass, metals or plastics can also be printed.
In contrast to other printing techniques the edition is in principle unlimited. Characteristic of a serigraph is a thick layer of ink and large uniform colored areas.
