Printmaking
1. The 4 types of printmaking:
a. Relief – a piece of wood or linoleum is cut away with a sharp tool so that only the raised portion of the wood or linoleum can be seen on the paper. An example of this is with stamps.
b. Intaglio - the lowered areas are printed. A substance called the ‘ground’ covers the copper or zinc sheet. An etching tool is used to expose the metal while drawing the picture. The sheet is then dropped in acid, thick ink is rubbed into the grooves, and then a damp paper is placed on top and run through a press. An example of this is with currency (dollar bills).
c. Lithography – the greasy areas of a stone will print. The artist draws the image with a greasy crayon on a flat stone slab. Then the artist rolls ink onto the wet stone, meaning the ink will only stick to the greasy marks and then the artist can make the print.
d. Stencil – the open areas will print. A screen is pulled across a frame, then either using a hand-cut print, painted with tusche or using photosensitive emulsion an opening is created in the screen where the ink can pass through the screen and create an image on the paper or t-shirt below it.
2. Lithography relies on the general principle that water and oil reply each other. To begin, the artist draws the image using a greasy crayon on a flat stone. The artist then rubs a thin layer of water onto the stone. Ink is then placed all over the stone so that the ink is only attracted to the greasy image. The print can then be made by placing the paper on the stone and putting it through a press.
3. The biggest difference between silk screen and etching is that with silk screen, the image is not a mirror image as it is with etching. In addition to etching you can control the tone, the texture and have much greater detail than you can with silk screen. Etching always produces prints that are in black in white, unlike silk screen where you can have various colors.
