What is Silkscreen Printing?
Silk screen printing is printing with the use of a silk mesh screen which is placed over the paper being printed on to, and ink being pushed through the mesh of the screen in order to deposit a thin and even layer of colour on to the paper. Shapes are masked off in order to only print ink on to the desired areas of your paper. Multi layering of inks on a single sheet of paper with different shapes masked off could create rich, densely coloured images. Silk screen prnting is a quick way of exploring colour and colour theory, and also a very effective means of mass production of a single image.
What is Etching?
Etching works on the same principles as other relief printing - it is the process by which an image is burnt into a metal (usually copper) plate by being exposed to acid, which bites into the lines of the image (the areas of the drawing that should not be bitten into by the acid are masked off with an acid resistant material, such as stopout varnish. Printing is then done by inking the bitten plate up and applying pressure on to the plate as it lies face down on a sheet of paper. Etchings are best printed using a printing press.
What is Lino and Block Printing?
Also known as relief printing or woodcut printing depending on the materials being used, block printing is when an images is cut away from a block. What remains forms the positive shapes and lines of your image. Most commonly the material being cut into is lino or wood. Once the image has been fully cut into the block, ink is rolled on to the surface in a thin and even manner, and then paper is pressed on to the inked up block in order to make the print.
