The main printing techniques are screen printing, block printing and photocopying. Letterpress, lithography, flexography, and gravure printing are used in commercial manufacturing. Finishing techniques enhance the final product. Different packaging materials perform different functions. There is certain information that must be provided on packaging by law.
Prints in color require two or more blocks, plates, screens or stones, one for each color, printed sequentially on top of each other to produce the final work of art. This process is called registration. Prints can be classified according to the type of surface used to make them. Those with raised printing surfaces are known as relief prints; woodcuts are the most common type of relief print. When the printing surface is below the surface of the plate, the print technique is classified as intaglio. There are several important intaglio techniques. Planographic and stencil methods are also used, and print from a surface that is at the same level as the non-printing surface.
