This colouring process - sometimes also referred to as Orlof (Orlov) process - is used in intaglio printing and enables more than one colour to be printed simultaneously and accurately with one printing plate. A modern printing press can often print several colours (e.g. 3, 4, or 5). The individual colours are applied via individual stencils that match the elements or parts of the required final design. These stencils are also referred to as schablons (or chablons). The inks may overlap to a small extent and in the final printed image a slight colour transition can therefore be seen. The colour transitions need not, as in rainbow colouring (offset printing), run parallel to the direction of printing.
