LITHOGRAPHY

Lithographic printing works on the principle that oil and water do not mix. In this process the non-image area on a plate is treated so it accepts oil, which in turn repels the water based inks that are passed over it, leaving ink only on the image area. This ink is then transferred on to a rubber blanket which will make the impression on the final substrate. Litho printing is one of the easiest print processes in which to achieve pleasing results but it can sometimes give disappointing results with regard to colour saturation and print consistency.
