Lithography is a printing process that, traditionally, uses a flat stone on which the image areas are worked using a greasy substance so that the ink will adhere to them by, while the non-image areas are made ink-repellent.
Lithography was invented in the late eighteenth century, initially using Bavarian limestone as the printing surface. Its invention made it possible to print a much wider range of marks and areas of tone than possible with earlier printmaking relief or intaglio methods.
Waterless Lithography at Green Door
The innovative technique we use at Green Door, called Waterless Lithography, was developed by Professor Nik Semenoff and offers a greater flexibility of expression for a fraction of the cost of materials.
This process is also safer for the artist than traditional stone lithography as it does not involve the use of acids, instead operating on the basis that ordinary silicone rubber acts as an ink rejecting surface.
