Vitreography:
This is the term given to prints created from a glass sheet. Vitreography prints are intaglio (from the Italian for “below the surface”) because the glass surface is scratched, etched and abraded and inked in such a way that the glass surface remains clean whilst the ink is held in all the surface marks, and which via high pressure through a press is transferred to
dampened quality paper. The glass used must be both thick and even: typically 10mm float glass. Prints made in this process are characterised by a soft light colouration, with a distinctive embossed frame.
