Technique and condition
Colour lithograph printed on off-white wove paper made in 1971. Printed in two-colour blue ink, the image consists of a dispersion of watery inks printed across the whole paper support. Lithography is a planographic technique based on the chemical resistance of oil and water. The image is applied to a grained aluminium plate (historically Bavarian Limestone) using a greasy ink (tusche) or crayon. The plate (or stone) is then etched by a wash of acid and gum arabic, which fixes the image and makes the blank surface receptive to water. When ink is rolled over the surface it adheres to the artist's marks, but is repelled from the rest of the surface. Paper is then placed against its surface and the plate is run through a press. The print is inscribed in pencil towards the bottom of the image with the artists signature and edition number, sixty seven from an edition of sixty nine. Framed in a metal frame, polished aluminium and float mounted. On acquisition the print is in good condition.
