This pattern of closely spaced lines can be seen when the paper is held up to light. Laid paper often has a watermark. Wove paper is made by machine on a belt and lacks the laid lines. False laid lines can be added to machine-made paper. Though wove paper was invented in the eighteenth century and laid paper is still produced, the majority of prints made prior to 1800 are on laid paper and the majority of prints made subsequently are on wove paper.
China paper is a very thin paper, originally made in China, which is used for chine applique prints.
Photomechanical prints Prints made from photographically prepared printing surfaces. A distinctive dot pattern is usually visible. Platemark A platemark is the rectangular ridge created in the paper of a print by the edge of an intaglio plate. Unlike a relief or planographic print, an intaglio print is printed under considerable pressure, thus creating the platemark when the paper is forced together with the plate. Some reproductions have a false platemark.
