Coquille board, also known as stipple board, is a type of drawing paper with a pebbled texture. The grain is impressed into the uncoated paper during manufacture.[1] Used with a soft lithographic crayon or carbon pencil, coquille produces a shading effect similar to hand stippling in a fraction of the time.[2] The material is especially useful for works to be reproduced in print, such as scientific illustration and cartooning.[1][3][4] However, coquille is also delicate and cannot withstand vigorous pressure from an eraser.[2]
It was used extensively during the pulp era to quickly create easily-reproducible print images. By the early 1990's it had been displaced by cheaper halftoning technologies and became difficult to obtain.[5]
