clay-finished paper
A paper, such as imitation art paper, coated with
finely pulverized clay to impart a smooth finish
suitable for halftone illustrations. Such papers
present difficulty in binding, as they are
difficult to sew (especially to oversew), and
there is often the tendency for the clay to
separate from the base paper, especially under
humid circumstances or if the paper becomes wet.
In addition, they are unusually stiff and
frequently must be scored. (52 , 278 )
