colored paper
Paper colored on one or both sides during
manufacture by means of coloring pigments. When
its use is to be for cover papers, endpapers,
etc., the shade may range from light to very dark;
for printing purposes, however, the usual colors
are the light shades, since a dark ink is not very
legible on too dark a paper. and printing very
light inks on dark paper is not generally
practical as two impressions are usually required
to obtain adequate opacity. Duplex papers are
those with different colors on the two sides of
the sheet. ( , 204 )
