For making detail drawings an inferior paper is used, termed Cartridge; this answers for line drawings, but it will not take colours or tints perfectly. Continuous cartridge paper is also much used for full-sized mechanical details, and some other purposes. It is made uniformly 53 in. wide, and may be had of any length by the yard, up to 300 yd. For plans of considerable size, mounted paper is used, or the drawings are afterwards occasionally mounted on canvas or linen.
