BLANKING.

If the work is very open, consisting of heads, whites, &c., the

compositor must be particularly attentive to their depth; so that though

the white may be composed of different-sized quadrates, yet their

ultimate depth must be equal to the regular body of the type the work

is done in; otherwise the register of the work will be incomplete. The

pressman cannot make the lines back if the compositor is not careful in

making up his matter.
