CHANGE OF SIZE.

In reproducing wood-cut prints, the size can often be considerably

reduced; but if the reduction is great, the lines become so fine and

close together that they will not print well. Coarse wood-cuts, such

as are generally used in Newspapers, may often be reduced to half

their linear dimensions, but _fine_ wood-cuts will admit of but little

reduction.

_Most_ steel plate prints and lithographs will not admit of any

reduction, and even when reproduced, the same size in relief, require

considerable care in printing.

All kinds of prints generally look bad when much enlarged, as the

lines become very coarse and ragged on the edges; though we have

sometimes made very effective cuts for posters and hand-bills in this

way.

In all cases of enlargement and reduction the relative proportions

remain the same.

It must not be forgotten, however, that by redrawing, prints of any

kind can be enlarged or reduced to any desired size.
