INDENT. To set a line some distance forward, as in the case of a new
paragraph.

LETTERPRESS. Printed matter from type as distinguished from plate
printing.

MAKE-UP. To measure off type matter into pages.

OFF-SET. It frequently occurs that as the result of insufficient drying
or from other causes the impression of one sheet appears on the back of

OVERLAYS. In making ready for the press the pressman finds it necessary
to add here and there, by pasting, thicknesses of paper to his roller to
bring out properly the light and shade of an illustration or to get an
even ink impression from the type or plates. This work is called _making
overlays_. In expensive illustrated work specialists are engaged solely
for the purpose of making overlays.

PRESS PROOF. The final proof passed by the author or publisher.

PROCESS-BLOCKS. Blocks produced by the photoengraving and other

QUERY. A mark made on a proof by the printer to call attention to a
possible error, sometimes expressed by a note of interrogation (?).

REGISTER. The exact adjustment of pages back to back in printing the
second side of a sheet.

SIGNATURE. The letter or figure at the foot of a sheet to guide the
binder in folding; also used by printers to identify any particular
sheet.

The various marks and signs used by printers will be explained in the
lesson on proof-reading.
