Proofreading Marks

校正記号 / 16th century– / Technique / Symbol Systems

A sign language that corrects a typeset page through dialogue with its margins. The back-and-forth of deletion and stet, and the Western dele, were refined alongside the history of printing into an editing protocol that stands behind every typeset work, this dictionary included.

Dictionary entry

Type
Corrections in red and queries in pencil, one color per person
Composition
Lead lines run from the text out to the margin without crossing
Material
Proofs printed at full size with margins wide enough to write in
Caution
Corrections written as prose instead of marks leave the extent of each change open to reading, and every pass introduces fresh errors.
