What does copperplate mean?
Copperplate refers primarily to a sheet of polished copper incised with lines holding ink, used in intaglio printing: the recessed engraved lines are filled, surplus ink wiped away, and damp paper pressed against the plate to lift a crisp impression. Prints pulled this way are themselves often described as copperplates or copperplate engravings, and the technique dominated fine art reproduction, maps, and banknotes from the sixteenth century until cheaper steel-facing and lithography displaced it in the nineteenth. The word also names an elegant, round-handed style of calligraphy: because engravers cut flowing, slanted letterforms onto plates for copybooks, schoolchildren learned to imitate them with a flexible nib, giving rise to what is still called copperplate script. Today the term survives mainly among printmakers, collectors, historians, and calligraphers, where it signals craftsmanship, precision, and a certain old-world formality.

Etymology of copperplate
The word is a straightforward English compound of 'copper' and 'plate', first recorded in the seventeenth century as engravers adopted copper as their preferred intaglio surface. 'Copper' traces back through Old English 'copor' to late Latin 'cuprum', a contraction of 'aes Cyprium' ('metal of Cyprus'), while 'plate' comes via Old French from Greek 'platys', meaning flat or broad. The calligraphic sense developed later, in the eighteenth and nineteenth centuries, when engraved copybooks spread the lettering style that came to bear the plate's name.
How copperplate is actually used
The noun senses (printing plate and its impression) are technical and mostly confined to printmaking and book-history contexts. The writing-style sense is usually encountered attributively — 'copperplate hand', 'copperplate script' — rather than as a standalone noun, and carries connotations of formality, elegance, and traditional education.
