Plates
Metal plates: Generally, the plates used in offset printing are thin, flexible, and usually larger than the paper size to be printed, and are usually made of aluminum, although sometimes they are made of multimetal, paper, or plastic.
Polyester plates: These are much cheaper and can be used in place of aluminum plates for smaller formats or medium quality jobs, as their dimensional stability is lower.

“Behold now this vast city; a city of refuge, the mansion house of liberty, encompassed and surrounded with his protection; the shop of war hath not there more anvils and hammers waking, to fashion out the plates and instruments of armed justice in defence of beleaguered truth, than there be pens and hands there, sitting by their studious lamps, musing, searching, revolving new notions.”
—John Milton (1608–1674)

“What I’ll be seeing more of in the years
To come as here I stand and go the round
Of many plates with towels many times.””
