Noun.
Short for lithography. "Litho" can refer to the printmaking technique itself or to a print that was made using this technique.
Adjective. To describe anything printed using lithography.
The term "litho" is generally only used in art schools (
teachers and students), or by graduates and
drop-outs from art schools. Granted, not every art student even knows what it means, but they invariably recognize it as an art school term.
"Is this what they
mean by a woodcut?"
"No, this one is litho. That one over there is intaglio. And
the one on your
shirt is silkscreen."
"What's the difference?!"
"They're all prints. But I used different techniques to make 'em."
