means A printing method that transfers images from a flat surface — originally greasy ink on stone — onto paper, based on the simple fact that oil and water refuse to mix.

from Coined from Greek *lithos* (stone) + *graphein* (to write), literally 'stone-writing' — because that's exactly what it was. Invented in the late 1700s by Alois Senefelder, who stumbled onto the technique while looking for a cheap way to print his plays, using a greasy crayon on limestone slabs to draw an image that would hold ink while the wet, blank areas repelled it. The name stuck even as the stone itself eventually left the process entirely — modern offset and photolithography (the backbone of microchip manufacturing) kept the word long after the slabs were gone.
