The decals and reference designators in epoxy ink on a printed circuit board so called because of the method of application - the ink is "squeegeed" through a silk screen, the same technique used in the printed of T-shirts. Silkscreen information can include component identifiers, component reference designators, company logos, switch settings, test points, other instructions, part numbers, version numbers, etc.
