Method of digital printing

摘要

A method of digital printing in which paint is deposited in metered amounts on a print medium includes providing a paint injector which advances a paint coated strand through the path of a fluid stream. The fluid stream removes the paint from the exterior of the strand and deposits the paint onto the surface of a print medium. The advancement of the strand is selectively controlled to effectively meter the paint applied to the print medium and the position of the paint injector is controlled relative to the print medium to form an image thereon. The paint injector is comprised of a wheel rotatable by a shaft of a motor, an idler at least partially disposed in paint contained in a reservoir, and a wire disposed at least partially around the wheel and the idler.
