USING CONTINUOUS SPRAY INKJET SYSTEM FOR ACCURATELY PRINTING TITANIUM OXIDE BASED INKS

摘要

Method and apparatus for producing an accurately positioned white layer (40) to serve as an undercoat for inkjet process colors imaging on a substrate, by accurately ink jetting a colorless loosely-bonded frame onto the substrate, thereby defining an area (30) to be imaged, ink jetting or spraying a white layer (40), the white layer at least partially overlapping the frame and covering the area (30) defined by the frame.
