1. A method of producing an accurately positioned white layer to serve as an undercoat for inkjet process colors imaging on a substrate, comprising the steps of:
- accurately ink jetting a colorless loosely-bonded frame onto the substrate, said frame defining an area to be imaged; and
ink jetting or spraying a white layer, said white layer at least partially overlapping said frame and said white layer covering said area defined by said frame.
