Abstract
A method of partially imaging an imaging surface of a substrate (50) with a plurality of layers of marking material (10) which have at least one common boundary within a print pattern that covers only certain portions of the substrate and not other portions of the substrate. The method includes applying initial superimposed layer of marking material (10) to a base layer (23) and removing portions of the initial superimposed layers of marking material and leaving the desired residual layer portions in the desired print pattern directly applied to the imaging surface of the substrate. The method typically includes the transfer of marking material onto the imaging surface of the substrate. The method has many variants, which can be used to make one-way or other vision control panels, typically using a ceramic ink decal carrier to image a glass sheet with ceramic ink that is then fused onto the glass, which is optionally tempered, in a suitable furnace. Other uses include security printing, seals and labels and a variety of display panels.
