Abstract:
1. An apparatus for applying first and second gating agents and a principal substance to a substrate to produce an end product, comprising: first and second sources of the first and second gating agents, respectively; first and second sets of nozzles in fluid communication with the first and second sources, respectively; a controller operable to deposit the first and second gating agents independently through each of the first and second sets of nozzles onto the substrate; and means operable after the first and second gating agents have been deposited onto the substrate for applying the principal substance to the substrate in areas defined by the deposited first and second gating agents; wherein the principal substance is applied to a region of the substrate having both the first and second gating agents such that at least one of the first and second gating agents prevents transfer of the principal substance to areas of the substrate having the at least one of the first and second gating agents, and the substrate with the principal substance comprises the end product.
