Abstract
Apparatus and methods for controlling application of a substance to a substrate involve the use of a functional agent that blocks the substance from or attracts the principal substance to the substrate. The apparatus and methods may utilize ink jet technology to apply the functional agent directly to the substrate or to an intermediate surface. The principal substance may be an ink, a dye, a marking substance other than an ink, or a carrier for any other type of substance.
