Apparatus and methods for controlling application of a substance to a substrate involve the use of a gating agent that blocks the substance from or attracts the substance to the substrate. The apparatus and methods may utilize ink jet technology to apply the gating agent directly to the substrate or to an intermediate surface. The substance may be an ink, an electrically conductive material, a magnetic material, a carrier for a therapeutic, diagnostic, or marking substance other than an ink, or a carrier for any other type of substance. L'invention concerne des appareils et des procédés de commande d'une application d'une substance sur un substrat, comprenant l'utilisation d'un agent formant barrière qui bloque la substance provenant du substrat, ou attire la substance vers celui-ci. Les appareils et les procédés peuvent utiliser une technologie de jet d'encre pour appliquer l'agent formant barrière directement sur le substrat ou sur une surface intermédiaire. La substance peut être de l'encre, un matériau électriquement conducteur, un matériau magnétique, un support pour une substance thérapeutique, diagnostique, ou de marquage autre que de l'encre, ou un support pour tout autre type de substance.
