The present invention relates to the technical field of security documents comprising a security feature, such as a windowed security thread, a security foil, a security patch, a hologram or an ink printed security feature, and a protective coating, and methods of manufacturing of said security documents. The security feature has a security feature thickness t.sub.f of at least about 5 μm (micrometers) and a security feature surface facing away from the substrate consisting of a first region adjacent to the edges of the security feature and a second region non-adjacent to the edges of the security feature. The protective coating covers the security feature surface facing away from the substrate, a first substrate surface adjacent to the edges of the security feature, and a second substrate surface, which is different from the substrate surface covered by the security feature and the first substrate surface. The protective coating covering the security feature surface facing away from the substrate and the first substrate surface is transparent, the protective coating covering the first region has a thickness t.sub.b1, the protective coating covering the second region has a thickness t.sub.b2, the protective coating covering the first substrate surface has a thickness t.sub.c, and the protective coating covering the second substrate surface has a thickness t.sub.a. The thickness t.sub.c is larger than the thickness t.sub.f, which is larger than the thickness t.sub.a; the thickness t.sub.b2 is larger than the thickness t.sub.a; and either the thickness t.sub.c is larger than the thickness t.sub.b1, which is larger than or equal to the thickness t.sub.b2; or the thickness t.sub.c is equal to the thickness t.sub.b1, which is larger than the thickness t.sub.b2. The variable protective coating thickness on the surface of the security document provides the inventive security document with an increased resistance against physical and chemical attacks from the environment, while maintaining the mechanical resistance properties required for such security documents.

Systems and methods for using a non-stick conductive material to automate tool touch-off in an additive manufacturing process are provided. A substrate comprises a first conductive layer, an intermediate binder layer, and a second non-stick conductive layer. The non-stick conductive layer may comprise perfluoroalkoxy alkanes and carbon nanotubes. An electrical connection may be made between the first conductive layer and the second non-stick conductive layer. When used with an additive manufacturing device, when the nozzle of the device contacts the substrate, a circuit may close resulting in a detectable voltage drop. When the voltage drop is detected, a reference point for the additive manufacturing device may be set.
