1. A printing process for obtaining patterns of nanometer and micrometer dimensions on a substrate, comprising the steps of
sequentially:
forming a solution or suspension of a volatile liquid and a printing material,
applying a layer of the solution or suspension to said substrate,
positioning, without applying pressure, of a stamp provided with relief patterns at a distance of 0 nm to 500 μm from the
substrate with the relief patterns in contact with the layer of the solution or suspension,
evaporating only the volatile liquid from said solution or suspension from between the substrate and the stamp without evaporating
the printing material so as to draw the suspension or solution by capillarity to the relief patterns and deposit the printing
material on the substrate in accordance with the relief patterns of the stamp, and
thereafter separating the stamp from the substrate and leaving the printing material on the substrate.
