Abstract
In order to increase at least the adherence of lacquer on a workpiece surface consisting of at least substantially one synthetic, organic polymer, which workpiece is plasma treated in an environment of reactive gas, the treatment duration is selected at least close to an adherence maximum in a lacquer adherence-/treatment duration diagram and/or the gas pressure at least close to an adherence maximum in a lacquer adherence-/gas pressure diagram.

A method for plasma treating a surface of a workpiece during a treatment duration and in an environment of reactive gas at a gas pressure, in order to increase an adherence of a lacquer to the surface, the surface consisting essentially of at least one synthetic, organic polymer, the method comprising:
- selecting at least one of, the duration for the treatment, and the gas pressure for the reactive gas, such that if the duration is selected, the selected duration is within a range corresponding to a substantially flat region of an adherence maximum of a lacquer in a lacquer adherence-treatment duration diagram, and such that if the gas pressure is selected, the selected gas pressure is within a range corresponding to a substantially flat range of an adherence maximum of a lacquer in a lacquer adherence-gas pressure diagram;
- and
- plasma treating the surface of a workpiece following the at least one of the selected duration and selected gas pressure.
