Abstract
The invention relates to a method of the dosed application of a liquid onto to selected portion of the surface of a substrate (A) by means of spraying under the influence of an electric current. According to the invention the liquid is fed at a flow rate between 0.01 pl/s and 1 ml/s to a distal tip () of a capillary () having an inside diameter of less than 150 μm, wherein the distance between the distal tip and the surface (A) is less than 2 mm. Surprisingly it has been shown that it is possible in this manner to apply liquid to a restricted surface of a defined size.
