METHOD AND DEVICES FOR EVALUATING ELECTRICALLY CONDUCTIVE, PRINTED STRUCTURES UND PRINTING MACHINE HAVING SUCH A DEVICE

摘要

The invention relates to a method for evaluating electrically conductive, printed structures and to a device, particularly for executing such a method, and to a printing machine (4) comprising such a device. The invention provides for the printing of electrically conductive structures, such as transistors, for the production of electronic circuits and a link-line conductivity test, preferably transversal to the running direction of the web material (2) running through the printing machine by means of one or more measuring rollers (11), which are provided with spaced ring electrodes for measuring the electric resistance or also for testing the short circuit strength in contact with the printed electrically conductive structure. The measuring signals are wirelessly transmitted to a receiver device (15) and can also be used in a closed control loop for influencing the printing parameters or the control technology of the printing machine.
