Abstract
This invention relates to a plastic substrate production process, the production device for such a substrate, and the use of the process for the production of integrated circuit boards. The plastic substrate production process is characterized in that it comprises the following steps: unwinding and straightening of a continuous strip of plastic which is slightly larger in dimension than one of the dimensions of the board; printing, at at least one printing station, of a series of printing patterns and of printed markings; driving of the strip at a regulated printing speed; detection of the difference in speed; cutting by a press of the strip at positions defined by the printed markings; and regulation of the printing speed as a function of the difference between the printing speed and the driving speed.
