A method and a device for detecting and controlling the printing pressure for a flexographic machine having at least one printing group comprising first ink supply means, a second cylinder capable of removing a quantity of ink from said first supply means, a third cylinder rotatable and provided on its periphery with at least one covering element, the peripheral surface of which is defined by portions reproducing the motif to be printed, and a fourth cylinder defining, together with the third cylinder, a passage for the transit of a strip of material on which printing is to be performed; the cylindrical surface of the third cylinder has connected to it at least one sensor element for emitting signals proportional to the forces with which the sensor element itself is stressed during the course of contact of the portion of the third cylinder with the strip and with the second cylinder.
