PURPOSE:To obtain a printing pressure displayer for an off-set printer, which is capable of exactly and easily detecting the magnitude of printing pressure, by using a system in which a distance detector is supported in the face of the periphery of a bearer by a supporting arm provided to a printing cylinder bearing, and the variation of the periphery of the bearer is detected. CONSTITUTION:Supporting arms 17 and 17' projecting on the opposite side of the printing pressure-receiving side of a printing cylinder 1 are provided to printing cylinder bearings 4 and 4', and by the supporting arms 17 and 17', distance detectors 18 and 18' are supported in the face of the peripheries of bearers 12 and 12'. The variation in the distance between the distance E and E' detectors 18 and 18' and the peripheries of the bearers is detected, converted into printing pressures, and displayed. |
