INSTALLATION FOR REGULATING THE SPEED OF DROPLETS IN INK PRINTERS

摘要

Method for regulating the speed of droplets in ink printers which operate according to the principle of underpressure. In the fast devices of that kind, inking errors due to variations in the droplets speed are occurring at the beginning of the droplets sequence, the speed variations resulting from turbulences on the path of the droplets. The installation described in the present invention compensates that phenomenon by regulating the guiding amplitude of the droplets running on an erroneous trajectory.
