Abstract
The start of each cycle of a pump, which supplies a pressurized ink stream through a nozzle for application to a recording surface on a rotary drum, is synchronized with each revolution of the drum. If more than one cycle of the pump occurs during each revolution of the drum, the number of the cycles in each drum revolution must be an integer with each cycle starting an equal angle of the revolution of the drum from the start of the prior cycle.
