Abstract
There is provided by this invention a unique printing system that utilizes a notch deflector in the ink delivery channel of a continuous ink jet printing system to control the angle of deflection ink droplets in a print and non-print direction. The width and depth of the notch in the ink delivery channel can be varied to produce different angles of deflection of the ink droplets for a given velocity of ink through the channel. Also, for any predetermined width and depth of the notch in the ink delivery channel, the deflection angle of the droplets will vary with varying velocities of ink flow. Control circuits are connected to the notch deflector to adjust the depth of the deflector for different angles of deflection.
