An apparatus for treating the surfaces of formed plastic articles including a plurality of bare metal discharge electrodes connected to a high frequency AC power supply, a counterelectrode disposed in spaced relation to the discharge electrodes for defining a treatment zone therebetween, and an insulation layer mounted in spaced relation to the counterelectrode such that a discreet air space exists between the insulation and counterelectrode for moderating the electrical discharge between the discharge electrodes and counterelectrode and enabling greater control and uniformity in the electrical discharge between the electrodes and counterelectrodes. In the illustrated the embodiment, a first set of discharge electrodes define a first treatment zone for treating one-half of the circumferential surface of articles directed through the first treatment zone and a second set of discharge electrodes define a second treatment zone for an treating opposite peripheral half of the circumferential surface of articles passing through the second treatment zone.

An ink pump system includes an ink reservoir and an ink solvent reservoir from which solvent is controllably transferred into the ink in the reservoir so as to maintain the desired ink viscosity. The ink reservoir has an ink outlet for discharging ink to a point of consumption and an inlet into which excess ink may be recirculated to the ink reservoir. A seal-less gear pump is submerged in the ink reservoir. The pump includes a housing with an inlet communicating with the interior of the ink reservoir so as to receive ink from the ink contents in the reservoir. The pump housing also has a discharge outlet communicating with the ink outlet of the reservoir. The power source for drawing the recirculating gear pump can also be used to drive a paddle which stirs the ink in the reservoir.
