Alternating current energized printing system utilizing a dielectric covered resilient impression roller |
摘要 |
A printing system where the alternating current energized semiconductive layer of the impression roller has a covering of dielectric material with a controlled thickness, and with a dielectric constant many times greater than that of the web, such that a major portion of the applied electric potential is transmitted to the web by means of a reactive current through the covering.
