Abstract: ElectroInk experiences multiple transfers, some electrostatic and others mechanical, on its way from the ink can to printed image in an HP Indigo press. For example, in the binary ink developer (BID), ink is electrostatically transferred from the developer roller to a metal cleaning roller and then removed from the cleaning roller and returned to the ink tank by mechanical action. The disposition of ink charge following transfer is critical to the performance of the press. Of particular interest are the timescale for ink charge decay following electrostatic transfer and the impact of mechanical transfer on ink charge. Both of these subjects will be addressed in this presentation.
