Abstract
A method of controlling excessive electroforming portion of an oscillating plate for an ink-jet printer includes steps of supplying a direct current power to electroform a first layer for a first time period, supplying an alternating current power to electroform a second layer on the first layer for a second time period to form an oscillating layer, coating the second layer with a photoresistive agent at positions where no projection is to be formed and supplying the alternating current power to electroform for a third time period so as to form desired projections on the second layer, whereby no excessive electroforming portion will be formed on the projections.
