    Patent number: 11056638
    Abstract: A method for manufacturing an inkjet print head includes determining a misfit strain-electric field crystal phase relation for at least one composition of a piezoelectric material; selecting a misfit strain value and a composition of the piezoelectric material based on the determined misfit strain-electric field crystal phase relation for said at least one composition; and based on the selected misfit strain and the selected composition of the piezoelectric material, forming a base layer and an actuator stack on the base layer, the actuator stack including the piezoelectric material, wherein the base layer and the actuator stack have predetermined properties providing the selected misfit strain value and the selected composition. Thus, an inkjet print head having a piezoelectric actuator that is operated on the basis of a crystal phase change is reliably manufacturable.

  • Metal photographic plate with carrier and method of use
    Patent number: 10987947
    Abstract: This disclosure provides a solution to the problem of metal printing where the printer leaves an undesired “border” or “margin” around the edge, as the printer sensors detect the edge of the metal plate and stop printing before reaching the edge. The system and method disclosed herein comprises a metal plate removably associated with a carrier, where the carrier is larger than the metal plate such that the metal plate is positioned entirely within the perimeter of the carrier. The metal plate has a special receptive coating that allows ink from an inkjet printer to adhere to the metal plate without running. The carrier has an external coating that mimics the metal plate such that the sensors of the printer do not detect any “edge” of the metal plate and print over, onto the carrier. This creates a borderless final printed picture.
