The electrostatic printing method of the present invention comprises arranging and adhering an original plate which is composed of an electrode and a plate layer having built-in a letterpress, intaglio plate, or gravure plate pattern or a mask sheet having ion-permeable openings on one or both sides of an image receiving sheet having an electrode and an image receiving layer, and forming a predetermined electrostatic pattern on the image receiving layer of the image receiving sheet by applying a voltage between the electrode of the original plate and the electrode of the image receiving sheet or by performing ion irradiation through the mask sheet.

A powder film forming method includes the steps of: filling an opening with a powder, the opening being formed in a screen plate; and forming the powder film by generating an electric potential difference between the screen plate and a substrate so as to cause the powder, which is filling the opening, to move to the substrate.

A method for manufacturing an optical element comprising a fine pattern over a substrate. Further, the method comprises: preparing the substrate comprising an uneven structure on a surface of the substrate, the uneven structure comprising recesses for the fine pattern; applying functional ink to the recesses; obtaining the optical element comprising the fine pattern made from the functional ink in the recesses.

A screen printing device and a screen printing method are provided. The screen printing device includes a screen plate and an electrifying device, the screen plate includes a conductive mesh; and the electrifying device is electrically connected with the conductive mesh and configured to apply voltage to the conductive mesh. The screen printing method includes: adopting a printing head to rub against a screen plate to print ink onto a substrate for silk screen printing, wherein the screen plate includes a conductive mesh; and applying voltage with positive or negative polarity to the conductive mesh in the screen printing process.

A charge storage cell includes a substrate having a back side conductive layer or conductive element, a top side metal pad coupled to the substrate, and an insulating layer formed on the metal pad. The metal pad will support an electric charge injected through the insulating layer by a charged particle beam. A regular array of charge storage cells provides a charge storage array.

A method for performing laser-ablation printing may include (i) determining an image to be printed on a printing substrate; (ii) ablating a printing material to expel a plurality of ablated printing material particles from a surface of the printing material; (iii) electrically charging the ablated printing material particles; and (iv) accelerating the electrically charged ablated printing material particles toward the printing substrate so that the accelerated particles are deposited on the printing substrate in a pattern that corresponds to the determined image.
