Screen printing

A method for screen printing using a screen, preferably a metal screen made by electroforming, having a pattern of openings separated by bridges and crossing points, and having a flat surface on the squeegee side, wherein on the printing side of the screen the screen has a 3-D structure comprising peaks (P) and valleys (V) formed by a difference in thickness between the bridges and crossing points. The use of the method in the production of RFID tags, solar panels, electronic printing boards. A 3-D printing screen, with an attached stencil with or without the negative of an image to be printed. A printing machine comprising: one or more 3-D printing screens, in combination with one or more reservoirs for ink and/or in combination with a roller or squeegee.

Screen plate

A screen plate for screen printing is provided with a plate frame, a supporting body screen having an outer peripheral part fixed to the plate frame, and a printing screen having an outer peripheral part fixed to the supporting body screen. The supporting body screen is made of an n/m twilled weave textile, wherein n and m independently represent an integer of 2 or more. The screen plate has excellent printing accuracy.

Printing stencil for producing a structure of an electronic component, in particular of a photovoltaic solar cell, and method for producing a printing stencil of this type

A printing form for producing a structure of an electronic component, in particular a photovoltaic solar cell, having a screen frame and a screen, which is in the form of a sheet-like textile and has a multiplicity of elongate screen elements. The screen is arranged in the screen frame and the screen has at least one printing region which a printing paste can permeate and at least one barrier region which the printing paste cannot permeate. The elongate screen elements are made from glass fiber, carbon fiber and/or carbon nanotubes.
