A screen printing device is provided having a printing screen, a printing squeegee and a support for printing material to be printed. At least one articulated arm robot is provided to move the printing squeegee and/or the support in relation to the printing screen.

The present disclosure discloses a printing machine. The printing machine includes a carrying platform for carrying a to-be-printed board, a frame above the carrying platform, a roller-shaped screen printing plate with printing graphic meshes, and an ink supply device within the roller-shaped screen printing plate. The roller-shaped screen printing plate is mounted to the frame in a manner that the roller-shaped screen printing plate is capable of rotating relative to the carrying platform.

A direct to mesh (DtM) screen printer for creating a screen stencil is provided. The DtM screen printer includes a fixture to hold a frame, which holds a pre-stretched mesh in place during application of a jettable emulsion, a platen having a cavity and an array of holes in a top surface of the platen and is located against one side of the pre-stretched mesh, and a printer carriage supporting a print head for printing the jettable emulsion on a side of the pre-stretched mesh opposite the platen.

A printing screen includes a screen-shaped fabric layer with fabric threads being angled relative to one another to form a carrier layer. An imaged stencil layer is connected to the fabric layer and provided with passages. A respective passage forms a continuous channel and has an opening that is smaller on a printing material side of the printing screen than on a squeegee side of the printing screen. Such a printing screen has sufficient stability and advantageously allows the finest lines and dots to be printed. A method for imaging such a printing screen is also provided.

A rotary screen printing press includes: a screen plate; a squeegee; squeegee supporting means for supporting the squeegee; and a worm and a worm wheel. The squeegee supporting means includes: a supporting plate swingably supported and supporting the worm and the worm wheel; an eccentric sleeve configured to adjust the position of the center of swinging movement of the supporting plate; and a contact surface and a screw configured to limit the direction of the movement of the supporting plate. The eccentric sleeve and the contact surface and screw cooperate with each other to move the tip of the squeegee along the tangent line of an impression cylinder at a position at which the screen plate and the squeegee contact each other.
