Direct to mesh screen stencil creation
A direct to mesh (DtM) screen printer for creating a screen stencil is provided. The DtM screen printer includes a frame to hold a pre-stretched mesh in place during application of a jettable emulsion, a fixture to hold the frame, a platen to hold a release fluid against one side of the pre-stretched mesh, a fluid dispenser for dispensing the release fluid onto the platen or 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 process is also provided, the process being for using the DtM screen printer to prepare the screen stencil for screen printing.
ROTARY SCREEN PRINTING APPARATUS AND PROCESS
The present disclosure is directed to a rotary screen printing apparatus, comprising: a rotary cylindrical screen; a conduit which provides fluid communication to an internal volume of the rotary cylindrical screen; and, a heater whose output is directed towards the conduit.

Printing machine
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.

Sheet-fed printing unit configured as a screen printing unit
In some examples, a screen printing unit includes a screen printing forme cylinder, an impression cylinder, and at least one further rotational transport body. A fixing element of the impression cylinder includes inner and outer contact surfaces for clamping sheets. The inner contact surface has a base radius as a distance from an axis of rotation of the impression cylinder. A cylinder barrel of the impression cylinder has a supporting surface for sheets that includes an impression portion having a constant barrel radius, which extends over at least 170 about the axis of rotation of the impression cylinder and the barrel radius is larger than the base radius. A fixing element of the further rotational transport body includes an inner and an outer contact surface for clamping sheets. The inner contact surface includes the base radius as a distance from an axis of rotation of the further rotational transport body.
Sheet-fed printing unit configured as a screen printing unit and comprising two base modules
In some examples, a screen printing unit includes a screen printing forme cylinder, an impression cylinder, and a frame including two frame side walls. The screen printing unit further includes first and second base modules, each comprising two stationary base side walls that each have a one-piece design. Each base module includes four installation areas for rotational transport bodies whose positions coincide in the base modules, and the respective first and second installation areas of each base module form a respective selection group of the base module. An impression cylinder cooperating with the screen printing forme cylinder is in one of the installation areas of the selection group of the first base module, and a respective rotational transport body is arranged in each of the four installation areas of the base modules. A functionally different rotational transport body is arranged in an installation area of the first base module.
