The present invention relates to a manufacturing method for a bent plate with a printed layer including: holding the bent plate by bringing a second main surface of the bent plate into contact with a surface of a fixing jig in which the surface of the fixing jig has a shape corresponding to the second main surface; disposing a screen having a printing pattern portion above the bent plate; bringing a squeegee into contact with a printing start part of the bent plate via the screen; and causing the squeegee to relatively traverse the bent plate along the first main surface via the screen, in which an angle on a moving direction side of the squeegee is changed when the squeegee is caused to relatively traverse the bent plate.

A screen printing device is disclosed for printing in a label area. An example screen printing device includes a printing pallet having a chest image printing surface connected to a label printing surface. The label printing surface extends outside of a chest image printing area of a printing machine when the screen printing pallet is loaded onto the printing machine. An example screen printing device includes an offset squeegee configured for a printing operation by the printing machine on the label printing surface.

Disclosed herein are apparatuses for screen printing on a surface of a three-dimensional substrate comprising a substantially rigid, substantially planar frame having a perimeter defining a region within the perimeter having a given surface area; and a screen attached to the frame and extending across at least a portion of the surface area, wherein the screen comprises a first portion through which a liquid printing medium can pass onto a proximate three-dimensional substrate; and a second portion coated with an emulsion substantially preventing the liquid printing medium from passing through the second portion of the screen, wherein the screen has a fixed tension of less than about 20 N/cm. Methods and systems for screen printing on a surface of a three-dimensional substrate are also disclosed herein.

Disclosed herein are squeegee apparatuses and methods and systems for screen printing on a surface of a substrate comprising the disclosed squeegee apparatus and a framed screen. Also disclosed herein are methods for screen printing a 3D substrate comprising creating a 2D test framed screen. Methods for predicting the distortion of an image printed on a 3D substrate are also disclosed herein.

A piston having a piston crown with a combustion chamber, and a circumferential ring belt extending from the piston crown and having a plurality of ring grooves separated by piston lands. At least one of the piston lands, ring grooves or top surface of the crown is provided with a coating comprising hexagonal boron nitride. The coating can be made solely of hexagonal boron nitride, or can additionally include a resin. The coating can be a single layer coating or a multiple layer coating.

A screen printing device has a screen printing stencil. At least two doctor blade systems, each acting on the screen printing stencil are provided. The at least two doctor blade systems are arranged to each apply printing ink to an object to be printed in the same printing process. Each of the doctor blade systems has at least one doctor blade. Each of the doctor blades is arranged to sweep over the screen printing stencil. Each of the doctor blade systems is individually controlled by a control unit. The at least one doctor blade of each of the doctor blade systems is moved by a robot. At least respective two-dimensional motion paths of the doctor blades of each doctor blade system are each freely programmed and are established by control of the robot.

The label printing surface extends outside of a chest image printing area of a printing machine when the screen printing pallet is loaded onto the printing machine. An example screen printing device includes an offset squeegee configured for a printing operation by the printing machine on the label printing surface.

A X-ray film packaging bag printer is disclosed. A positioning detection device is arranged above a conveyor belt, positioning holes in an X-ray film packaging bag strip are detected by the positioning detection device, and positioning can be performed by only using adjacent two positioning holes. According to the X-ray film packaging bag printer, the accuracy of the positioning detection device can be improved, the parameter conflict with a set length of a machine can be avoided, that is, the problem of shutdown or hop printing caused by a detection error are effectively avoided; the printing stability and reliability of the X-ray film packaging bag printer are improved; the structure is simple; a printing process is integrated; the automation efficiency is high; the manual operation is reduced; the production efficiency is greatly improved; the production cost is low; the user experience is improved.

A garment printing machine is provided with a transportable platen that can be utilized to significantly decrease the delay in printing expended in loading and unloading a garment for printing in either a digitized garment printing machine or a screen garment printing machine. The platen is provided with structure that holds a print receiving area of a garment firmly in position atop a print panel support plate that forms a part of the platen. Furthermore, the invention includes a platen support structure that cooperates with the conventional couplings on existing conventional garment printing machines. A plurality of transportable platens constructed according to the invention are utilized interchangeably so that while one garment loaded on one of the platens is being printed upon in the printing machine, the prior garment just printed upon is unloaded and the next garment to be printed is loaded onto another identical platen. This totally avoids any delay in printing due to loading and unloading of garments on the platens.

A method and apparatus for screen printing facilitate the application of colors, patterns, and other indicia onto a curved printing substrate, such as a concave glass surface of an appliance. The apparatus includes a print head assembly that is typically supported by a frame and is movable relative to the frame and the printing substrate. The print head assembly includes biasing elements with movable end portions that support a wiper and apply varying levels of pressure to the wiper as it is moved along the curved surface or surfaces of the substrate during a printing process. The print head assembly and associated screen printing equipment may be automated or computer controlled so as to independently vary the pressure of the biasing elements and, thus, the pressure of different areas of the wiper along the substrate, to accommodate simple or complex curves in the substrate surface.
