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 screen printing apparatus for printing paste on a printed pattern of a print target constituted of a substrate or a plurality of aligned substrates includes a mask having a plurality of opening patterns different in size from one another. The screen printing apparatus images the substrate or one of the aligned substrates constituting the print target, and calculates a level of deformation by expansion and contraction of the print target, based on a result of the imaging. The screen printing apparatus then selects an opening pattern from among the opening patterns, based on the calculated level of deformation by expansion and contraction of the print target, brings the print target into contact with the mask to superimpose the selected opening pattern on the printed pattern, and deposits the paste on the printed pattern.

A printing method for carrying out printing with respect to various printing target objects through a more appropriate method using an inkjet head, the printing method including a screen preparing step of preparing a mesh-like screen, an ink discharging step of discharging an ink droplet from the inkjet head to one surface of the screen, a viscosity increasing step of enhancing a viscosity of the ink on the screen, an ink push-in step of pushing the ink with enhanced viscosity from the one surface side toward other surface side of the screen, the step including pushing in the ink while a medium, or a target object of printing, and the other surface of the screen are making contact to attach the ink with enhanced viscosity to the medium, and an ink fixing step of fixing the ink attached to the medium to the medium.

A method of screen printing positionally synchronizes a plurality of pallet assemblies on a first screen printing machine with a plurality of pallet assemblies on a second screen printing machine. A screen printed garment having a properly aligned first image received from the first screen printing machine is transferred on a portion of one of the pallet assemblies on the first screen printing machine to one of the plurality of pallet assemblies on the second printing machine. The properly aligned first image on the garment is in proper positional alignment with a screen printing head on the second screen printing machine such that a second image complimentary to the first image is printed on the garment in proper position on the garment relative to the first image without user intervention to positionally locate the first image relative to the screen printing head on the second machine.

A method of performing screen printing on a substrate used for the manufacture of a solar cell is provided. The method includes moving a print head over a screen by a first drive actuator to perform a printing stroke in a first direction. The method includes moving a material processing head in the first direction by a second drive actuator to perform a material processing stroke behind the print head. The print head is moved away from the material processing head by the first drive actuator during a distance increasing phase of the printing stroke to increase a separation distance between the print head and the material processing head.

The application relates to a doctoring unit for a printing apparatus for printing flat substrates, in particular circuit boards, wafers, or solar cells, comprising two doctor blades, which extend parallel to one another and are pivotably mounted. It is provided that the doctor blades are operatively connected to a gearing, which is formed in a self-locking manner and can be coupled or is coupled to a drive device.

A screen printing press includes a base and a clamping mechanism which is connected to the base. The clamping mechanism has a first member, a second member disposed perpendicular to the first member, and an edge. As screen has a first surface and a second surface perpendicular to the first surface. A protruding stop is disposed on at least one of the first surface and the second surface. The screen is positioned in the clamping mechanism so that the first surface abuts the first member, the second surface abuts the second member, and the protruding stop abuts the edge. The base includes an open frame which defines a volume which is shaped and dimensioned to receive a burn unit, so that when the burn unit is placed within the volume the burn unit is visible.

A manufacturing system for applying a material to a workpiece comprising a blade unit having a blade element for selectively moving along first and second axes for applying the material to the workpiece. A reciprocating motor is coupled to the blade unit for reciprocating the blade element along the first axis concurrent with movement of the blade element along the second axis, and a vibration detector is coupled to the blade unit for detecting the vibrational movement of the blade element. The vibration detector generates an output signal corresponding to the vibrational movement of the blade element. A control unit is coupled to the vibration detector for generating an output signal in response to the vibration detector signal, and a regulating device adjusts a parameter of the reciprocating motor in response to the output signal of the control unit.

A method of screen printing positionally synchronizes a plurality of pallet assemblies on a first screen printing machine with a plurality of pallet assemblies on a second screen printing machine. A screen printed garment having a properly aligned first image received from the first screen printing machine is transferred on a portion of one of the pallet assemblies on the first screen printing machine to one of the plurality of pallet assemblies on the second printing machine. The properly aligned first image on the garment is in proper positional alignment with a screen printing head on the second screen printing machine such that a second image complimentary to the first image is printed on the garment in proper position on the garment relative to the first image without user intervention to positionally locate the first image relative to the screen printing head on the second machine.

A printing stencil (1) for forming conductor tracks on a substrate. The printing stencil (1) has a plurality of cutouts in the form of printing gaps (4) for forming the conductor tracks. Each printing gap (4) of the plurality of printing gaps (4) has at least one print definition region (3) adjacent to the printing side and at least one printing medium supply region (2) adjacent to the squeegee side, the volume of the print definition region (3) being smaller than the volume of the printing medium supply region. Moreover, a printing device for forming conductor tracks on a substrate and a method for producing a metallic contact structure of a photovoltaic solar cell are also provided.
