In a gravure plate for wiring printing on which a recessed portion defining a wiring pattern is formed on a plate surface, a projecting portion for reducing a volume of the recessed portion is formed on a bottom surface of the recessed portion. A contour of the projecting portion in cross section parallel to the plate surface has a semicircular arc shape, which protrudes toward one side in one direction that is parallel to the plate surface, on the one side. The recessed portion has a side wall that is composed of a plane orthogonal to the plate surface and faces the projecting portion at a distance of 15 m or less without coming into contact with the projecting portion. The contour of the projecting portion has a semicircular arc shape, which protrudes toward the side wall, also on a side closer to the side wall.

The present invention discloses a four-position full-cell solar silicon wafer printer, including a base, an infeed guide rail, a detection camera assembly, a turntable assembly, a lifting module, a UVW correction alignment mechanism, and an outfeed guide rail. The UVW mechanism comprises two Y-axis modules, one X-axis module, a printing platform, a steel mesh frame, and a printing squeegee kit. The Y/X-axis modules are under the platform, their drive ends connected to the steel mesh frame. The squeegee kit moves left-right on the platform. It uses the Y/X-axis modules and detection camera to realize X, Y, three-axis motion, ensuring steel mesh-silicon wafer alignment and optimizing printing directions.
