摘要： A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.

摘要： Provided is a method and device for stencil printing which can readily achieve a stencil printing of a prescribed even density even when the surface area of the printing surface is great, and which can ensure a multi color printing to be made without mixing of colors even when a large number of copies are to be printed. Printing ink having a sufficient consistency to retain its shape is deposited on a stencil master plate S as ink lumps B, and a stencil master plate S is placed in a pressure chamber 17 with its surface carrying the ink lumps B facing the diaphragm 15, the pressure chamber 17 having a wall portion formed by a diaphragm 15 which is at least either flexible or elastic. The pressure chamber 17 is then depressurized so that the diaphragm 15 conforms to the ink lumps B and wraps itself onto the ink lumps B, and the stencil master plate S in turn comes into close contact with the printing paper P by being pressed by the diaphragm 15 to thereby achieve a stencil printing on a sheet of printing paper through pressurization of the ink lumps B on the stencil master plate S.

摘要： In a stencil printing including the steps of supplying ink in the form of a layer on one side of a perforated stencil sheet, contacting another side of the stencil sheet to a surface for printing, applying a pressure to the ink layer by a pressing means so as to transfer the ink of the ink layer through perforations of the stencil sheet from the one side to the other side of the stencil sheet and to attach the ink thus transferred onto the surface for printing, and detaching the surface for printing from the other side of the stencil sheet, the improvement is which the surface for printing is detached from the other side of the stencil sheet at a portion thereof where a movement of the ink layer relative to the stencil sheet is substantially impeded by the pressing means so that a drawing out of the ink from the ink layer onto the surface for printing due to the adhesiveness and viscosity of the ink does not occur when the surface for printing is detached from the stencil sheet, thus also allowing the extrusion of the ink through the stencil perforations to be expedited before the stencil sheet tightly contacts the printing surface, so as to avoid blank shadows of fibers of the stencil sheet, while avoiding the problem of back contamination.

摘要： A silkscreen printing system for multicolor printing by the application of separate colors in a predetermined order is provided in which a plurality of printing tables are positioned in the path travelled by the print material through the printer arrangement. Each of the print tables cooperates with the respective stencil which is intended to transfer to the print material a single color of the multicolor print. The system also includes a material transporting arrangement for advancing print material to a first of the plurality of print tables so that a first color is applied to the material by the stencil located above the first table. Subsequently, a second printing table receives the print material by the transport of the material transporting means so as to apply a second color print to the print material. The material transporting arrangement extends along all of the plurality of printing tables in the arrangement and is non-electrically conductive. The non-electrical conductive material permits a drying arrangment, operating by electromagnetic waves, to be placed in an area between mutually adjacent printing tables.
