PURPOSE:To automate face-back inversion and directional changes of a sheet as an object work to be printed by providing a position setting table for matching the position of the sheet to the position of a printing plate according to a signal from a position recognition device. CONSTITUTION:A screen 71 of s printing plate for printing is set on a plate- holding part 2 by a horizontally moving operation 20. A dummy sheet is fed onto an X.Y.theta table 3 positioned on the lower side of a position recognition device 4, by a rotational feeding operation 21 of a dummy sheet-feeding part 5. The table 3 with the dummy sheet mounted thereon performs a horizontally moving operation 22, whereby the table 3 is positioned on the lower side of a printing head part 1 and the plate-holding part 2. The printing head part 1 performs a printing operation 23 with a movement of a squeegee. When the printing operation 23 for the dummy sheet is finished, the table 3 is returned through a horizontally moving operation 22 reverse to the above, and is positioned under the position recognition device 4. The position of a mark on the dummy sheet thus printed is read by a recognition camera, and the position is stored. Printing on a formal sheet is conducted by taking a sheet frame with the sheet adhered thereto, out of a magazine. |
