ABSTRACT:
A screen setting apparatus accurately locks a screen in position so that reference marks of the screen come directly in line with reference marks of a printing table, which table secures a sheet material to be printed. The apparatus comprises three registration devices, a screen having reference marks thereon, a screen fixing device, and a printing table securing a sheet material to be printed and having reference marks. The three registration devices are a first registration device, the reference mark of the printing table corresponding to a fixed relationship of the second registration device (i.e., a reticle) and a third registration device. The reticle is lined up with the reference mark of the screen and then the screen is locked in opposition by connecting the screen fixing device with the first registration device.
