ABSTRACT:
The invention is directed to a method of printing a pattern on a substrate, the liquid retained within the printing screen is in a first position directly above the point of tangency between the screen and substrate so that a lesser quantity of liquid is deposited to provide raised beads of liquid comparable in size to the size of the apertures of the screen.
The reservoir of liquid is shifted away from the point of tangency and therefore a larger quantity of liquid passes through the apertures because the apertures are now spaced from the substrate. The larger quantities of liquid flow together and therefore, a pattern is provided larger than the aperture size of the screen.
