Abstract
A print head for silk-screen printing apparatus is provided. The silk-screen frame and squeegee of the print head are fixedly connected together to provide that the two move together in rotational manner. Thus, the squeegee can be made to always print across the square-shaped mesh of the woven screen rather than across diamond-shaped mesh whereby to eliminate or at least minimize or localize moire. The silk-screen frame and squeegee can be rotated together to a predetermined angle or degree, in advance of the printing of a particular color in the silk-screen printing of halftones.
