US Patent 9150041 Multi-stroke screen printing method and apparatus

A screen printing apparatus is described. The apparatus has a plurality of radial arms each having a printing head associated therewith. A target area is in alignment with at least one of the printing heads wherein a design is applied to a target article at the target area by the printing head. A means for providing relative movement between the target area and the printing head provides multiple passes between a squeegee associated with the printing head and the target area. A means for providing a pressure between the squeegee and the target area is regulated such that a first pressure between the squeegee and the target area on a first stroke is not equal to a second pressure between the squeegee and the target area on a subsequent second stroke.
