What’s the difference between a single-axis squeegee blade and a bi-axial squeegee blade?


Traditional squeegee blades of all types are single-axis—they are made to conform in the stroke direction only. As the blade starts printing, it flexes more nearest the frame, least at the center of the screen and most again at the end of the stroke. However, it is insensitive to the resistance differential side-to-side, which is why screens rip at the edges.

A bi-axial squeegee blade is sensitive to the resistance differential in both the stroke and perpendicular axes (directions) of the screen. This design allows minimum angle, minimum pressure and maximum speed, so the blade meters consistent amounts of ink at all points on the screen.
