I’ve heard screen printers refer to the “sweet spot” in a screen. What does that mean?

Answer

The “sweet spot” of the screen refers to the gap between the mesh and the platen (also known as off-contact distance). As the blade depresses the mesh to overcome the gap in order to print, the resistance of the mesh is highest at the edges and lowest in the center. There is a small area nearest the center of the screen where there is no difference in resistance; this is the sweet-spot.
