Correct and careful handling are the two most important factors in
maintaining the life of a screen. Careless handling can destroy a screen's
usefulness within seconds and is a major cause of premature screen failure.
Another cause of screen failure is improper printer set-up, which leads
to bagging of mesh.
Proper tension is critical in achieving consistent, precise prints
over long production runs. A properly tensioned screen will give excellent
peel characteristics at a minimum snap-off setting (Snap off, breakaway,
or screen height are terms for the undeflected distance between the
screen and the substrate).
Minimum snap-off settings reduce screen stretch and subsequent pattern
misregistration.
Newton gauges measure deflection within a specific amount of area encompassed
within the footprint of the gauge while an interior spring applies pressure
against the mesh.
Therefore recommended Newton's per Centimetre (N/cm) readings for specific
mesh are valid for any frame size.
