Static Problems
with Gravure Printing
High speed gravure printing on plastic films results in high amounts
of static that can ignite solvent vapors. As the web exits the printing
rollers there is often a generation of high static charge resulting
from the pressure and speed.
Solution
Place Static String™ very close to the rollers at a point where
the web is not in contact with the machine. Static String can be placed
anywhere from direct contact, to up to a few inches away from the
web but must be in a gap where the web is not touching the machine.
String may be placed on either side of a thin web.
To determine the optimal placement, use a static meter to measure
the static charge levels. You do not need to reduce the static charge
to zero or even near zero. To prevent ignition, keep the charge below
5KV. To prevent shocks, keep the charge below 10KV. To eliminate dust
attraction, keep the charge below 3KV.

Recommendations
Static Elastic™ and ion360F™ Ionizing Rods may also be
used.
