90mm Kent inner cups, packet of 50. These ink cup liners are designed to be used with the Kent Green Ink Cup and can be used with either the ceramic or steel (tungsten) ink cup ring. There are many advantages to using KENT’s patented Green ink cup system including: • Not having to clean ink cups with solvents, simply remove the ink cup liner. • Excellent for use with ink-hardener mixes. • The green ink cup minimises ink and additive consumption as evaporation is greatly reduced. • Improvement in productivity due to very little clean up time. • No need for spare ink cups (for non-stop production) as inks can be mixed directly in the liners and placed straight in to the ink cup. • Ink (not mixed with hardener) can bestored directly in the inner cup for later use. Lids for the inner cups are available.
