Pad Printer Magnetic Sealed Ink Cup

A sealed inkcup system is essentially and inverted inkcup that is filled with ink and uses the sharp rim of the cup as a printing plate wiping system. As this system floods and doctors (wipes) a printing plate in the same motion, solvent evaporation and ink viscosity changes are much more limited than with doctor blade systems, making the sealed inkcup printing process significantly more predictable and manageable.

Nearly all sealed inkcup types can be broken into two categories, magnetic or non-magnetic. Both inkcup types, when integrated into the pad printing machine yield excellent results for clean, properly doctored printing plates.

Amagnetic inkcupis basically “self-doctoring unit”. With its extremely powerful magnets, it has all the necessary down-force to clean the plate requiring the pad printing machine to simply pull it back and forth. The magnetic inkcup generally has found its strength in multi-color applications because the pad printing equipment can generally be of simple construction and the multi-color pad printer more cost effective.

Non-magnetic inkcupsare designed to have the pressure applied by the pad printing machine to an outer flange or centering hole in the cup. The pressure is applied by a spring-loaded system geared for one inkcup assembly. The spring-loaded system is compact and very effective, but is not as simple to deploy on a multi-color pad printing machines. The non-magnetic inkcups seem to have their niche in compact or high speed machine applications. In these systems, even at high speeds, the spring loaded hold-down system keeps the inkcup firmly in place while the plate moves in and out.
