Frequently asked questions — Sealed ink cup 70mm pad printing

What is a sealed ink cup and why is it better than an open ink trough?

A sealed (hermetic) ink cup is a closed system where ink is contained in an aluminium cup sealed against the cliché by a ceramic ring. Unlike open ink troughs, sealed cups prevent ink evaporation, reduce solvent loss, and require less frequent ink replenishment — making them cleaner, more economical, and better suited for production environments.

Is this ink cup compatible with the Keygadgets K-1 pad printing machine?

Yes. The 70mm sealed ink cup is specifically designed for the K-1 pad printing machine. The magnetic pressure system and ceramic ring dimensions are matched to the K-1 inking unit for optimal performance.

Can I use both solvent-based and UV inks with this cup?

Yes. The aluminium body and ceramic ring are compatible with both solvent-based and UV-curable pad printing inks. Always clean the cup thoroughly when switching between ink types.

How do I clean the sealed ink cup?

The cup is designed for quick disassembly without tools. Remove the ceramic ring, pour out remaining ink, rinse with the appropriate solvent for your ink type, wipe clean, and reassemble. Regular cleaning after each production run extends the life of both the cup and the ceramic ring.

When should I replace the ceramic ring in the ink cup?

Replace or re-lap the ceramic ring when you notice ink streaks on the cliché after doctoring, ink leakage around the cup base, or inconsistent ink transfer. The ceramic ring is available separately — see our 70mm ceramic ring listing.
