Printheads that are durable, not disposable

The EJ-640 DECO features precision printheads that are designed for high-output operation year after year – not just for a few litres of ink. Without the constant replacement of printheads as required with other similar systems on the market, you can enjoy true colour consistency on long print runs and repeat work, plus minimal downtime.

The EJ-640 DECO also has a three-part patent-pending wiper system designed to significantly reduce ink build-up around the edges of the printhead, decreasing wear and tear and prolonging its life even further.

Boost your versatility with no-cure, low-temperature printing

Unlike other printers, the EJ-640 DECO uses a low-temperature drying process that maintains the production on many materials.
