Delivering Enhanced Printing and Productivity Performance for Single Pass Printing and Heavy Pigment Loaded Inks

Ricoh Europe, London – Ricoh today announced the launch of two new Industrial Inkjet Printheads: the RICOH MH5421F and the RICOH MH5421MF. Ricoh will start taking orders for both of these printheads from June 2017.

The RICOH MH5421MF and RICOH MH5421F printheads were designed for both low viscosity (6 mPas) and medium viscosity fluids (11 mPas) respectively. These printheads enable highly stable jetting performance through the incorporation of an ink recirculating structure. This structure enables continuous ink flow directly behind the nozzle, reducing the risk of jetting failure caused by either clogged ink or entrapped air bubbles. Each printhead has enhanced bonding technology for improved durability. With these new features, the Ricoh MH5421 MF and MH5421F printheads offer enhanced compatibility with a wider range of fluids. These features result in:

• Increased reliability for single-pass printing by delivering improved print quality and productivity

• Increased reliability for systems with rapid setting ink, such as pigment ink, white or metallic materials

• Increased reliability for systems with fast drying ink

• The removal of air bubbles in the ink chamber to achieve self-recovery from jetting failure

?Single-pass system?the printhead carriage remains in a fixed position and completes image printing in a single pass while the print material is conveyed underneath.

?mPa?s?Unit of viscosity (millipascal-second) Higher numbers mean higher viscosity

In the Industrial printing market for textiles, labels, packaging and ceramics tiles, there is an increasing need to meet a wide variety of customer needs such as smaller lot sizes and shorter delivery times. This requires the rapid digitisation of industrial printing in order to deliver greater flexibility and productivity, resulting in increased demand for printheads that deliver finer image quality as well as high productivity and greater reliability. RICOH MH5421 F and RICOH MH5421MF offer high resolution printing to support its industrial partners and customers to meet these market needs.

Ricoh will introduce RICOH MH5421F and RICOH MH5421MF as well as other Industrial Printing solutions at InPrint which is the exhibition for industrial print technology, taking place from 25-27 April 2017 in Orlando, Florida.
