42 Technology delivers ink delivery breakthrough for Xaar


27-08-2009

Product design and development consultancy 42 Technology (42T) has helped develop an innovative ink delivery system for Xaar that will enable manufacturers to bring next generation, high speed, commercial digital printing technology to market – faster and at lower cost.

The Hydra recirculating ink supply system [shown here] has been designed to make it much easier to develop prototype printing systems, based on Xaar’s award-winning 1001 printhead, by removing one of the most time consuming, costly stages in the development process.  In the past, manufacturers have had to spend time matching their proprietary inks, delivery system and the intended printable surface with the head.  Whereas they can now buy an ‘off the shelf’ unit that supports a wide range of fluid types, viscosities and operating temperatures as well as different printhead orientations.

42T and Xaar developed the initial concept and architecture for a new pumped ink delivery system which was then further optimised by Xaar’s in-house team of product engineers.  The resulting compact small footprint unit was launched earlier this year to further strengthen the company’s position in the fast-growing commercial inkjet printing market.  Xaar has already shipped almost 50 Hydra units in the first three months of sales and is experiencing a huge increase in demand for its 1001 printheads.

“42 Technology has not only helped develop a market-winning system to boost sales of Xaar’s 1001 heads but has also optimised our product development strategies.  The consultancy’s engineering team took a fresh look at our new product development process and, utilising their own in-depth experience across a variety of markets, worked with our in-house team to introduce some significant improvements.  Hydra, which is already a sales success, is the first of a number of breakthrough products that we expect to deliver from this improved approach,” said Dr Brian Rafferty, engineering manager at Xaar.

42T’s project managers and engineers worked as an integral part of Xaar’s in-house resource.  A detailed product specification was agreed, concepts were developed and investigated using advanced hydraulic modelling techniques before sub-systems were designed and tested.  Only once a thorough understanding had been established was a detailed system designed and developed.

Hydra delivers ink on demand to four Xaar 1001 printheads, is easy to operate with just three buttons and can very accurately maintain the ink’s operating parameters (pressure, temperature, viscosity and flow) across the head.  Accurate control is essential in delivering high quality print and an easy to use system.  Hydra is also scalable allowing manufacturers to rapidly develop large format, 1001-enabled printing technologies by using multiple units side by side; the units are designed to handle a full range of fluid types including high viscosity and heavily pigmented inks.

Xaar’s 1001 printhead is ideal for high speed, single pass, commercial print and packaging and is central to a number of innovative inkjet presses.  The head was awarded the PIA/GATF Intertech Technology Award in 2008 when the judges commented that it was ‘a truly innovative design of inkjet head technology’ that would offer ‘faster speeds, improved productivity and increased resolution’.
