Durst showcases two new UV inkjet printers and printhead technology to its flagship Rho 1000 Series at ISA

At the 2013 International Sign Association Show in Las Vegas (ISA), Durst Phototechnik unveiled the new Rho 1012 and 1030 printers, as well as Variodrop printhead technology.

Durst Rho 1000 printer series

The Rho 1000 has proven itself as the most productive wide format UV inkjet printer offered on the market, and the 1012 and 1030 further enhance its market leading position.

The Rho 1012 is the first 12 picolitre flatbed printer in its class made possible by Durst's latest Quadro Array printheads. The very small drop size provides unrivalled 1000 DPI print quality whilst maintaining exceptional productivity of up to 490 m² per hour. The Rho 1012 offers users the ability to meet the quality and volume requirements normally reserved for offset printing but with the media flexibility only possible with digital inkjet printing.

The Rho 1030 is the fastest fully automated flatbed printer available. It is capable of production speeds of up to 1000 m² per hour without compromising the quality of print. This printing speed and full automation with auto loading and unloading tables makes it ideally suited to incorporation into an industrial production line. Also available are both roll to roll and roll to sheet print options to further enhance the machines' media flexibility.

Existing Rho 1000 users will be able to upgrade their existing machines to either the Rho 1012 or the Rho 1030 in the field, further maintaining Durst commitment to providing customers with long term solutions to their printing needs.

"The introduction of the 1012 and 1030 is a natural fit for what we have been hearing from the market", explains Michael Lackner, Marketing Manager of Durst, "The Rho 1000 is a proven high volume wide format digital printer and the capabilities of the two new printers, along with the automation solutions, make this a very strong solution for many of our print partners."

Durst have also launched the innovative development of Variodrop printhead technology to its Rho P10 Series of UV inkjet printers, which further enhances the unrivalled quality of all the printers in the series.

The benefits of Variodrop are refined greyscale technology, with improved productivity and image quality whilst overcoming some of the errors which can occur with greyscale printing alone. In particular, greyscale relies very strongly on accuracy of drop placement and this can be affected by the uniformity of velocity of drops. Any variations of the printheads' working conditions could lead to a mismatch of different greyscale level drop velocities and the consequence is drop placement inaccuracy.

"There is a significant increase in productivity of up to 25% for all the Rho P10 Series printers," says Michael Lackner, Marketing Manager of Durst. "For example, with Variodrop the output of the P10 250 is up to 240 m²/h featuring an ink drop size of 15 picolitres. In addition, the quality is improved for both 15 picolitre and 10 picolitre printing, including better colour gamut and even smoother solid colours."

Variodrop is an adjustable binary mode which uses multi-pulsing for drop size modulation and is not concerned with possible drop velocity variations associated with greyscale printing. It combines two voltage pulses in such a way that the second pulse pumps precise dosage amounts of ink into the droplet before it detaches from the nozzle plate without forming any satellites. This new printing technology is a major improvement and it surpasses greyscale only applications almost every time.

The Rho P10 printers offer a DPI of 1000 and are the first industrial level UV inkjet printers featuring the very small drop size of only 10 picolitres. Thanks to Durst's latest Quadro Array printhead technology associated with the P10 Series, the exceptional quality is maintained at the highest level of productivity and Variodrop enhances the final output even further.

Both printers are available for UK customers from May 2013.
