Get ready for the Rho

 

Already considered to be the most productive 12-picolitre inkjet in its class, the Rho 1012 prints with a resolution of 1000 DPI at speeds up to 490m². Now, with the addition of Durst’s own Variodrop technology, enhancements to the image quality mean that it is capable of delivering excellent results at even faster printing modes.

The Rho 1012 features Variodrop technology, which ensures that solid areas are even smoother, while it also helps to overcome some of the errors that 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.

The Variodrop on the Rho 1012 changes the drop size from 12 to 20 picolitres and, even at the larger drop size, solid colours are smoother and have an improved colour gamut. Variodrop is an adjustable binary mode that uses multipulsing for drop size modulation. It combines two voltage pulses in such a way that the second pulse pumps the precise ink dosage into the droplet before it detaches from the nozzle plate, without forming any satellites. Compared to the often uneven droplets formed from an ill-tuned greyscale waveform, with Variodrop the double pulse drop shape is perfectly uniform and its placement is always evenly spaced.

In common with other Durst inkjet printers, the Rho 1012 is upgradable in the field, which means that the new Variodrop technology can be added to existing customers’ printers.

The Rho 1012 has a host of features such as left and right registration, which enables parallel printing of boards side by side and mechanical two point pin registration for perfect front and reverse side printing. Printing options include fast media change from rigid to roll and options for roll to sheet or roll-to-roll printing, plus ink options that include light colours and Process Colour Addition (PCA).
