The Rho 1000 is the flagship of Durst`s comprehensive range of flatbed and roll to roll UV inkjet printers. It is ideally suited for integration into existing production systems and is capable of achieving a production output of up to 500 boards per hour (125 x 80 cm), without interruption, around the clock, whilst ensuring optimum quality.

Rho 1000 Key features

Overall advantages of the Rho 1000

The Rho 1000 continuous inkjet production system is the most flexible and productive system in the market:

• Automated continuous printing of boards and sheets
• Highest material flexibility (boards, sheets, roll media)
• Highest flexibility of sheet sizes (250cm width by any length)
• Fast media change enables the printing of a whole campaign using different media in one operation

Media transportation features

Auto loading table  

Vacuum belts advance the media whilst side guides guarantee precise media advancement in y-direction. Mechanical 2 point pin registration ensures exact media registration in the print direction and the left and right registration of media provides precise front to back registration, enabling parallel printing of up to 4 boards

Precise registration of media

For automated printing, accurate registration of media is essential. The registration accuracy of the Rho 1000 is +/- 0,5 mm. When printing a stack of media, this accurate registration means that the printed boards are ready for immediate guillotining. Precise front to back registration is achieved by right and left registration as boards and sheets are always registered at the same edges.

There is a gate for automatic printing of boards >3 mm thickness and the pull bottom sheet feed enables loading of media during printing. Media side guidance allows for parallel printing up to 4 sheets and there is front and back pin registration for 3⁄4 automatic printing.

Auto unloading table

Vacuum belts advance the media and a tray or stacker takes up the sheets. Printing from stack to stack and directly loaded onto a pallet completes the automated process.

Vacuum belt transport system

The vacuum belt transport system has an encoder controlled step motor and the vacuum strength is user controlled, providing precise transportation of different board and sheet material. The strong vacuum is only applied directly below the printing area and there are 12 independent and computer controlled vacuum zones which ensure efficient media transport without the need for masking.

Four media handling modes

Full automation 

Up to 4 parallel boards are loaded onto the auto feeding table in stacks Mechanical 2 point pin registration ensures exact media registration and the right and left registration of boards ensures highest precision for reverse printing. Continuous printing optimises productivity and to complete the automated process, the unloading table transports the media to the auto stacker.

Three quarter automation

Single sheets are loaded onto the table

Then the same features as full automation apply: mechanical 2 point pin registration, right and left registration of boards for reverse printing, continuous printing for optimised productivity and the unloading table transports the media to the auto stacker.

Manual

Manual loading and unloading
For special applications such as printing very long panels, manual loading and unloading of single boards or sheets is very easily handled.

Roll to roll printing

Continuous printing onto roll media provides total media flexibility
The Rho 1000 allows for a fast change from rigid roll media. Heavy rolls are loaded onto the roll media device and dancer rolls ensure precise tensioning of the media. The roll can be re-adjusted during printing and the printed roll is precision wound

Variable Data Printing (VDP)

Durst Quadro Array printhead technology 

The Rho 1000 has the latest Durst Quadro Array 30M printheads, which have 1024 nozzles per array, providing over 65,000 inkjet nozzles in total, for high productivity with uncompromised quality. The drop straightness, with a deviation of only 1.5μ, provides an even higher image quality. The nozzle plate is now constructed using silicon oxide MEMS production technology with anisotropic etching for greater robustness and accuracy.

Rho 1000 Ink Options

Rho ink colour options

Different ink options are offered on the Rho 1000 and these include: special light colours, light magenta and light cyan, for even finer colour graduations and perfect skin tones. Durst`s pioneering white ink printing is also available and its special effect varnish.
In addition, there is the further option of Process Colour Addition (PCA). The two process colour options, either orange and green or orange and violet, extend the colour gamut and provide perfect rendition of even difficult corporate colours.
