Durst Image Technology
Capable of operating in a continuous-feed workflow to eliminate load/unload delays between sheets, the Rho 1000 can print on sheets, heavy boards, and roll media, and can accommodate substrates up to 8-ft wide and 1.58-in. thick (2.75-in. thick in the “industrial version”). It can hit speeds of up to 5400 sq ft/hr (4100 sq ft/hr in the Rho 1000L version) and offers a top resolution of 600 dpi. Four colors (CMYK) are standard, with options including light cyan, light magenta, white, clear varnish (gloss), and process color additions (orange and green or orange and violet). Rho Premium Rigid Inks and Rho P-O-P Inks are available. Durst recently added a Smart Speed Option (accelerates print speed by more than 20%) and a Spot Gloss Option; a Mirus feeder allows for the loading of stacks up to 1500 kg on pallets from three sides (and two parallel stacks can be loaded at the same time). The feeder is capable of handing media up to 5-mm thick. A Mirus stacking solution is also available.

The Durst Rho 900 UV printer, based on the company’s 800HS model, features an automated media handling (auto-feed) system and process colors – orange and green, or orange and violet. The 98-in.-wide Rho 900 is equipped with Durst’s Quadro 30D Array printhead technology and offers 600-dpi resolution. Durst reports that the 8-color machine (CMYK + 4 ink bays that can be set up as print jobs/apps required) can hit a maximum output of 72 4 x 8-ft boards/hr with its continuous board printing option; speed for P-O-P-quality printing is 34 4 x 8-ft boards/hr. It can accommodate media up to 1.58-in. thick (2.75 in. in the industrial version) and as small as 12 x 17 in. if need be. The media-handling system incorporates an auto-feed table with belts, sheet feed gate with guides for parallel board printing, and automatic two-point pin registration system to ensure accurate front-to-back registration.

Other Durst UV models include the Rho 1000L, Rho 800 Presto and Presto /HS, Rho 750 HS, Rhopac 160 Corrugated Display Printer, Rho 500R and 320R.
