Surveying your UV machine options.
Durst Rho 700, 320R UV, Rhopac 160: Durst's (durstus.com) Rho 700 is designed to bridge the gap between the company's Rho 600 Pictor and the high-performance Rho 800. The 700 is a modular machine that can be upgraded and configured in a variety of ways for different applications. All permeations of the machine feature Durst’s 600-dpi Quadro Array print heads, a maximum print width of 80 in., and a new magnetic linear drive system for the print carriage. The Basic model prints in CMYK at speeds up to 540 sq ft/hr, while the Presto doubles the number of Quadro arrays from four to eight and enables maximum throughput of 1075 sq ft/hr. A roll-to-roll option allows the machine to function as a hybrid printer; a heavy-duty roll option is also offered. Other options include expanded color scheme (adding Lc and Lm), white printing, clear varnishes, spot colors, corrugated board printing, and an industrial version designed for heavier and/or thicker media (up to 2.75-in. thick).
The Rho 320R is an industrial rollfed UV printer that features the company’s Quadro Array printhead technology, a print-carriage concept based on a magnetic linear drive system, and low-odor, VOC-free Rho Roll inks. The 4-color (CMYK) Rho 320R prints widths up to 10.5 ft on a range of coated and uncoated media up to 1400 sq ft/hr, with a maximum resolution of 600 dpi. White printing and light-color options are available. The machine can accommodate a wide range of media up to 2-mm thick. Users can opt to print two rolls side-by-side up to 62-in. each, and take advantage of a media-tracking feature that allows for registered doubled-sided printing.
For the Rho 320R, Durst has developed specific, virtually odorless UV-curing acrylic inks that afford quick curing, high adhesion even on uncoated surfaces, and high flexibility. Other features include: an external Caldera RIP server with GrandRIP+ software; a transport mechanism featuring a roll support at the loading side allowing the use of pneumatic 3-in. or optional 6-in. core axles with an outside diameter of up to 17.7 in.; and enhanced user software.
