The Rho 351R, a further development of the Rho 350R, is a high-speed UV inkjet printer for roll media, including: paper, fabrics, vinyl and PVC films, up to a width of 3500 mm (11.6 ft). The high print quality, featuring fine text (as small as 4 point) and solid areas of colour with high colour gamut and density, is achieved using Durst Quadro Array print head technology, innovative European mecha- nical engineering and Durst`s proprietary image software. The Rho 351R uses Durst Rho Roll Ink, a virtually odourless, high pigmentation ink, which has been specially developed for excellent flexibility, adhesion and colour stability on flexible material. It is ideal for printing on such material as soft banners (fabrics) and backlit textiles, tents and awnings, truck side curtains, POP/POS signs, large format posters, building wrapping, wall paper and PVC films for backlighting, etc...
The high colour density of 2.25 D and the ability to underprint white or use it as a spot colour, enables both the printing of coloured media and the production of photo-quality backlits. The printing of backlits is automated by the special backlit function which applies double the ink coverage in one printing operation. The high productivity, up to 170 m2/hr on mesh, for example, is further optimised by the ability to print two 1600 mm wide, different diameter rolls simultane- ously, thus utilising the full width of the equipment. Productivity is enhanced still further by the stepless skip-white func- tion in an XY direction. The printing operation is enhanced by an integrated manual cutting device and the user friendly, industry standard LINUX operating software. The built-in security system allows for unattended printing of large rolls and double sided printing is made possible thanks to the laser driven registration.
The Rho 351R uses Durst Quadro Array print head technology with 512 nozzles compactly arranged in an Array and con- tinuous flowing, temperature controlled ink. Coupled with Durst`s proprietary firing impulse software, which controls the precise setting of ink drops at high frequency, ensure the printing of fine text (as small as 4 point) even on polyester fabrics without wicking, as well as strong solid colours and step-free color shades. Brush-stretch rollers and a tension regu- lation device transport even thin fabrics precisely and crease-free through the printing equipment. The UV lamps, with dichroitic coated reflectors, are adjustable in steps and cure the UV inks even on temperature-sensitive media.
The touch-screen user software is based on printing experience and is driven by industrial standard LINUX operation software and ensures reliable, 24/7 production.
The software functions include:
Durst has developed for the Rho 351R a specific, virtually odourless UV curing acrylic ink which guarantees quick curing, high adhesion, even on uncoated surfaces and high flexibility. The high pigmenta- tion of the ink provided high colour density with wide colour gamut. The output is immediately usable after printing without any post-treatment. The high flexibility of the ink ensures that uncoated fabrics can be printed without wicking and UV pre-coated fabrics show no white breaks. Thanks to the properties of the Rho Roll inks flame-proof material retain their properties also after printing.
A special mechanical and electronic device (optional) allows the simultaneous printing on 2 rolls, each 1600 mm width, even of different diameter
The integrated manual cutting device secures operation-friendly cross cutting
