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.

Advantages

• Addressable resolution 400 x 400, 400 x 600 dpi at your choice, in 6 passes according to the needs of quality and productivity
• CMYK Rho Roll Inks and 2 spot colours (white over/underprint, functional varnish, orange, green and ocean blue. UV curable inks allows for immediate use of printed material
• Low ink consumption achieved by high pigmented inks providing low ink cost/m²
• Environmentally friendly ("green technology"), no VOC`s
• Easy and fast media change with max. 70 cm media waste/change
• Virtually odourless, high density inks with high flexibility, no wicking on fabrics, and high colour retention from the use of pigments with an 8 classification on the Blue Wool Scale
• Unattended printing of big rolls is provided due to the built in security system (GSM modul with error warning via mobile phone - optional)
• Simultaneous printing on 2 rolls (each 1600 mm/excluded fabrics) even of different diameter
• User-friendly operating software with management functions (ink usage/job, total ink consumption, print-time/job etc) and interface to external order check software
• Double sided printing with optical-based registration (single rolls)
• Highly productive workflow from simultaneous ripping/transfer and printing of files through additional RIP workstation
• Integrated manual cutting device
• Industrial standard LINUX operating software

 

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:

• Media channel, archiving for the selected tension for each media the selected, UV lamp step, pass, tension selection, vacuum strengths, and "tuning option" to compensate temperature related media characteristics
• Skip white function (passes over unprinted areas in XY direction)
• Queue function with selection criteria
• Backlit function in order to print double ink layer in one printing process
• Interface to external order management
• Efficient workflow with color management based on external Caldera RIP Server
• Automated workflow using RIP-Job- tickets and hot folders with saved speed-passes, color management and simultaneous administration of queue and hot folders.

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
