TRESU Group will be presenting comprehensive ancillary solutions for automatically regulating ink supply on flexo presses at Fachpack 2018, 25-27 September, Messe Nürnberg, Nuremberg, Germany (Hall 8, Stand 8-304). At the stand there will also be information about its Flexo Innovator printing line for high-speed paperboard applications and coating systems for digital folding carton lines.
TRESU’s ancillary solutions, comprising chamber doctor blades and ink supply systems, provide enclosed, automatically controlled ink and coating circulation, resulting in clean print, uniform ink density, reductions in material waste and makeready times, and faster production speeds.
TRESU’s chamber doctor blade systems maximise print quality, efficient ink use, and savings on waste. Central to the performance of TRESU’s chamber doctor blade systems is the company’s unique “Pressure Control Technology”, which prevents the occurrence of microfoaming to ensure clean, uniform print on the substrate – even for high-viscosity metallic coatings. A key feature of the technology is a long-life rubber seal system that provides an airtight enclosure, preventing leakage and enabling ink pressure to be maintained at consistently high levels. A liquid barrier forms between the rotating anilox cells and the chamber, preventing air from entering in the cells and transferring during production. The chamber doctor blades also feature fast, safe blade exchange as standard.
The chamber programme includes lightweight, corrosion-resistant carbon fibre and ceramic variants. Systems are available for web widths from 185mm to 6000mm, and offer time and ink-saving features. They are designed for label, flexible packaging and paperboard printing and coating applications.
MaxiPrint Concept for mid and wide-web applications
For web widths from 1600mm to 6000mm, the new MaxiPrint Concept chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism for fast, efficient, automatic cleaning of the chamber and the anilox roll after production. A low-pressure shot mechanism ensures minimal water loss during cleaning. The TRESU P-Line pneumatic clamping system ensures fast, safe blade exchange within two minutes.
Narrow-web SAVEink chamber
The new SAVEink chamber, for narrow web applications, and FlexiPrint Easy chambers, for flexible packaging, feature a lightweight carbon fibre ink-repellent surface with high corrosion resistance. The SAVEink chamber is light for fast and frequent job or ink changes and features a pre-set doctor blade for precise application control for press widths up to 800mm.The sealed chamber easily locks into place so there is no risk of spilling or ink contamination.
The F10 iCon for automatic ink supply
The F10 iCon ink supply system regulates ink flow, pressure and viscosity, to ensure a constant, accurate ink density on the printed substrate, without any air contamination. This energy-efficient system also provides thorough automatic cleaning, achieving a complete ink change cycle in between five and 15 minutes. As part of the automatic cleaning, a very large proportion of the unused ink can be returned to the bucket. The F10 iCon system can be specified for the Flexo Innovator, or retrofitted on line, stack and even large CI presses. Information on TRESU’s full range of coating circulators and conditioners for high-viscosity coatings will also be available on the stand.
Setting new standards – the Flexo Innovator
On its stand will be information, animations and samples that demonstrate the TRESU Flexo Innovator inline press for advanced, high-quality, high-speed packaging production with folding carton board, paper, laminates and metallic substrates.
Custom-configured in web widths from 670mm to 1700mm, the Flexo Innovator is able to integrate water-based, solvent and UV-curable inks. It can include a host of value-adding complementary processes, including double-sided printing, gravure coating (double-sided), inkjet, cold foil lamination and converting. Speeds of up to 800m/minute are possible.
Efficient coating for digital packaging printing
At the stand there will also be information on TRESU’s coating systems for integration with sheet-fed digital folding carton printing presses. These apply added-value full-surface and spot coatings as well as metallic embellishments directly after the printing stage. The TRESU Pinta is available for Xerox iGen presses, and the TRESU iCoat 30000 is designed for use with HP Indigo 30000 digital presses. Both perform at the same speeds as the presses and offer setup times of less than five minutes. Additionally,TRESU supplies a comprehensive range of consumables such as varnish media, tapes and sleeves, as well as cutting equipment, thereby covering every element in this coating workflow.
“We are very excited about attending Fachpack for the first time,” said Henrik Kristensen, vice-president, TRESU Ancillary. “This show has grown to become an important marketplace for both suppliers and brand owners. As providers of complete ink supply systems and printing lines for over three decades, TRESU has been advancing the quality, speed and production efficiency of flexography for packaging. With our stand presentations of equipment for all sectors of the flexo industry and packaging samples, we aim to show at first hand that flexo is the solution for building strong retail goods brands and maintaining margins in the value chain.”
