Kolding, Denmark - Global flexo technology provider TRESU Group extends its enclosed chamber doctor blade programme by introducing the MaxiPrint Concept. A light-weight carbon-fibre or ceramic chamber, MaxiPrint Concept comprises a chamber doctor blade, inking system and cleaning system. Suited for wide-web and corrugated flexo applications, the concept offers corrosion-resistance; fast, automatic internal cleaning; improved quality consistency and reduced ink loss.
Available in widths of 1600mm to 6000mm, the chamber features an integrated cleaning nozzle with a robustly designed water-shot mechanism, to ensure efficient cleaning of the chamber and anilox roll in a short time. The shot mechanism maintains a low pressure, limiting water loss during the cleaning cycle.
The chamber offers significantly faster emptying performance compared with alternative chambers, because the ink or coating fluid is evacuated through both the chamber’s inlet and outlet. The fast drainage of the chamber, further assisted by rounded internal surfaces, facilitates thorough cleaning: the subsequent washing process can begin before any residue can dry on the anilox roll or inside the chamber. The ink change and cleaning cycle is typically completed within approximately five minutes.
The MaxiPrint Concept features TRESU’s patented seal system that prevents leakage and interaction of the chamber contents with the atmosphere. The enclosed environment, resulting from the seal and precise blade positioning, ensures pressure and flow rate are maintained at desired levels without manual intervention. This stops air contaminating the chamber and results in foam-free transfer of ink / coating directly to the anilox cells, also at fast speeds. The TRESU P-Line pneumatic clamping system also ensures fast, safe blade exchange within two minutes.
Henrik Kristensen, vice president, TRESU Ancillary, comments: “Traditionally, the productivity of wide web printing presses has been compromised because of the intensive manual effort required to clean the complete ink system. This is especially the case in wide-web and corrugated printing when several printing stations are typically operated. MaxiPrint Concept programme, with its robust, stable construction, automates this process, reduces ink loss, shortens setup times and ensures quality consistency.”
MaxiPrint chambers are available with a carbon fibre (CFC) or ceramic surface (CFX), offering protection against ink, coating media and detergents up to pH12. Weighing between 2.4kg and 4.1kg per linear metre (approx. 1.6lb – 2.74lg / linear foot) carbon fibre surfaces are lighter than the more economical ceramic alternatives, thus offering safest handling. TRESU has also extended its carbon fibre chamber doctor blade programme by introducing six-metre wide chambers, thus providing lightweight, corrosion-resistant solutions for all flexographic packaging printing applications.
The chambers are retrofittable and are compatible with closed-loop systems such as the TRESU F10 iCon Ink Control System.
TRESU will be exhibiting at drupa 2016, Hall 10, Stand D54.
