The carbon fiber composition gives the chamber high-strength qualities, which has a weight of between 2.4kg and 4.1kg per linear meter (approx. 1.6 lb. – 2.74 lb. per linear foot). The inside of the chamber features a top-coated ink-repellent surface. This offers extra protection against ink and detergents with high and low pH-values and ensures efficient cleaning after job completion.
In addition, curved inner surfaces maximize volume and facilitate controlled discharge. The chamber’s design also enables ink and coating circulation in relatively low volumes.
The units offer pressure-controlled ink and coating circulation with manual or closed-loop control systems, like the Tresu F10 iCon Ink Control System. According to the company, they feature Tresu’s patented seal system, preventing leakage, and stainless steel blades whose clamping system enables one of the fastest possible changeovers in the industry, of within two minutes.
“Thanks to its time-saving advantages, optimized fluid control and resilience, the TRESU carbon fiber chamber offers a long-term solution for high productivity, low ownership costs and uniform quality," says Henrik Kristensen, vice president, Tresu.
The enclosed environment 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. This is designed for a clean, blister-free printed image with fast drying characteristics, better reflection and higher gloss values, whether on paper or film.
The enclosed chamber also prevents solvents from escaping and protects the ink from degradation due to exposure to the atmosphere.
