Danish polyethylene packaging supplier Trioplast Nyborg has halved setup times to two hours after modernising its 4-colour Fischer & Krecke 1,650mm CI flexo press with Tresu Ancillary's FlexiPrint chambered doctor blade and F10 iCon ink supply system.
Frank Jørgensen, operations manager at Trioplast, comments: "The ink supply offered obvious potential for improvement because the existing open trays allowed excessive evaporation and required constant replenishment with solvent. We had already experienced significant performance and safety improvements as a result of installing the Tresu systems on two 6-colour CI presses last year. It was a natural step for us to repeat this investment, and it is meeting expectations: we have eliminated the escape of vapours, cut cleaning to half an hour per printing station, and achieved uniform, clean ink transfer at speeds of up to 110m/min."
The F10 iCon circulates the ink at stable, easily adjustable viscosity, pressure and temperature levels, and completes an ink change within 10min. It also stores flow settings of every colour on each job, which can be automatically recalled without the need for manual data entry.
The FlexiPrint doctor blade system ensures uniform ink transfer directly to the anilox cells, without air being trapped at fast speeds. Pressure is adjusted to exact levels required to form a wall of ink at the point where rotating cells meet the blade, preventing air contamination and foaming.
