Tresu Group has introduced a new compact system designed to regulate high-viscosity packaging varnishes.
The new XL5i Coating Circulator is designed to ensure precisely regulated, stable flow, and uncontaminated print and coating, when applying sensitive UV and water-based varnishes for packaging and label applications.
Tresu Ancillary vice-president Henrik Kristensen said: “Varnishes responsible for high lustre, brilliant colors and appealing tactile effects are powerful ways of adding brand value - especially for luxury and personal care packaging, where a striking point of sale impact is crucial to achieve sales.
Featuring two speed-controlled peristaltic pumps, the Tresu XL5i offers semi-automatic cleaning and timer settings to allow customers to operate it easily.
The machine can be used in combination with a chamber doctor blade and customized open-cell anilox roll.
The company said in a statement: “The system provides fully enclosed circulation from the bucket to the point where the ink or varnish fills the anilox cells, thereby enabling pressure and control needed to delicately handle the medium.”
The enclosed system prevents contamination of air inside the chamber that can lead to foaming and undesired blistering of the printwork.
The XL5i can be used for printing applications including opaque white, gold and silver metalure, pearl lustre, blister coating, scented, high-gloss, scented or silky soft touch effects, on folding carton, self-adhesive labels or metallised papers.
Kristensen added: “TRESU’s XL5i circulator ensures these coating media are carefully handled with care, at precise viscosity and pressure levels, so the desired print result can be achieved without disturbance at high production speeds.”
