The best kept secret is an Asymmetric chamber design, in combination with thinner doctor blades!
About 10 years ago the first truly asymmetric chamber NOVA XLS was introduced by AkeBoose Graphic Products. The Swedish engineer Åke Bööse had found out that different blade angels are the key to eliminate problems with back doctoring. The results also proved to be even better when using thinner doctor blades. By using a high quality sealing/retaining blade of 0,15 mm thickness, at a flatter angle, the thin and flexible sealing blade allows superficial ink droplets on the screen roller, to re-enter the chamber, instead of dripping down or spreading side-ways to the roller ends.
The NOVA XLS Closed chamber is the most flexible model within the NOVA family. The truly assymetrical chamber can be fully automated, fitted with Pump & Washing systems and/or the new HumidFlow system against quick drying ink around the end-seals.
NOVA XLS Closed is developed from an assymetric single body chamber, designed according to two major principles; inking perfection and easy cleaning. The assymetrical design eliminates problems like back doctoring, ink starvation and ghosting thanks you optimal blade angles for working- and sealing blade and the low pressure doctoring principle.
