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.
