Great savings when connecting Humid Flow® System with NOVA XLS Chamber System
NO MORE CLOGGED AND LEAKING END-SEALS
NO MORE TIME CONSUMING INTERRUPTIONS
INDIVIDUALLY CUSTOMIZED TO YOUR SYSTEM
When using quick drying waterborne inks for flexo printing, lumps of semi-dried ink tend to destroy the function of the end-seals. The new HumidFlow® System prevents waterborne inks to dry up and push the end-seals out. No more unplanned production stops, due to clogged end-seals leading to heavy leakage. No more ink dripping from the sealing blade. No more possible contamination of linear bearings by drying ink, in printing units of sophisticated Flexo printing presses.
The best kept secret for inking and doctoring efficiency is a truly asymmetric chamber system as NOVA XLS, in combination with low-pressure doctoring. The two principles allow the chamber to work with optimal blade angles for both working- and sealing blade, which eliminates problems with back doctoring and ink spitting.
When using quick drying waterborne inks in an enclosed chamber, the function of the end-seals are easily destroyed by lumps of semi-dried ink. Typically, the semi-dried ink builds up underneath the working blade, and thereby pushes the seal and the blade away from each other, allowing the ink in the chamber to flow out without restraint.
With the NOVA XLS ink chamber and the HumidFlow® System, the problem is solved by a double end-seal arrangement, that keeps the area around the seals at a high humidity, preventing the ink from drying in this area. No more unplanned production stops, due to heavy ink leakage at both ends of the chamber/screen roller and no more unnecessary cleaning work. Just great savings in manpower and running costs! Not to mention the possible contamination of the linear bearings in each print deck of electronically controlled flexo printing presses. Ink should never be allowed to enter such bearings!
