Accurate tension measurement and control can go a long way toward reducing the negative effects of process deviations on printed and converted materials in a continuous web process, particularly in cases where flexible, extensible substrates are being run. Physical inconsistencies of difficult substrates can also often be compensated for. Even a press with sophisticated register controls can benefit from the refinement in output quality brought by an accurate transducer-based tension system.
By reducing web scrap and allowing a web press to run at higher speeds with defect-minimized output, a reliable web tension control system will not only improve a press’ bottom line performance, but can often pay for itself in as little as a few weeks. It’s a relatively low-cost machinery upgrade that improves productivity, reduces process waste and makes a converting business more competitive.
