Newspaper Printing Nip Roll Settings

Nip pressure, uniformity, and setup are critical factors for mass newsprint printing machines.

Setting Nip Pressure for High Volume Newspaper Printing Using Pressure Measurement

A major Newpaper publisher and printer recently contacted us for help with maintaining their printing quality and efficiency.

Challenge

Nip pressure, uniformity, and setup are critical factors in the newspaper printing process. A misaligned roll can lead to poor print quality, paper handling, ink transfer and density control. Proper alignment ensures minimal wear and tear on the rollers, and maximizes efficiency.

Solution

The NPAT Nip Pressure Alignment Tool is a key diagnostic and machine set-up tool for balancing NIP. The NPAT is used to capture nip footprints and relative pressure distribution between nip rolls. The NPAT sensor band array can cover a very large area while utilizing one data acquisition handle. The system's minimally intrusive sensors can be positioned adjust blade height, pressure and tightness, ensuring the desired pressure distribution along the length of the blade is achieved.

The NPAT pressure mapping system allows for real time viewing of the pressure and can capture and display the pressure pattern during the manufacturing or printing. With the help of Tekscan's highly qualified sales and engineering support team, each system may be configured to meet your specific needs.
