Why is the roller nip so important?
The roller nip is critical for offset printing since it both transports and processes the ink and fountain solution. This technology is unique in that the process components, ink and water, are mixed under pressure during printing, creating a new solution.
Contact width - estimated by applying ink to the rollers, rotating them and measuring the width of the stripe - varies according to type of ink and final viscosity after mechanical mixing. The dynamic properties of the rubber roller constantly change too. The rubber ages, hardens and is also affected by the heat generated from friction during printing.
The Nip Control digital measuring system has been designed to generate improved roller nip data and to ensure that the roller nips are always correctly adjusted.
Precise, clean and consistent.
