The Nip Control device, the Roller Nip Indicator, featuring a dynamic sensor, measures the nip width relative to a pre-determined dynamic pressure level between the rollers (Rolling NipTM). The instrument incorporates viscoelastic changes, preventing deviation in roller nip pressure that could destabilise the printing process.
