Gauge Features
- External Varnish Thickness / Weight / OV (Over Ink)
- Rim Coat Lacquer Thickness / Weight
- Reverse Wall Inspection
- Dual system equipped with two spectrometers – Visible Light and Near Infrared (NIR) light, enables the OV/over ink inspection
- Brand-new fibre set up creating a smaller spot size to optimise measurement of rim coat and reverse wall, both with dedicated tooling to enable precise location of measurement positions on both features
- Enables monitoring and control of the lacquer distribution
- Absolute, not inferred, lacquer thickness measurement
- High positional accuracy, ensuring true location of measurement points
- Multi-size capability so no need for change tooling
- Traceable measurements to NIST standards
