Contra Vision® XR Ceramic™

Contra Vision® XR Ceramic™ is manufactured by applying a print pattern (usually dots) of ceramic frit directly onto glass. The dots are a different colour when seen from each side of the glass, which creates a one-way vision effect.

From outside the dots are white or brightly coloured for decoration, privacy, solar control and manifestation. From inside the dots are black to allow the best possible see-through. Contra Vision’s  patented exact registration printing ensures that each colour is only visible from one side of the glass.

Key features

  • Available in a wide range of colours;
  • Simple graphics such as lettering can also be achieved;
  • Various print patterns including lines and hexagons;
  • The size and spacing of the print pattern can be varied to achieve a desired level of transparency, one-way vision privacy and solar control.

Black dots allow excellent see-through from inside

A red dot pattern was added to the outside of the Nova South building in London. There is no hint of red in the glass when viewing from inside (see photo of London buses left or above).

Beware of other printing technologies. Ceramic frit dots can also be digitally printed but there will be discernable overlap in the colours. This impacts the quality of the see-through from inside the building, making it blurred. Other types of ink can be used to print more complex graphics including photo images. However the inks are less durable than ceramic frit and will start to fade in direct sunlight within 10 years.
