Ceramic frit white on black dots printed on glass

Contra Vision® XR Ceramic™

White or decoratively coloured dots can be printed in exact registration (without any overlap to the naked eye) on top of black dots with Contra Vision® XR Ceramic™. A simple white on black dot pattern adds solar control, privacy and manifestation to the outside of glass while maintaining a remarkable level of through-vision from inside.

White ceramic frit dots provide solar benefits to glass

White ceramic frit dots are often added to the glass on modern buildings to reduce solar heat gain, glare and UV radiation. There are many architectural applications for Contra Vision with a range of additional benefits including privacy to people inside buildings, manifestation (making the glass more visible to avoid accidents, reduce bird collisions etc) and even as a screen for digital projections and light displays at night.

The problem with white dots is they do not create the best visual experience from inside the building. The view outside is not blocked but it appears cloudy and white dominates the colour spectrum. Black dots provide a much better viewing experience because black absorbs light (so the presence of the dots is less noticeable).

Black dots allow better see-through from inside

Contra Vision® XR Ceramic™ is manufactured by applying a print pattern of ceramic frit onto annealed glass. The Contra Vision® effect is achieved by applying two separate layers of the print pattern in exact registration (exactly on top of each other with no overlap) using a patented method. Typically the ceramic frit will be printed on the inside surface of the first piece of glass in a glazing installation (surface 2). The first printed layer (layer 1) is seen from the outside (often white but a wide range of colours are available to add decoration to a building) and the second layer (layer 2) is black which allows good see-through from inside. After the ceramic frit is applied to one side of the glass, it is fired within a tempering furnace to create a permanent coating.

A variety of print patterns and designs are achievable

As well as different colours, layer 1 can also incorporate simple graphics, lettering and corporate branding. The print pattern can also be varied depending on requirements, with line patterns as well as dot patterns an option depending on the one-way vision effect which is preferred. The size and density of the dots/lines is also an important consideration for achieving the desired level of transparency, one-way vision impact and solar control. Dot patterns can cover as much as 60% of the surface area and the smallest we can print them is about 1.5mm diameter.

Beware of other printing technologies. Ceramic frit dots can also be digitally printed but not with two layers in exact registration. The through-vision will appear blurred because of overlap between the colours. 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.
