Large areas of glass have to be marked with manifestations of some description to prevent accidental collision, however the way in which glass is marked can lead to both elegant signage and a real promotional opportunity. Using the latest advanced films the illusion of etched or frosted glass can be created at a fraction of the cost. This means that in the office location manifestations can also communicate corporate branding, and for retail outlets safety and effective promotion go hand in hand. Apart from manifestation markings, large areas of glass can be used to promote specific products and services using a wide variety of colour and photographic signage.
