Etch Effect Window Graphics

Etch Effect Window Graphics - AppliedEtched windows are very well known and a number of means and practices exist which support their manufacture including Etch Effect Window Graphics.

Glass used in glazing typically comprises a glass sheet, a pane, of the required dimension with a first and second surface. Both of these surfaces are substantially plane and substantially parallel to each other. Such a pane yields a uninterrupted view through. The view may have a slight colour cast which is dependent upon the body colour of the glass which is often greenish. Low iron glass varieties do not have such a tint.

To achieve a decorative effect, privacy or branding, glass is sometimes etched. One means of etching glass is with the application of a chemical such as hydrogen fluoride. Such a chemical will modify the plane nature of the glazed surface to which it’s applied imparting a finish that tends toward structured, micro-crystals when observed at high magnification. This finish obstructs the clear view and yet admits light and contrasts dramatically with surrounding unmodified areas.

Glass can be etched mechanically too. The most popular means of mechanically etching glass is with an abrasive medium, such as aluminium oxide or garnet, blasted at great speed using compressed air through a suitable stencil. This imparts an effect similar to that achieved by chemical etching and, like chemically etched glass, the effect is permanent.

Both sandblasting and chemical etching are difficult and disruptive in their application to installed glass in situ. The permanent nature of the application is sometimes not desired. Some studies indicate that mechanical modification of glass can be the source of weaknesses and stress concentrations sometimes causing cracks to propagate.

Contemporary etch effects are achieved using the application of an etch effect film so creating Etch Effect Window Graphics. An etch effect film is typically self adhesive and is simply cut, using a computer driven cutting plotter, to the shapes required, which are then applied to the glass. The effect is dramatic, barely distinguishable from etched or blasted markings and can be removed when required.

Etch effect films are available in considerable variety each imparting its own effect to Etch Effect Window Graphics. For example, films are available with inclusions in the mass of the material that sparkle in direct light. Films are also available in that impart a slight colour. More recently, films that are receptive to print have been introduced. These films can be used to achieve ambient effects supporting brands or purely for the decorative benefits Etch Effect Window graphics deliver.

Etch effect films can be used in concert with other self-adhesive media to create highly detailed window graphics that are both attractive and functional. Etch effects used in interiors, on panels in partition structures for example, achieve a degree of privacy and are valued for their decorative effects too.

One Way Vision Window Graphics

Contra Vision Exterior View delivers great image impactOne way vision window graphics, also known as see-through graphics, enable the use of windows, or any glazed panel, for the deployment and display of advertising messages, decorative effects, security or privacy measures, and directional signing among other types of printed and applied graphics.

Applied one way vision graphics are also commonly referred to as Contra Vision or Contravision. Contra Vision is in fact a trademark that identifies a UK and USA based company of the same name and many of the products and technologies, supporting the production of one way vision graphics, which it sells or licenses to other materials manufacturers.

A typical one way vision graphics will comprise a design printed upon a specialised perforated window film. The film further comprises a white surface, a black surface and an adhesive layer the whole assembly being provided with numerous perforations arranged in a staggered pattern.

The design is printed on the white side of the film and then the whole assembly is adhered to a window or other transparent panel. The design will be visible to observers on the design side of the panel, while those on the other side will see through the panel as though the applied design were not there at all.

Being seen from one side and not being seen from the other, enables the use of windows to display graphics even in locations where a view out must be maintained. It is known for whole buildings to be wrapped in such materials thus creating landmark scale advertising statements.

Contra Vision delivers a clear view out and privacy  for those inside.By carefully managing light levels, it is possible for graphics manufacturers to create, for example, window displays where the applied message itself can be seen through to an article beyond. This practice is used to extend the reach of point of sale campaigns to the pavement outside shop windows and is know to be very effective.

The use of one way vision graphics materials and Contra Vision products in particular has become very popular in the field of privacy. It is often desired to maintain a view through a window from the interior of a building and yet stop those outside seeing in. Privacy window films, including perforated window films accomplish this at little expense. Applied films are often left unprinted.

One of the major areas of application for one way vision window graphics is transport advertising. Typically applied to the windows of bus fleets, such graphics deliver out-of-home advertising campaigns on behalf of major brands and exert influence in pedestrianised zones where other forms of advertising might be regulated.

Careful selection of the material used to produce perforated one way vision window graphics can influence the strength of the image displayed versus the degree of see-through accomplished. Typical percentage include 80/20 in favour of the image, 60/40 30/70 and 50/50.

Digitally printed one way vision window graphics are available in very low volumes or where data is variable.
