Vitreous enamel provides an ideal medium through which practical as well as artistic solutions such as signs, graphics, company logos and murals can be incorporated into the design of a building.

Vitreous enamel signs have been around for a very long time, some having become sought after collector's items. The combination of a hard glass surface that envelops a steel substrate has ensured that the signs have endured and are highly sought after.

Vitreous enamel signs continue to find a home with specifiers that demand strong colours and a high level of weather and vandal resistance.

Large sign panels carrying multi-coloured graphics are being used to brighten the environment, public places, schools and work areas. In Europe, after experiments with street signs made of plastic sheet during the 60's and 70's, cities and towns are reverting back to the use of enamel signs.

Various application techniques can be adopted depending on the complexity of the artwork and the detail required, in general however, each successive application of enamel screening paste for the image is individually fired through the furnace at a temperature of around 740ºC, which is some 60ºC lower than the firing temperature of the base coat enamel. The base enamel becomes soft and there is fusion between the enamel of the image and that of the panel.


  • Masking: Most basic form, used to produce simple straight lines or panels enamelled with two different colours, involves a special rubber masking material.
  • Transfers: The transfer is created by sequentially placing layer upon layer of differing colours of enamel screening paste onto transfer paper, with silk screens.
  • Block Colour Printing: In general, this is the method used to produce logos, station names and similar text work.
  • 4-Colour Separation: The image is produced by printing the 4 separated colours in a set order onto a fully enamelled panel, with cyan being the first colour and black the last.
