A selection of Traffolyte engraving clips, detailing the process, and how Traffolyte signs are engraved
Just to recap, Traffolyte engraving is so-called after the birthplace of the method: Trafford Park Industrial Estate. The plastic was originally derived from phenolic plastic sheets. There are standard colours with, for example, a Traffolyte sign being made of a top and bottom red layer. Like a liquorice allsort or a strawberry split ice lolly, it has a ‘bit in the middle’. For arguments sake, this may be white. Text is die cut onto the top and bottom layers of the ‘sandwich’.
