Self adhesive vinyl lettering began replacing painted signwriting back in the 1980s and has long been universally accepted as a better alternative to paint, particularly when used for vehicles, as it is removable and designs are more easily reproduced.
Vinyl is still arguably the best form of graphic material for most external applications that require long life and colour stability. Unlike printed material, a quality polymeric or cast vinyl will last around 7-10 years outside.
Pantone colours are primarily designed for printed materials, so a limited number are available in cut vinyl, but if specific colours, gradients or photographs are required, then vinyl can be printed and laminated to increase durability of the inks.
