The ‘coloured film’ fused onto the self-adhesive film differs from other colour systems not only because of its high durability, but also because of its excellent colour brilliance. The plotter cuts the contour of the vinyl lettering into the self-adhesive film. Once the sheet has been plotted, the film material surrounding the vinyl lettering is removed by hand from the release paper.
The plotted film is weeded. After weeding, the remaining plot lettering is covered with a transfer film. The transfer film is used to pull off the vinyl lettering – consisting of individual letters and symbols – from the release paper, and transferred to the adhesive object by positioning it in one piece. Because sticking the individual lettering is done using a transfer film, the thickness of the film can be kept very thin at 50 µm.
A thin film provides little surface on its edges for a high-pressure jet, which are used to clean agricultural and construction machinery. For vinyl lettering, we use cast films which do not shrink over the years due to their high level of dimensional stability. This is why there are no adhesive edges around the cut contour where streaks of dirt can build up. It is also possible to coat the individual letters and contours with polyurethane to set a dome over the letters.
This creates a 3D effect and additional scratch and UV protection for the vinyl lettering.
