The idea with home made waterslides didn't work out well for the large decals. Since it is difficult to cut out the tiny detailed stuff with scissors freehand, I used a black background. The contrast between the black paint and the decals was too big.
Now all decals have been cut out of white vinyl foil. Some attempts in vinyl didn't work out, because the design is very detailed and it requires i-cutting. Freehand cutting of vinyl was no option.
Quite some work to make the final artwork (I worked out many versions including colours, printing, multiple layers ink or vinyl, etc) and appearantly not easy to cut. It's a combination of filled letters and outlines (less than 1 mm).
I've just applied the stuff and clearcoat has to follow. I'm happy with the result. It's about 99% of what I had in mind (okay, still the easiest and cheapest version) and it came out nicely.
The coloured Columbus frame and fork decals are home made waterslides (decal paper for a laser printer).
