Personally i wouldn't bother trying to print your own cf decals. You'd have to design the weave yourself, print one colour over the other, seal the decal with varnish/laquer and then at the end of it it could be brittle and not work at all. A cf decal that's difficult to work with and doesn't conform well with microsol will be a nightmare. There's loads of companies doing cf decals in 1/20 which will work fine in any and every shade that you want, including clear nowadays.
