I just got my custom decals by mail. They are intended for my two 1/72 OH-6As and for my 1/24 Volkswagen Bus. I have drawn them in CorelDRAW! and the sent the patterns to a decal printing company in Poland. They took unusually long this time - about a month - and now I got my decals:
As you can see they print white and silver. You can also see that I ordered two sets at once, so that in case something goes wrong I have a spare, that makes me a lot easier when applying them. The sheet is printed on continuous film, meaning you have to cut the decals out, but the film is very thin and dissolves with set&sol no problem. The colours are "underprinted" with white, so there's no problem with coverage. Like I always write, in my opinion it's a lot better option to design your decals and have them custom printed than investing heavy money in Alps printer or something like that. By the way - this sheet has cost me 50 Zlotys - about 12$ including shipping, so that's not too bad, is it?
Thanks for reading and good luck with your modelling projects, have a nice day
