I have been using Testors decal paper for ink jet printers for years. it comes in both white and clear. Once you get the graphics in the computer, you can resize them to what ever you want, and then print them with your printer. They recommend a decal sealer spray for them, but I use clear butyrate dope brushed on to seal them. After they are applied I brush a few more coats of dope over them to bond them and seal the edges to the dope finish.
