I've had good luck using decal film from Bare-Metal.com. It comes in clear 8-1/2 x 11 inch sheets that can be fed into your printer. I scan the decal or artwork as a jpeg file, then insert that into a word document page. Once it's inserted into the page it can be manipulated for brightness, contrast and size. When you have the desired size and color it can be printed out on the decal film. The decal film is available for inkjet and lazer printers. Besides clear film it also comes in white ( just in case the decal has a white background). Once it's printed on the film, give it a light coat of clear gloss coat or clear flat coat to keep the colors from running. Hope that helps.
