I assume that what JackieChan wants is just the background wave design without any pictures in Black and white so that he can place Kanji on it as a tattoo. Your best bet JackieChan is take a picture as you have done, make it bigger then print it off. Any good tattooist will make a trace of the background waves and fill in the missing bits covered normally by a picture. Then he can apply the trace using blue ink, then tattoo the waves design onto your skin followed by your choice of Kanji on top. Hope that helps buddy!

EDIT; if you can find a good quality picture of a pair of RMC with only plain waves on the back pockets ( prob an older design) and no picture maybe you could enlarge then print it off so the tattooist can do a direct trace of it with no picture in the way. Try this one;

Click on the image, it will take you to webshots, click on it again for the enlarged version then print it off on your printer. Good luck!
