How do I print images onto minifig body parts? I have seen a few custom minifigures out there with images on certain body parts never produced by LEGO. What is the best way to achieve this? I have heard of some people printing out the image on paper and gluing it, but I don't want to do that. That would look horrible even if I got the background of the picture to be the same color as the plain piece. I've also heard of printing an image onto sticker paper and applying it. That would probably work on a torso, but probably would do a bad job of deforming around legs, heads, or certain types of helmets. Anyone got any other ideas?
You can do that with scale model water decals. You can buy that in blank sheets and print out your designs with an inkjet printer. You can also use products that help those water decals set (adhere) and conform to the surface deformation and use scale model varnishes to seal it in place.  

Shopping list:


Water decal sheets
Setting solution (sticks better)
Solvent solution (conforms to the surface)
Varnish/Finish


As stated in this other question about painting Lego bricks: Don't expect it to sustain the normal usage of LEGO bricks. This is good for display or light usage (like playing D&amp;D with custom minifigures)
