Then printed them out on Laser decal paper. (cost like 2€ for an A4 sheet). Worked out great.
Below the decals I made (left) the samueldecal Sinanju set (bottom right) and a generic warning decal set in 1/144 from samuel - I prefer 1/144 decals on 1/100 kits, looks more to scale then man-sized warning decals that 1/100 ones are :)
For the sleeves I primed the plastic with black canned lacquer first, the sprayed Alclad2 Pale Gold over it.
Then I sprayed Revell flat black email color over it.
Then I wiped off the raised areas with lighter fluid and cotton buds. Worked out great but Alclad comes off easier than you'd think -_-
Have to redo a bunch of parts, but generally it works great.
