is there a trick to put Tattoos on figures?

Posted in Custom Workstation

well im working on a few Custom figures, of character I have made in WWE games, and the first figure is my WWE version of me, so im using the new Mattel line John Cena. But I have some very unique tattoos that the figure would have to have also (praying hands of "the predator" with skull rosary and a queen alien head for a crucifix on my upper left arm, a alien and a predator running at each other on my back, three red dots also on my back, and the Hybrid "predalien" portrait on my left leg). so is there any tricks to put tattoos on a figure? or am I going to have to take a small ass brush and try to free hand them? (because they will come out horribly if that the case)
