By ways of photocopies, laserprints, color pencils, photos, body and nail
tattoos, inkjet prints on photo paper and t-shirt transfer paper and a lot
of other media you can transfer graphics and drawings to polymer clay. I
have even seen exaples of a very thin baked sheet of clay run through an
inkjet printer! There's just no end to the imagination and innovation among
clayers.
Transfers may be one of the hardest techniques to master, but it CAN be
done.
