Blackwork Tattoo like the name say it’s that getting a tattoo in black ink, can be in any style like lettering, traditional, neo-traditional, japanese, tribal, blackout, suminagashi, etc as long as is in black ink.
it’s really usefull for coverups and it’s the type of tattoo that looks better with time since color tattoos don’t heal looking as good since the color dissapears or just does not looks as good at when your tattoo is fresh.
