The overprint will work as long as BLT puts down the pipe. Just need super opaque white and maybe hit it twice. We've printed a couple like this. Most the white ink on black paper we have are hit once sometimes twice. (Doves. Pong, Juliana Theory)
Thanks for the nice comments!
Orange may be this year's pink, but pink is next year's brown. And Polar bear's are this year's tigers.
Thanks again. I'm a little nervous about the white overprinting. Never done that...
