a place for zinesters - writers and readers
I've had this problem several times. It's not the paper. It's a problem with the fuser cartridge in the copy machine. It's heat fused and if the heating element is not working right the ink doesn't adhere all the way.
VERY annoying when you have a black and white image that's intended to be colored in (as in paper doll designs). Have the place redo the job for you. Just show them that it rubs off. They won't argue.
