armed_and_christian gives us this heads up:
Printing ink (i.e. from an actual printing press) won't run, but toner (from a copier) will. Not so certain about inkjet printer ink, You'll just have to check it out and see for yourself. The paper's weight is much less a concern than the type of ink.
Silk Screen Printing Apparatus.
True enough. All the posters I put up in my mis-spent youth were either silk-screened or printed on a press. So, be advised. Find yourself a resistance printer. Good to know before the balloon goes up anyway.
