Q. I’ve heard about people copying drawings onto watercolor paper using a copier, but when I tried it, the ink bled. Is waterproof ink available for home copiers?
A. Yes, I’ve heard about this, too, and have done it. Your home copier, however, probably uses water-based inkjet ink, which may be the cause of the bleeding.
Try taking your drawings and some watercolor paper to a copy shop and have them use a resin-based ink copier like those made by Xerox or Canon. That should keep the ink from smearing when you apply water to the paper’s surface.
