Unsolved Mystery of the Disappearing Print Ink
September 29, 2012 10:12 PM Subscribe
What is this non-permanent printer ink I've received in a print? I didn't know that ink could
be erased with a simple pencil eraser, but indeed the postcard-sized print I received on relatively heavy paper (possibly watercolor paper) was erasable with a pencil eraser. I only wanted to see if I could slough off a speck of dirt, and instead skin color came off the portrait. What's going on? Is this kind of ink going to fade and disappear in a couple of years even under glass?

For detail, I received this as a reproduction of a 5x7" watercolor painting (definitely a medium that resists erasers). I'm not sure what sort of printing process was used-- that's kind of the mystery. I've tested my eraser on inkjet printer ink and the ink wouldn't smudge, so it's not a magic eraser. I'm not sure if this is just the cheapest ink in the world or what-- I tried searching for 'non-permanent printer ink' and only found markers. It's not vital since it was pretty cheap and need not last that long, but I probably wouldn't have paid even this much for erasable ink. Now I just want to know it really does exist.
