Following tests with wet ink the paper is clearly showing splattered ink particles.
Exactly the same process occurs during laser treatment of tattoos. The ink particles are enclosed within macrophages and fibroblasts in the dermis, with encapsulated tissue water.
As the ink particles heat up, the surrounding tissue water forms steam and causes the cells to rupture. In addition, some of the ink particles fly out of the skin at very high speeds.
I spotted this some years ago and published a paper with my observations - click here for that paper. I calculated that some of those ink particles could be leaving the skin at around 700 metres/second!!
I'm currently working on the physics of all this stuff - it's very interesting. I'll let you know once I'm done...
Ciao for now, Mike.
