Ink/Coffee Spill Effect Across Paper

I am currently working on a scene that requires an ink spill effect. While I have found plenty of tutorials for ink drops, into water, the only one that I could find that closest fit my needs is:

The problem with this one is that it only affects a minimum area around the lettering, while I need it to spread over the entire plane. To put the scene in context, someone spills over a cup of coffee onto a book page, the camera zooms in as the fluid seeps into/across the paper.

I tried just a fluid simulation, but that doesnt quite cut it. Maybe smoke?
