[Future versions of Kaala/Kaalink are a proprietary technology pursued by MIT Spinoff Graviky]
What if the air pollution could be repurposed to generate printing ink?

Black printing ink is one of the most consumed products in the industry. Most of this printing ink is produced in factories with complex chemical procedures. Companies like HP/Canon make 70 percent of their profits by selling these cartridges at 400% margin.
Just a minor itch that led me to build something cool from observations arising from nostalgia of the days back in India. There's so much soot/pollution around us, esp. in crowded cities.
Our method here shows air pollution repurposed to be used as printing ink. Printable via ~ 100dpi print platform.
'kaala' stands for black.
