It's a type of corrosion, called "Aluminium-Frass" in German (heck, cannot find it in English...), it's an autocatalytic reaction, so it will spread out (even below the printing), requiring H20. Feeding more water to it (or leaving it exposed to the air humidity) will eventually completely eat up the metal, leaving only a bit of white powder...
