I didn't write you could use it in your printer. At most a paper coating 
with a similar texture but being white could be produced. I also 
referred to the walls in sound laboratories, there's analogy between the 
surfaces.

On the black + cyan Paul discussed. In CMYK offset printing it is quite 
normal to print black text and have the cyan plate run the same text 
underneath but the characarters slightly trapped to cover up 
registration faults. But that offset black is very transparant and 
really needs a kick to get some Dmax.
