Digital BW, The Print

I thought the procedure for getting carbon pigment(ed) ink was as follows:
  Sharpen 5000 2B pencils to stubs and hopper the shavings (they use the 2B
to get the blacker carbon, I understand)
  Run the pencil shaving through a special wood shaving extractor, or burn
in an ashtray;
  They then use a **** multichef to mix the carbon in with the liquid
carrier and add a bit of dye (dependent upon which ink is being
manufactured).

The liquid ink is then piped into the cartridges, and left to stand for two
hours before sealing (the carts).

Hope this is helpful to someone ;)
