Wonder how pure that carbon is then :-)
In a practical sense and for people living outside the US it may be 
easier to use the HP Vivera source and rely on the good tests results 
instead of going for the pure carbon goal. The same PDF quotes HP Vivera 
PK as being neutral and I can add HP Vivera MK in that category too. The 
Vivera Grey inks can be used as well but more than the PK they tend to 
give bronzing on most gloss papers. PK diluted with transparent ink 
media gives better results and will be cheaper. I use an OCP gloss 
enhancer for that and an HP K5400 with thermal heads to print with, ink 
and ink medium suit the thermal heads. Paul uses one type of MIS ink 
medium to do the same for pi\ufffdzo heads. 130 ML or larger carts of HP 
Vivera inks are not that expensive and easily available.

The Photorag Bright White gets warm quite fast in time.
