Digital BW, The Print

Thak you for your precise reply. About the viscosity  of carbon ink 
,the i850 the black ink uses carbon and appeared to be less 
metameristic(?) and in fact am trying an experiment soon when i 
have more time. That is to use carbon black ink from the i850. 
Can't wait to see the new 8 ink HP although the small cartridges
and high price are OUCH expensive.
