Digital BW, The Print

On the design of CIS systems. Might it be better to use slightly larger
ink tubing? Just a thought.

Anyone know if a drop of photo flo might help the inks flo better?  Or
some other wetting agent that was more or less also an anti foam agent?
Photo flo probably has too much foam to be useful with a moving cartridge.
