Reading the instructions for changing the ink on a Epson printer I saw the
instruction to Shake the black ink - but don't shake the coloured inks.

If I knew why I would probably remember it correctly. Any ideas?

WEll maybe the particles in the black are not really stable in solution but
if that were the case surely after a short time in use the black would start
acting up.

I assume the black is pigment based so shaking will disperse the tiny
insoluble particles of black through out the liquid medium, whilst the
colour is dye based so fully dissolved in the solvent.

My Canon iX6850 printer has a large pigment based black cartridge and a
smaller dye based black cartridge.

And shaking the dye ones unnecessarily may introduce small air bubbles
which subsequently cause problems?
