it's very hard to find out the effects of each dithering methods 
(except "fast" and "very fast" are not adapted to fine BW prints).

The thread from photonet states that only ordered,fast and Adaptive 
Hybrid are implemented in QTR ?

The one from sourceforge seems to recommend Adaptive Hybrid since 
ordered is only preferable for 4colors none variable dot sized 
printers, A/H would use error diffusion in dark & halftones and ordered 
in light tones.


None of these papers is too explicite. Any additonal comments from 
better experimented people than me...
