Have you tried Sinopia or Kremer pigments ? Were the watercolor pigments dry
or already mixed with gum arabic ?

The pigment particle sizes need to be correct, and I believe 
dispersants are added at the ball grinding stage. The water color 
pigment I bought and used would not stay in suspension well enough to 
be used for other than testing. It also did not print as smoothly as 
it should have. So, I think more is needed than just putting water 
color pigments into a good base and filtering it to eliminate the large 
particles.
