Well, Mycie, i don't mind having another test to quantify the effects of
wetting agents, but it doesn't really seem to solve any problems. I mean
it is easy to see from the printout if one has had enough or too little
wetting, and application of the agent can be adjusted accordingly. This is
what you'll end up having to do no matter if you previously experimented
with ink drops.
If you think it helps to study wetting agents - be my guest, but since
Volkan gets good results without any wetting agent it doesn't seem like
it's the key element.
IMO wetting agents just make the cleaning less critical, that's what i've
observed anyway.
