N-propyl alcohol versus Isopropanol alcohol

[shogom]

I agree with scooter. IPA breaks down surface tension, essentially making your water wetter than it was before. Unfortunately alcohol also breaks down ink in the rollor train causing it to emulsify prematurely and eats away at pigments causing dryback and fading of the ink. Glycol and glycerin compounds in alcohol subs are still alcohol, just a different kind, more like what you would find in antifreeze and do not evaporate.

Any opinion about archetype's comment?I have some problems with the inks glossy and i want to verify the IPA dosage.
thanks.
