Not made wet or damp; dry.
The unwetted surface of the paper absorbed the ink poorly.
Unwetted → It is formed from "un-" (meaning not) and "wetted" (the past participle of "wet", which comes from Old English "wæt", meaning moist or damp). The word "unwetted" means not made wet or not moistened.
Think of 'not' ('un-') making something 'moist' ('wetted') — that's why unwetted means not made wet.
