Not to confuse it with relative humidity maybe it should be called Total
Water Weight (TWW) or Total Available Water (TAW).

Assuming no other parameter interacts such as temperature. These other
parameters can be noted as well. But first we must identify what they
It does seem reasonable that the amount of water (by weight) available
for reaction would be the thing to monitor along with the other critical
parameters. Although for printing, the technique of weighing and
adjusting by drying or humidifying and re-weighing may be more
mechanical effort than necessary.
