I might also be tempted to run the same experiment with some vacuum,
as I suspect the trapped air hinders the absorption, but I don't want to
vaporise the ink and fill my vacuum pump with water...

"But, but, but Science!"

De watering the vacuum line is "Merely Engineering(tm)!" (aka
"just money")

I can see a method of a vacuum pump hooked to a tank, which gets
pumped out, the line to the pump closed, then the line to the sample
chamber open. But as you said, you'll still be pumping water out of
solution, thus changing the concentration. Of course, you could seal
the sample so that it gets the vacuum, and not the entire container.

"Why don't you try that and write it up?" B-)

With that setup you can also fill the wood with plastic resin.

I boil wood in paraffin wax to weatherproof it for outdoor use, like pulley
sheaves and antenna insulators. The above-boiling wax makes the water sizzle
out. The urethane wax in toilet bowl rings is less brittle at low
temperatures.

I've been using a small Gast rotary vane pump on my vacuum oven if there was
much water to remove, and running it open afterwards to dry it. Has anyone
had a problem doing this?
