I would guess that the odd number is to avoid it being a [higher] harmonic
of something else (native resolution, spatial sampling frequency, ...)
I've heard this type of advice to avoid aliasing-related artifacts.
I have some intuitive feeling why that *might be* the case, but I don't
understand it at any reasonable level (and definitely far from being
able to explain it).

There used to be a real good Pro-Lab located about a mile from my house.
When I took files there to have them printed (C-prints) they asked for
them to be sized at 305 ppi. I don't know the reason why for that either,
although I asked.
Their explanation was it "just worked better if you used an odd number"
and "305" was the odd number they wanted me to use.
Go figure.
