Everything else being equal a variation in the moisture content of the paper might make a difference (more so for an uncoated paper?). I don't have any objective reason to say this, just an impression that there is a difference. It might be that it takes a large difference in humidity to matter. I do experience such changes since the climate control in the building where I work is long on climate and short on control. I can measure the humidity of the room but not the moisture in the paper. I would expect a change in dot gain that might well be different for each of the CMYK inks. The moisture content of the paper would increase with an increase in humidity but how much and how fast? If the paper is stored in a plastic bag, the moisture content would change slowly if at all but what was the moisture when inserted in the bag? I wonder if a wood moisture meter could be used on paper? My immediate reaction to this is NO NO, not another instrument, NO NO, not more tests!
