I used to coat all my sheet the day before and print the day after for a
big work I did ( large 20x24 print). I dry them fully and let keep them
dry all night before humidyfing them the day after and print. I find that
with my system , longer time than 24 hours arent' good for the print . But
my system to keep them dry wasn't as perfect as it need.
