Bill,
I also would like to know how each stores his paper and from what
supplier they get it from. The relative
humidity of the storage area, affecting RH of the paper at the time of
first coating, will also affect the results. As to the drying temp and
time, they will both change the effects of coating. I was able to
eliminate streaking on some papers early in my coating days by adjusting
the front and backside drying times and temps when using a blow dryer.
