Re: brush vs tray size for gum
ahem, some time ago I remarked on the list that I thought humidity had more of an effect on PT/PD than seemed to be mentioned in the literature...then I speculated that perhaps this might be true of other processes........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................back to my closet—I may be safer there if that spontaneous thingy should try to attack me again.

This thought came to me after reading Keith's observation that a damp paper clears better for him than a drier paper; I thought, well, maybe that's why I was able to print tricolors on unsized paper without stain for years (although I can no longer find a paper that will do that) because I was printing in a very humid environment. And other differences may also be related to this as well; who knows? Katharine
