Re: gum question
Thanks, Judy. I'll try that. If you have that written in the
Journal, I'll go back and look at the times. If the longer room temp
soak does the shrinking without raising the nap of the paper, that
would sure be worth trying.

indistinct, anyway, that the edges weren't clearly defined from the

It occurs to me to wonder if .... since you're dancing around
minimum pre-shrink, minimum pre-stress, or "virginity," so to speak,
it might make a difference if the pre-shrink wasn't HOT. A while
back I tested a looong preshrink in room temp water vs. the HOT
short preshrink that's the norm.
I found that the long room-temp soak gave the same amount of shrink
that the short hot soak did... I don't remember the times, tho I
could probably find them in Post-Factory, but it occurs to me to
wonder if the room temp soak might "raise the nap" or rough up the
paper less than the hot.
Of course you seem to be doing OK the way you're doing it, & no need
to fix it, if it ain't broke, but I mention the thought, should a
snag arise.
