[Alt-photo] Re: wrinkles

I've experienced this with Pictorico stored between sheets of glassine.
Stopped using glassine and the problem went away.

Dear All,

Not the ones on my face...

I encountered this "event" the first time ever while teaching a workshop at
the Formulary this past week. I noticed on one student's prints these weird
wavy lines that looked like when you expose paper while still damp and it
unevenly is in contact with the negative. But that wasn't it. Finally a
student was smart enough to discover the issue (not me!). The tissue sheets
between pieces of inkpress were wrinkled, and so apparently when the
negative was fresh from the printer and placed in between these, using them
as interleaving sheets, the interleaving sheets puckered with the mild bit
of moisture and then in turn produced uneven dry marks on the negatives. The
following day I used a blow dryer on one sheet and it seemed to alleviate
some of the marks but not quite.

Has anyone experienced this??? Is it just that a thicker substrate like
Pictorico doesn't do it and this does? However, I have used Inkpress for a
few years now and never ever noticed it. I am just so surprised I have been
printing diginegs for 13 years and have never noticed this issue. However, I
do let my negs dry face up on the counter for a half hour and then put them
in plastic notebook sleeves. But last year I did store my negs in a box with
these sheets when I didn't have neg sleeves with me...

I'm a bit worried that this is particular to ink press.

Here's a URL to click on to see the phenomenon.
