[Alt-photo] Re: wrinkles

[remko]

I see the same behaviour when drying my negatives (Agfa copy jet) 
between sheets of normal inkjet printing paper . so I introduced the 
blower as standard step in my workflow

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.

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...
