I was wondering if anyone that had thoughts on the longevity of Pictorico Ultra Premium UHP film digital negatives.

I've used Pictorico to make negatives for cyanotypes. The cyanotypes are exposed on a homemade vacuum lightbox with Phillips UV tube lights. Each exposure is 24 minutes long resulting in a fair amount of heat gain so the negatives are warm after each exposure.

I made Edition 1 over a year ago and now need to make another 5.
This work has 127 prints in total (so x5 is 635!!) so I need to be very methodical and factory like about how I print these.

Will I face any issues with the negative degrading when exposed to UV light for 24 minutes x 5 over a two hour period?

If you are interested, you can see some images of the work here:
