Core one PEI Sheet became bumpy after trying atemperature tower for ASA
So i wanted to do some filament calibration for some leftover stratasys ASA and when i remove the PEI plate, i noticed that the side of the sheet that was in contact with the heatbed became bumpy.
Both sides also got the bubbles.
Im not sure how visible the bumps in the image are
I used this upload for the tower (core one, standard nozzle, ASA): https://www.printables.com/model/39810-improved-all-in-one-temperature-and-bridging-tower/files
Anyway, is this expected to happen or did i do something wrong?

This is normal behavior for the adhesive film.
For ASA, I would recommend using a textured or satin printing plate.

how much does it affect adhesion of prints with pla, petg or abs?
also is there any information on prusas website that i didnt see?
on their printplate maintenance site where they list what materials work with what printplates, it just said use gluesticka

i just checked https://help.prusa3d.com/article/smooth-steel-sheet_196550 and it says its "Main attributes Ideal for printing PLA, HIPS, ABS/ASA, composite materials (metal/wood)."
How is it ideal if it makes one side of the printplate unusable?

A small counterexample:
Yesterday, I “destroyed” my PEI printing plate. My PETG print was so good in the first layer that the film detached from the carrier layer. Normally, I remove the printed part when it has cooled down a little. Unfortunately, in the case described, it was cold and I forgot to warm it up beforehand.
As I said, the bubbles are normal. They will disappear again over time.
A release agent to make it easier to remove the printed part is the best choice.
In my opinion.
RE:
Prusa says not to worry... Page 52 of the 3D Printing Handbook for the Core One, which describes the smooth PEI sheet:
If you notice small bubbles appearing beneath the PEI layer on the flexible print sheet, just flip it over and print on the other side. After a few days or weeks, the bubbles should disappear. The bubbles have no effect on the print quality
Edit: So the user needs a few more of these plates, unless two prints (on two sides) every "few days or weeks" are enough...
