I have bad news for you.
The factory who makes the photopaper for us has announced last year that they cannot produce on 320g anymore because the base is not made by the papermill anymore.
We have already contacted the paper makers (base paper) and are trying to resolve the issue but they speak in order volumes where even fotoimpex has to stretch the wings.
The last word is not yet spoken but I am afraid that we wil have to go down to 280g from may on.
Let me know if you want to stock up because this is the last week where we can actually place orders for museum weight which get confirmed.
Regards from Berlin,
