The problem I see with this rack is there is no protection for the paper surface or keeping the rolls from coming unwound.
Not sure which rack you mean.
With mine, I use the clips supplied by Epson that snap around the paper to hold it. Some of the papers go in their plastic sleeves.
I hate taking paper off the spindles to store, and putting back on. That is usually when they get damaged. Plus I have a bad shoulder.
I only use about 5 of the 8 spindles I have right now.
