As a Moab Master I'm asked every so often how our studio handles paper storage. We're constantly testing papers for ones that meet our high standards (another reason we love Moab papers!). Boxed sheet papers are obviously no problem, so long as you have room and shelves to stack them and the humidity is not too high. But roll paper presents different challenges.
For years, as our fine art printing grew, we faced an increasing mess. Some of our roll papers we put back into the boxes they came in, while others we slipped into their plastic bags, and still others stood bare, ready to be used. As the variety of rolled paper types increased we sometimes got confused about which papers were which. We wasted time sorting through boxes to find the right paper and then wasted more time unboxing and re-boxing them. As a result, we also had a fair amount of wrinkled, torn, bent and otherwise damaged paper, which is a big dent in one's pocketbook.
We finally tackled our roll paper storage problem once and for all. I'm not suggesting that our solution will work for you, but it sure works for us. Modify to suit your needs.
We had a narrow closet that we already used for our pathetic version of roll paper storage. When I couldn't take it any longer, I cleared out all the papers and created the storage solution you see here.
