If you're doing big prints, one way to dry is to attach them to big sheets of foamcore using binder clips. Behold...
http://www.officedepot.com/ddSKU.do?level=...pplies-_-838056Just lean them up against a wall for 3 to 7 days for RC papers, 2 or 3 days for everything else. If you're careful the clips act as spacers between the foamcore sheets so you can lean 3 or 4 foam+prints combos up against each other this way. Two clips at the top is all you need, one is not enough because the print can slip dangerously sideways if somebody picks the thing up at an angle. The clips will dimple the prints so add an inch or two to the prints you plan to dry this way. Paper and foamcore can be reused indefinitely, it's a good investment.
If you want you can cover the print with a big sheets of cheap roll paper while drying, if you have a dusty environment that's a good idea.
Once your prints are dry you can store 4 to 6 prints on top of each other this way, cover the top print with a sheet of paper or second piece of foamcore and clamp the cover at the bottom of the foamcore as well. Put maybe three clips at the top to hold the extra weight and guarantee no prints can slide sideways relative to each other. Having three clips makes it easier to remove just one print while still in the vertical position...hard to explain but easy to do when you get to it. Write down the names of the prints in the pile on the foamcore so you don't have to go rifling through the stack to find the one you want.
