personally I am happy to see the hanging rack working out. I'm new to poster printing and don't have a rack. I have everything for t-shirts though. I'm going to put together a clothes line and string my binder clips.
replicant - the clips do indeed work, but as others have pointed out they are the slowest part of the printing process, and if I was printing alone I don't think they would work. With space to hang only 27 prints at a time, it is taking a few days to get thru the planned edition size for this design. I hate having to stop after only about 15 min of printing because we are out of space!
I'm puttering away on illustrations for my next prints. They are multi-color designs, and I want to get some sort of rack implemented before the ink starts flying on them. Got a quote from Gran Adell, looks like it would be around $700 to get their 40 tray easy ship rack out here. Now I gotta crunch the numbers on labor/wood to see if building my own would be cheaper.
