Curly Cover

Hey all,

I run a small 4 color ryobi and have been having issues with cover stock. The Last Month or so The paper I get from the distributer every other sheet has a different curl to it (one up and one down)We use all kinds of sizes and weight and Most of them have it. I have seen it in on matte, gloss,and silk. The weird thing is that I have seen it in two differant mill suppliers. The paper people say we are the only one having this problem. I find that hard to believe. Anybody Else see this? Or have an explanation

 

I have seen this before, we tracked it back to the paper being multi roll sheeted. when rolls of paper are unwinding in different directions the natural curl tends be different. It wasn't always a problem but every so often.....
