The sheets of 17x22 Eposn Exhibition Fiber I used to get were absolutely flat, both out of the box and after printing. Both of the last 2 boxes I bought have had a significant lack of flatness, the first general waviness and the second not su much but significant curl edge along the long side, about 1/4". Both these boxes are the new black packaging while all the "good" boxes were the old white packaging. Has anyone else experienced this? I wonder if Epson changed it supplier
