I picked up an older roll of Canon Heavyweight Satin (300gsm) on sale. It's a 16" roll. The prints look very nice, but I have not been able to get rid of the curl. I have even tried leaving them wrapped in my D-Roller overnight, after a few hours in the D-Roller did not do the job, and a day or two later they start to curl again.
Is this a problem with the older Heavyweight Satin? Any suggestions?
Thanks.
Terry.
