Same media, same profile, two rolls, one doesn't print good

Hi, I have two rolls of Orafol 3164G bought around the same time, and I am printing with the right profile. One, 48", works great. The other, 52", sometimes prints great, sometimes leaves a lot of white spots, like this: What causes this and what can I do for fixing this problem?
