ooops, forgot to attache the image - here it is. As can bee seen there's a kind of dimpled effect around the shape lines. It's almost as though the pattern was not created with smooth brush lines. I'm seeing the effect from patterns I've made using photoshop shapes and also from store bought patterns. So it could be a photoshop brush problem/shape problem. When you look at the patterns in photoshop though they look fine.
Very frustrating.
