Hi, thanks for the responses and suggestions.

I've found that ramping up the contrast on what appears to be a clean b&w image actually shows up additional speckles and marks on patterns I've bought or created myself (even when I was careful to produce clean straight lines) . So it's possible to a certain degree to fill these bits with white to get rid of them. But even so the lines still don't show as 'clean' when used for a bump map in DS. I've tried creating a shape using the pen tool and also using a basic brush. Whatever I try I still get some of the same effect.

I'm thinking now maybe it's more of a question for the photoshop forum...
