Thanks for the response.
So you dust the paper before printing? Do you think that there are flecks of coating on the paper left from manufacturing?
Unfortunately, the flecking isn't minor in my case - the prints are unusable.
I can't speak to Mediastreet's products directly, but many of the fine art type papers exhibit minor flecking and / or have small particles of coating or fiber residue on the surface. Since I have started to dust each sheet with a soft bristle drafting brush, I have not had this problem.
Hope that helps,
