I think that if you used Fourier analysis, you could identify the frequency generally associated with the dot size, and delete the signal in that band. This can also be used to achieve excellent reduction of the Moiré effect:

This has the advantage of also not reducing the image quality as badly as when you try to blur the patterns away spatially.
