Thx Mark, I'll try your tips :) !!

Yes, it's for printing. I have rendered it at 4000x3000 and it's the same.

I remember having gradient problems in Photoshop itself, you're right, I shouldn't be expecting a smooth gradient here ^^ The problem is, the difference between the grays makes it impossible to remove with my friend the Gaussian blur :P I'll try more filters, like you said.

Thx again,

Bala
