Thanks for the link. This is what the author states,

When I work with images that show this kind of banding, I change my workflow. Instead of converting the edited RAW file to JPG, I convert to 16-bit TIFF instead, and then do the retouching. Only at the final stage, do I convert to JPG for web use, or for uploading to a lab. In this way, I work with a 16-bit file for as long as possible.

Which is exactly what I do. And just merely adding say 20pixels gaussian blur to the 16-bit TIFF image immediately shows colour banding and posterization. What possibly could I have done wrong?
