How to avoid banding effect on gradients?

TMarchev
Hello dreamstimers... i have many rejections by this reason:
Banding effect on gradients. Gradients and color transitions should be smooth, gentle and without color lines.
Any suggestions?
Thanks!

What I do is:

select the area.
contract the selection by one pixel
promote the selection to a layer
apply gaussian blur (6.00)
add 2% noise

usually that does it, and I can deselect and merge.

Sometimes I have play with it a little bit more.

The one reason of banding is that you don't have enough colors to get a smooth transition. I generally get banding on 8bit pictures. Altough I'm not an illustrator, as Therealdarla mentioned, I generally add some little noise in the banding area, it creates a nice transition and pouf! banding is gone :)

The action about i did talk here does it automatically (converts psd 8-bit to 16-bit and adds dither gradient for noise, then, pastes all layers in a new 8-bit file without the banding).

I think an action is usefull in this case, because you can working on a normal 8-bit psd (much less heavy), and later fixing the issue. Just with a couple of click, every time you need it. ;)
Be curious.
