When exporting to 24 bit (!) JPEG or PNG, I would like to add some noise/dithering to gradients - is this possible?
Here is why: When gradients are too clean, stripes / banding may be visible when printing.

I just applied the solution recommended in another thread, and it seems to do the trick: Apply the Diffuse live effect, and clip the object with the desired shape.
It would be nice, though, if there was an easier way in Xara Designer.
Mike's solution above is better than diffuse as you can easily set the strength and density of the noise and no clipping is required.

Frances, I checked the noise effect as well, and in fact I use it somewhere in that illustration. However, for the gradient I believe that diffusion is the higher quality option, although a bit cumbersome.
How are you exporting your image? And at what color depth?

Hi-res 24bit JPEG with 100% quality.
Currently the target is a photo printer which works with sRGB color space (prints are developed). In the illustration there is a gradient taking up a major part of the page, and in tests with dye-sublimation printers (CMYO), I have seen ugly banding. Applying the diffuse filter makes the banding disappear.
