Gradient Fill problem

Update to 8.1v1 and then in the Color Settings, make sure Gradient settings within Rendering Intent are set to Perceptual or Relative Colorimetric. There is also a setting in the RIP to smooth gradients.

 

many little bugs resolved in the 8.1v1... 8.0v3 had a file corruption/loss bug that would randomly corrupt/delete files.

 

The rendering intent is not the problem. In fact 'Spot' is a far better choice of rendering intent for gradients than any of the others. Neither does if have to do with any sort of software bug. Unless you want to call poorly engineered software a bug.

It has to do with the algorithm you've chosen for dealing with blends.

You need to select a higher setting for the blend handling. If you use the bottom setting, 'Normal' or something like that, you'll get all manner of weird interpretations of gradients. Especially if they should happen to pass through or to white. Just up the ante to "Enhanced" for blends. It won't make any sort of measurable difference in the time it takes to do anything but your gradients will look like they're supposed to look.

 

Check your gradient colors. Are both ends spot color?
Have you tried converting them to RGB or CMYK?
