Is it really impossible to have gradient without banding?

I am struggling to create a gradient without banding. I have watched all the videos on YT and tried: Bluring all kinds, Noise, Dither,bit depth, Brush and doing the gradient in Illustrator.

Everything fails and I can always see the banding.

The background color I use behind the image: 050b3c

Noise and dither usually yield quite good results. There’s a couple of things that may make “banding” more apparent:

  • “start” and “stop” colors
  • gradient size (banding becomes more apparent when “start” and
    “stop” points are getting farther from each other—gradient have to be “projected” on more samples with the constant number of available brightness values),
  • miscallibrated/poor quality monitor (have you tried to view your gradients on different monitors?),
  • reduced “per-channel” color resolution in system settings (seems unlikely nowadays since most systems use 32 bps settings, but still a possibility),
  • “wild” video card gamma settings (e.g. in “video card control panel” or gamme loader like Adobe Gamma Loader),
  • too “agressive” monitor profile (again view-on-other-monitors test should provide some hints about it),
  • reduced bit depth of an image.

Also it would be useful to know what your target device is. There’s a difference how much you can “spread” your gradient whether you’re targeting print (what kind of print also matters e.g.: screens like AM, pseudo-stochastic, stochastic) computer monitors or mobile devices displays. It also makes difference then wether you use raster graphics or vector graphics.

Bottom line is: this is quite complex subject :).
