Allow to add dithering to gradients to reduce banding / improve quality
We have banding when printing gradients from exported TIFF-files.
I have to open them in Photoshop, search a way to select areas with gradients and apply noise in channels needed.
I can apply Grain effect to gradients where I need, but this makes everything run very slow.
What if you add dithering as an option to gradient swatch? or to fill?
So it could be displayed in screen space, applied to current level of zoom, and would export as raster images as well? without slowing down?

J'ai le même souci et c'est vraiment pénible. Et je trouve que c'est encore pire avec la version 26.0.1.
Gradients have always been bad in Illustrator. If I need accurate gradients, I sometimes redo them in a rasterized file in Photoshop, which gives much better results,. of course this is not exactly a solution for most cases.
It would be great to see more a higher quality gradient in future versions, because it's really a strange weakness for such a developed piece of software.
YES! Exactly! I have noticed an increased gradient banding on the latest update. :( It has not been this noticeable before. On all color modes as well. Has some setting changed with the update, that I can reset or change?
Please let us know when this is addressed.
For our large format graphics company, this can cost us a lot of time. (having to correct the banded gradients in Photoshop before output)
Illustrator is great! (let's keep it it that way)
What do you expect? :)
You have only 5 steps over this big distance, of course it's blocky. And it will print as such, until your RIP can add some noise to prevent banding.(Edited by admin)
Mac OS High Sierra, Version 10.13.1
Adobe Illustrator Version: 23.0
For this linear gradient, my middle value is (0,0,0,90) and my two end values are (0,0,0,95)
The rendering shows up very blocky and striped.
All other color options appear to be blending fine. But most combinations of the really dark blacks and greys show up blocky like this.
There is banding from black and white when I do a gradient and it does not matter what size the object is I am doing the gradient onto.
A nice smooth gradient is important without banding. I have seen this done on many items, not sure what they used, but the gradients were so smooth and flowing.
I then tested it with white that went to 50% grey and still banding.
Why is the quality of the gradient tool so terrible in illustrator?
Also, why is it so complicated to get the color you want from the library, or any color into the gradient tool? Can you make the gradient tool work like it does in photoshop? That is a nice user interface. Course that one also has quality issues.
I know exactly what Raster Effects settings do, thanks, lowering it down is not the way — I still have to remember boost it up, when exporting final images. If AI could have a display quality slider, as Indesign has, that would help a bit though.
