loading a noise filter into illustrator actually won't help. I've tried that actually in Photoshop for 3d renders that have banding in them. You can't really fix it after the banding is already there.
The noise option in Photoshop within the layer effect doesn't add noise to the gradient. It adds it to the definition of the gradient. So it blends each value with the next using a noise pattern. That's what hides the edge. Just adding noise would only put noise on top of the edge that's already there. You might mute the problem a little, but it's still there.
Add grain? I'm not quite sure what you mean?
Export to Photoshop? Yes, that's kind of what I would do. Although, you have to actually create it in photoshop, and import. Exporting it there's not much you can do once the banding is there. But I'm actually asking this question for everyone that works here so I can learn and share (assuming there's something new to be learned about this). They don't want to do that. I hate banding personally, so That is actually how I do it.
RIP with smooth shades? I can try some different color methods, but I'm not sure what that means. I'm printing directly to a canon iPF8300 (that's the 12 color version). I'm not using any separate server. We're not quite that fancy.
Is Illustrator's gradient actually defined mathematically and rebuilding depending on the ouput then? I notice the gradient actually looks pretty darn good on my monitor. I have to Really try to get any banding. But I have higher quality monitors. (I just got lucky) But it's still there.
Even if it's "the printer's fault" I'd still like to know if there's an option to add further blending. I'll have to do some tests adjusting resolution and rasterizing it. If Illustrator is doing that by default, but at a resolution that's too high, then the printer Might be seeing that as a solid band of one color? Yeah, that's a question because I'm not sure if I've just said something that sounds magical or intelligent.
I'd like to know how the gradient works in Illustrator in order to further understand the problem. Using the gradient tool gets better results than creating a color blend, so it Has to be doing some blending of some sort. I'd just like to know how to better control it. I'm Really surprised so many people haven't noticed banding before.
Just out of curiousity, do this: Create a box and add a gradient from black to 89% black (CMYK document). Are you seeing banding? Does it print out that way? I answer yes to Both of those questions. In photoshop create the same thing, only don't use a gradient fill. Use a Gradient Fill adjustment layer and check the box that says "Dither". I was saying "noise" before, but now I realize that's in AfterEffect. In AE you can control the amount of blending between bands. It's not an on/off situation.
Anyway, dither checked on, banding gone? That's what I get. And that's what I was hoping to replicate in Illustrator.
