How do you avoid visible lines in gradients, made with Photoshop, and make a smoother transition?
I've tried adding gaussian blur and noise, with Noise Filter, but the problem remains.

Blurring does more damage than good.

You'd be surprised how much of it disappears when it's properly printed. If you're doing colour laser test prints they a;lways look like shit.
I usually multiply a noise layer over a solid-transparent gradient selection. Works ok. It also depends on the colour choice - if find cyans/greens to be a pain in the arse.

noise + .1 gaussian blur on a mask

Does anyone know if this is also an issue related to 8 bit vs. 16 bit settings?

It's for the web, not for print.
Seemingly no matter how I add noise and/or blur, it messes up. Adding another colorstop might do the trick, but so far that hasn't worked out either.

This is a real pain. None of the solutions suggested in the other pv threads do the trick.
Dither is on and so is transparency, and mode is set to normal...
Is the approach wrong - shouldn't I use Photoshop for this particular job?

Detritus:
Not too bad. I notice it, but something as subtle as that would work out just fine. Do you have any pointers on how to achieve something similar with color (rgb)?

Not really, I was trying to work out whether it might be an OS/Monitor derived problem - but I guess if you don't see massive banding there or in other gradients outwith Photoshop, then the problem's probably within PS itself. Sorry, not much use, I know.

Have you monkeyed around with the Color Settings dialog under the Edit menu?

Is your grad running perfectly vertically? If so it will be nice like Detritus'. If you angled it freehand though and its a twaddle off the perp it gives out all sorts of monkey maths that knits crazy banding on the render.
- in Photoshop? I'd expect any manual transforms to increase the blur, and thereby reduce the banding in a gradient?detritus
- If you run a grad at like 90.5º or so it bands like crazy. Anyway, shut up, I dont know what I'm talkin about.Spookyhome

Could be your graphics card just isn't up to scratch?

Banding in gradients is a screen problem.
If you don't own an expensive monitor you will get banding and depending the model it gets better or worse. For example in my case I can see the banding and in the lighter parts I can see here and there some very light pink hues.
At my mate's Eizo screen (he spend something around 2500Euros on it - ouch!) it is smooth with not banding at all.
Actually drawing a gradient in Photoshop and setting it full screen is the best way to test if a monitor is good enough for photo manipulation and dtp.- I've got a cheap-ass Dell, with no banding, so no dice there, I'm afraid.detritus

- turn on those three check boxes in the "color managment policies" areasikma
- they won't solve your grad problem but they should be turned onsikma
- What ever you say. :-)doctor
- yes, they are an utter delight when you're opening a large amount of files...hit 'return' like 15 billion times

Drop res to 240 when printing!

Since my big Behemoth screen died before Xmas I've been using some cheap arse flat screen by Formac which I had to rush out and buy in an emergency. It was less than £100. It doesn't show any banding, so I don't think monitor quality is the ultimate answer to the banding probalo.

Yah, most modern computers should be able to handle a colour gradient adequately (!).
Um.. I'd try messing with the settings.if I were you. Make a note of the above.. or, just keep that graphic (!) .. and try changing the RGB setting, to see if it makes any difference. I'm not a MacHead though, so beyond trying that and checking your OS's colour depth, I'm at a loss to offer any useful suggestions.

any chance you can screenshot it, so we can see how extreme it is?
