1. Re: live trace and thin annoying outlines
[scott] Jan 29, 2011 10:06 PM (in response to plutonak)The thin white lines are due to on-screen anti-aliasing. You can turn off anti-aliasing in the preferences. But really, they are on-screen only. If you print or save for web, they vanish.

2. Re: live trace and thin annoying outlines
Mylenium Jan 30, 2011 2:37 AM (in response to plutonak)As Scott already said, these issues usually only affect on-screen display. On the other hand, they may be "real" due to minute differences in the position data of the anchor points for adjacent shapes. In any case, the easiest way to verify it woul be to save it to a PDF and view that PDF in Acrobat with overprint preview. Even if you enable overprint preview in AI and the relevant object options, it's usually not as exact as Acrobat's.

3. Re: live trace and thin annoying outlines
plutonak Jan 30, 2011 3:22 AM (in response to Mylenium)thank you both for the explanations. I'll give a try to Adobe Reader but I usually use another pdf viewer which shows the thin outlines. I'm not quite sure if the latter can handle the mentionned artefacts.
I should also say that this is intended to be used for an e-book, that should be read on-screen [I just tried in my pdf viewer and it looks ugly]. Accordingly, I'd like to avoid this: what do you think of point 2 in my original post? Thanks again

Wade_Zimmerman Jan 30, 2011 8:11 AM (in response to plutonak)Select All
then go to Effects>Stylize>Feather
set the feather at either 1,2 or 3 points which ever works.
That should give you a very nice pretty rendition.

I do not have the feather option but "glowing edge" instead. Is this what you meant? I tried it but this is not working at all. Fillcolors are lost and everything gets pixelized, I think.

Wade_Zimmerman Jan 30, 2011 9:01 AM (in response to Wade_Zimmerman)After you give it the feather, maybe 1 pixel would be good enough, then turn off the effect and see if the artifact is gone on screen.

8. Re: live trace and thin annoying outlines
plutonak Jan 30, 2011 11:51 AM (in response to Wade_Zimmerman)thanks, I missed that stylize (I was using the other one). Anyway, I do not get nice results. Is the attached picture a personal try? It looks nice but I do not get anything similar. When I select the anchors and then follow the procedure, I get blury (pixelized?) white outlines and I do not really understand the "then turn off the effect"? I think it is important to say that I want something purely vectorial. I'll try to investigate further.

9. Re: live trace and thin annoying outlines
[scott] Jan 30, 2011 1:29 PM (in response to plutonak)A real easy fix for it on screen is to simply place a rectangle behind the trace and fill it with a base color.
