My vector strokes seems pixelized

[rafc71435511]

Hello,

I'm drawing with a caligraphic brush with pressure set to 3 using a wacom tablet and when i put a background color, lines seems to be pixelized. Why, are my strokes not vectors ?

Can't see anything wrong with that.

In the end you monitor displays your strokes as pixels.

Hi rafc

That looks like screen pixels to me so not really a problem, just a function of the output to screen. Did you try printing the art?

[rafc71435511]

I printed it. There is sligh white pixels between the black strokes and the red background 😕

[Michael Riordan]

That may be solved by selecting the black strokes and setting them to overprint. Window>Attributes> then check the boxes to overprint stroke and fill

It worked on the saved PDF art, no more white lines between the 2 colors. Thanks for this.

But Still very obvious and flashy on my illustrator. I followed every steps described in this tutorial, by the way : Adobe Illustrator Tutorial: How to Draw an Astrochimp - YouTube

It's an antialiasing issue that happens with 100K black.

Ok. So I just have to use another color with mu brush ?

What you need to do (or if you need to do anything at all) depends on a variety of details.

It has already been mentioned that overprinting helps.

In offset printing this usually isn't an issue.

And sometimes a different color helps as well.

Ichanged the color of the strokes, and overprinted the art before saving it. Here is the result : http://www.laluciolecreative.fr/wp-content/uploads/2017/11/Logo-Luciole.png

Pixelised 😕

The link does not work. Please post the image to the forum.

Sorry, it's quite visible on the site : http://www.laluciolecreative.fr/

What you've ran into here is the low resolution combined with an angle that often doesn't work well and Illustrator's weakness in rendering this stuff.

You might try if either exporting at double the resolution and then downscaling in Photoshop or opening the AI file in Photoshop and exporting from there is better.

Also there's a slight chance of a better result when you set the Antialiasing method to Supersamplig instead of Hinted.
