Illustrator vector aliasing


Question

How can I make my vector graphics anti-aliased in illustrator? My paths always turn out jagged. Is there an option like in Adobe Fireworks to smoothen[remove the jaged edges] my paths?

Accepted Answer

In Edit > Preferences > General there is an option that toggles Anti-Aliasing for art as it is displayed on screen while you work.

Under Effect > Document Raster Effect Settings there is a checkbox for Anti-Aliasing that controls to some degree the outcome of the file once it is saved to a non-vector format (ie. jpg, gif, png).

Depending on which file type you save to there are often more options that can affect the appearance of jagged lines in your art. What you are saving can influence how you should use these settings, as you may want to do things that may seem counter intuitive. Small type for example may need no or very little anti-aliasing or it will become muddy. Also take into consideration the PPI of the file. Low resolution images will appear have jagged edges even with anti-aliasing—the human eye can detect up to 150 ppi, at 72 ppi the pixels will not resolve at a normal viewing distance.

If you are having aliasing problems in Illustrator CC 2015, ⌘+E toggles between GPU and CPU previewing. CPU's anti-aliasing is 1000% better.
