Anti-aliasing
Gives vector objects a smoother on-screen appearance and provides a better idea of how vector artwork
will look when printed on a PostScript® printer. Anti-aliasing is helpful because screen resolution is relatively limited,
but vector artwork is often printed at a high resolution. To
turn on anti-aliasing, choose Edit > Preferences
> General
(Windows) or Illustrator > Preferences
> General (Mac
OS), select Anti-aliased Artwork, and click
OK.

Use rulers
Rulers help you accurately place and measure objects in the illustration window or in an artboard. The point where 0
appears on each ruler is called the ruler origin.
Document rulers appear at the top and left sides of the illustration window. The default ruler origin is located at the
lower-left corner of the illustration window.
Artboard rulers appear at the top and left sides of the active artboard. The default artboard ruler origin is located at the
lower-left corner of the artboard.

•
To change the ruler origin, move the pointer to the upper-left corner where the rulers intersect, and drag the pointer
to where you want the new ruler origin.
As you drag, a cross hair in the window and in the rulers indicates the changing ruler origin.
Note: Changing the ruler origin affects the tiling of patterns.
•
To restore the default ruler origin, double-click the upper-left corner where the rulers intersect.
