46 USING ADOBE ILLUSTRATOR CS4
Workspace
Pixel Preview mode (View > Pixel Preview) Approximates how your artwork will appear when it is rasterized and
viewed in a web browser.
Flattener Preview panel (Window > Flattener Preview) Highlights areas of the artwork that meet certain criteria for
flattening when saved or printed.
Soft-proofs Approximate how your document’s colors will appear on a particular type of monitor or output device.
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.
Device Central (File > Device Central) Lets you preview how your document will appear on a particular mobile phone
or device.

Rulers, grids, guides, and crop marks
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 show or hide rulers, choose View > Show Rulers or View > Hide Rulers.
• To show or hide artboard rulers, choose View > Show Artboard Rulers or View > Hide Artboard Rulers.
• 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.
