Document raster effects settings
Whenever you apply a raster effect such as Blur or Sketch, Illustrator uses
the document's raster effects settings to determine the resolution of the re-
sulting image. These settings have a large impact on the resulting artwork;
therefore, it's important to check the document raster effects settings before
you start working with filters and effects and, more importantly, before you
export or print your artwork. You set rasterization options in the Document
Raster Effects Settings dialog box (Effect > Document Raster Effects Settings).
Document Raster Effects Settings will be set correctly when you choose the
appropriate New Document profile for any particular medium.

Filters and effects
Many commands for changing the look of objects are available in both the Filter
and Effect menus. For example, all of the commands in the Filter > Artistic
submenu are also listed in the Effect > Artistic submenu. However, filters and
effects result in different outcomes, so it's important to understand the differ-
ence in their use. Effects are live, which means you can apply an effect to an
object and then continue to modify the effect's options or remove the effect
using the Appearance panel. Effects are nondestructive—they don't change the
underlying object. Once you apply an effect to an object, the Appearance panel
lists the effect and enables you to edit, move, duplicate, or delete the effect, or
save it as part of a graphic style.
Filters, on the other hand, change the underlying object, and the changes can't
be modified or removed after the filter is applied. One advantage to reshaping
an object with a filter is that you have immediate access to the new or modified
anchor points created by the process. (An effect must be expanded before you
have access to the new points.)
Note that when you apply filters or effects to linked bitmap images, the images
will be unlinked and become embedded in the document.
