Adobe Creative Suite 5 Printing Guide 76
•Shape Builder Tool: Drag across multiple objects to combine them;
similar to Pathnder’s “Unite” feature, except that the color of the
combined object is based on the rst object clicked.
•Align to Pixel Grid: To ensure that vertical and horizontal segments of
vector paths are rendered crisply on the Web (rather than being
soened by anti-aliasing), this new option adjusts these straight-line
segments, aligning them to the pixel grid.
•Path Joining Enhancements: Rather than trying to select the end-
points of paths you wish to join, you can now just select the object
you wish to close (or open objects you wish to join), and choose
Object > Path > Join. Illustrator will join the two closest endpoints.
•“Select Behind” Keyboard Shortcut: Command-click (PC: Ctrl-click)
to drill down through stacking order (as you can in InDesign).
•Bristle Brushes: is new brush type creates watercolor-like strokes
that use transparent components to accomplish so color appear-
ances. Heavy use of Bristle brushes can create complex artwork that
may present some challenges in imaging. If you are using a workow
based on the Adobe PDF Print Engine, you should have lile or no
diculty processing an Illustrator le containing a reasonable amount
of Bristle Brush content. If you are using an older PostScript-based
workow, however, you may encounter long processing times, espe-
cially if trapping is required. You may have to simplify some illustra-
tions, or rasterize content by selecting the Bristle Brush strokes and
choosing Object > Rasterize. Of course, if the le contains content that
must render as a spot color, this will convert the content to the current
document color mode (CMYK or RGB, depending on how the docu-
ment is set up, and this may be undesirable. Consider advising your
customers to be cautious when using this new feature; encourage
them to submit test les so that you can determine the best method
for handling the content.
Artwork Created With Bristle Brushes
Bristle brushes can easily create naturalistic artwork, resembling watercolor art (le). Like
other brushes, Bristle Brush eects are appearances applied to strokes (shown center, in
Outline mode). If Bristle Brush appearances are expanded, they may create large numbers of
complex objects with blending mode and transparency aributes (far right, in Outline
mode). While there is no advantage to expanding such artwork, it gives you an idea of the
complexity of the outgoing print stream.
Bristle Brush Alert
When you save an Illustrator le containing more than 30 Bristle Brush strokes (no maer
how simple they might be), you will receive an alert that implies that you may encounter
some issues if you aempt to image the le in an older workow.

Although these features are not new to Illustrator CS5, they are worth
mentioning since you are often required to edit or correct customer
artwork.
•Separations Preview: View individual inks in color, as well as over-
print eects. Selectively show and hide individual spot and process
colors to preview color separations on screen, so you can quickly and
easily identify potential printing problems early in a job.
•Bleed Support: You can dene a bleed zone of any width for a docu-
ment, as in InDesign. Bleed values can be dierent on each side, and
are applied to all artboards in the document. You cannot control bleed
aributes on a per-artboard basis.
