Painting
• Rotation Creates a brush that varies in angle, roundness, or diameter based on how the drawing stylus pen tip is
rotated. This option is most useful when used to control the angle of calligraphic brushes, especially when you’re using
the brush like a flat pen. It is available only if you have a graphics tablet that can detect this type of rotation.
Colorization options for scatter, art, and pattern brushes
The colors that a scatter, art, or pattern brush paints depend on the current stroke color and the colorization method
of the brush. To set the colorization method, select one of the following options in the Brush Options dialog box:
None Displays colors as they appear in the brush in the Brushes panel. Choose None to keep a brush the same colors
as in the Brushes panel.
Tints Displays the brush stroke in tints of the stroke color. Portions of the art that are black become the stroke color,
portions that aren’t black become tints of the stroke color, and white remains white. If you use a spot color as the
stroke, Tints generates tints of the spot color. Choose Tints for brushes that are in black and white, or when you want
to paint a brush stroke with a spot color.
Tints And Shades Displays the brush stroke in tints and shades of the stroke color. Tints and Shades maintains black
and white, and everything between becomes a blend from black to white through the stroke color. Because black is
added you may not be able to print to a single plate when using Tints and Shades with a spot color. Choose Tints and
Shades for brushes that are in grayscale.
Hue Shift Uses the key color in the brush artwork, as shown in the Key Color box. (By default, the key color is the most
prominent color in the art.) Everything in the brush artwork that is the key color becomes the stroke color. Other
colors in the brush artwork become colors related to the stroke color. Hue Shift maintains black, white, and gray.
Choose Hue Shift for brushes that use multiple colors. To change the key color, click the Key Color eyedropper, move
the eyedropper to the preview in the dialog box, and click the color you want to use as the key color. The color in the
Key Color box changes. Click the eyedropper again to deselect it.
For information and samples about each choice, click Tips.
Scatter brush options
Size Controls the size of the objects.
Spacing Controls the amount of space between objects.
Scatter Controls how closely objects follow the path independently on each side of the path. The higher the value, the
farther the objects are from the path.
Rotation Controls the angle of rotation of the objects.
Rotation Relative To Sets the angle of rotation for scattered objects relative to the page or the path. For example, if you
select Page, at 0° of rotation, objects point to the top of the page. If you select Path, at 0° of rotation, objects are tangent
to the path.
The pop-up list to the right of each option lets you control variations in the shape of the brush. Select one of the
following options:
• Fixed Creates a brush with a fixed size, spacing, scattering, and rotation.
• Random Creates a brush with random variations in size, spacing, scattering, and rotation. Enter a value in the
Variation box to specify the range within which the brush characteristic can vary. For example, when the Diameter
value is 15 and the Variation value is 5, the diameter can be 10, or 20, or any value in between.
• Pressure Creates a brush that varies in angle, roundness, or diameter based on the pressure of a drawing stylus.
This option is available only if you have a graphics tablet. Enter a value in the rightmost box, or use the Maximum
