Brush options
You can specify different options for the different types of brushes. To change the options for a brush, double-click
the brush in the Brushes panel.
Scatter, Art, and Pattern brushes all have identical options for colorization.
Colorization options for 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.
Calligraphic brush options
Angle Determines the angle of rotation for the brush. Drag the arrowhead in the preview, or enter a value in the
Angle text box.
Roundness Determines roundness of the brush. Drag a black dot in the preview away from or toward the center,
or enter a value in the Roundness text box. The higher the value, the greater the roundness.
Diameter Determines the diameter of the brush. Use the Diameter slider, or enter a value in the Diameter text box.
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 angle, roundness, or diameter.
Random Creates a brush with random variations in angle, roundness, or diameter. Enter a value in the Variation text
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 most useful when used with Diameter. It is available only if you have a graphics tablet. Enter a value in the
Variation text box to specify how much more or less than the original value the brush characteristic will vary.
For example, when the Roundness value is 75% and the Variation value is 25%, the lightest stroke is 50% and the
heaviest stroke is 100%. The lighter the pressure, the more angular the brush
stroke.
