slider, to specify the range by which the brush characteristic can vary. For each stroke, 
Random uses any value between that in the text box for the brush characteristic plus or 
minus the Variation value. 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.

Choose Pressure (if you will use the brush with a graphics tablet) to use a value deter-

mined by the pressure of your stylus. When you choose Pressure, you also need to enter 
a value in the Variation text box, or use the Variation slider. Pressure uses the value in 
the text box for the brush characteristic minus the Variation value for the lightest tablet 
pressure. It uses the value in the text box for the brush characteristic plus the Variation 
value for the heaviest pressure. 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.

You use artwork from an illustration to define the scatter brush.You can change the size, 
spacing, scatter pattern, and rotation of objects painted on a path with scatter brushes.

1 Select the artwork to be used as a scatter brush. 

2 Click the New Brush button   in the Brushes palette, or choose New Brush from the 
palette menu. Select New Scatter Brush and click OK.

3 In the Name text box, enter a name for the brush (up to 30 characters).

4 Drag each Minimum slider or enter a value in each leftmost text box for the brush’s size, 
spacing, scattering, and angle of rotation:

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.

5 From each pop-up menu, choose the way in which you want to control variations in the 
size, spacing, scattering, and rotation:

Choose Fixed to use the value in the associated text box. For example, when the Scatter 

value is 50%, Fixed always uses 50% to scatter objects along the path.

Choose Random to use a random value. When you choose Random, you also need to 

enter a value in the rightmost text box, or use the Maximum slider, to specify the range 
by which the brush characteristic can vary. For each stroke, Random uses any value 
between the Minimum and the Maximum value. For example, when the Minimum 
value is 50% and the Maximum value is 100% for Size, the objects’ sizes can be 50%, or 
100%, or any size in between. 

Choose Pressure (if you will use the brush with a graphics tablet) to use a value deter-
