USING ADOBE ILLUSTRATOR CS4

Creating special effects

Crosshatch Preserves the details and features of the original image while adding texture and roughening the edges of

the colored areas in the image with simulated pencil hatching. The Strength option controls the number of hatching

passes (from 1 to 3).

Dark Strokes Paints dark areas of an image closer to black with short strokes, and paints lighter areas of the image with

long, white strokes.

Ink Outlines Redraws an image with fine narrow lines over the original details, in pen-and-ink style.

Spatter Replicates the effect of a spatter airbrush. Increasing the values of the options simplifies the overall effect.

Sprayed Strokes Repaints an image using its dominant colors with angled, sprayed strokes of color.

Sumi-e Paints an image in Japanese style as if with a wet brush full of black ink on rice paper. The effect is soft, blurry

edges with rich blacks.

Pixelate effects

The Pixelate effects are raster-based and use the document’s raster effects settings whenever you apply the effect to a

vector object.

Color Halftone Simulates the effect of using an enlarged halftone screen on each channel of the image. For each

channel, the effect divides the image into rectangles and replaces each rectangle with a circle. The circle size is

proportional to the brightness of the rectangle.

To use the effect, enter a value in pixels for the maximum radius of a halftone dot (from 4 to 127), and enter a screen-

angle value (the angle of the dot relative to the true horizontal) for one or more channels. For Grayscale images, use

only channel 1. For RGB images, use channels 1, 2, and 3, which correspond to the red, green, and blue channels. For

CMYK images, use all four channels, which correspond to the cyan, magenta, yellow, and black channels.

Crystallize Clumps colors into polygon shapes.

Mezzotint Converts an image to a random pattern of black-and-white areas, or of fully saturated colors in a color

image. To use the effect, choose a dot pattern from the Type pop-up menu in the Mezzotint dialog box.
