Adobe Illustrator CS4

Multiple artboards
Create files containing up to 100 artboards of varying sizes and display them any way you want — overlapping, side by side, or stacked. Save, export, and print artboards independently or together. Save a selected range or all artboards as a multipage PDF file.

Transparency in gradients
Define the opacity of any individual color stop in a gradient. Reveal underlying objects and images, and create rich color and texture mixes using multiple layers, knockouts, and cover-up fades.

In-panel appearance editing
Edit object characteristics directly in the Appearance panel, eliminating the need to open fill, stroke, or effects panels. Work with shared attributes and control display for faster rendering.

Blob Brush tool
Sketch with a brush that generates a single clean vector shape, even when strokes overlap. Draw naturally, using the Blob Brush tool together with the Eraser and Smooth tools.

Refined graphic styles
Combine styles for unique effects and increased efficiency, and apply styles without disturbing an object's existing appearance. Enjoy new thumbnail previews and an expanded library of prebuilt styles.

Gradients exposed
Interact with gradients right on your object. Set gradient angle, position, and elliptical dimensions. Add and edit colors using sliders — all with immediate feedback where you work.

Clipping masks demystified
Work with masks more easily by viewing only the clipped area of your objects during editing. Take advantage of Isolation Mode, and use Edit Clipping Path for even more control.

Integration and delivery
Collaborate with your team, work across products, and deliver almost anywhere thanks to integrated tools and extensive format support. Confidently design for print, interactive experiences, motion effects, and more.

Separations Preview
Avoid color output surprises such as unexpected spot colors, unwanted overprinting, overprints that don't overprint, white overprinting, and CMYK blacks in text and placed files.

Enhanced user experience
Stay in the creative groove thanks to interface improvements that include on-object controls. Interact with tools smoothly, and increase your efficiency using new timesaving features and shortcuts.
