Adobe Illustrator CS4 a comprehensive vector graphics environment with new transparency in gradients and multiple artboards that invite you to delve into more efficient ways to design.
Multiple artboards - Create files containing up to 100 artboards of varying sizes, 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.
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.
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.
Integration and delivery - Confidently design for print, interactive experiences, motion effects, and more. Collaborate with your team, work across products, and deliver almost anywhere thanks to integrated tools and extensive format support.
Enhanced user experience - Increase creativity thanks to interface improvements that include on-object controls. Interact with tools smoothly, and increase efficiency using new timesaving features and shortcuts.
In-panel appearance editing - Work with shared attributes and control display for faster rendering. Edit object characteristics directly in the Appearance panel, eliminating the need to open fill, stroke, or effects panels.
Refined graphic styles - Combine styles for unique effects and increased efficiency. Apply styles without disturbing an object's existing appearance. Enjoy new thumbnail previews and an expanded library of prebuilt styles.
Clipping masks demystified -Take advantage of Isolation Mode, and use Edit Clipping Path for even more control. Now it's easier to work with masks by viewing only the clipped area of your objects during editing.
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.
