Creating Patterns with Adobe Illustrator CS6 is extremely easy, and so is exporting the pattern to be used on a Web page.
These are the 4 simple steps you have to follow:
- Create your pattern using the new Pattern Creation Tools in Adobe Illustrator CS6.
- Drag the Pattern Swatch from the Swatches Panel onto the artboard, and check out the Pattern Tile Bounds (blue outline).
- Select the Artboard Tool, press the Shift Key and start drawing an Artboard that matches the size of the Pattern Tile Bounds
- With the Artboard selected, choose File > Save for Web... and choose your preferred export oprions for PNG, JPG, or GIF.
