First, we will create a new document and draw a circle. Then we will use the Pattern Options feature to generate the pattern used in the post image above.
- Start a new document. In the example, I used a 2000 x 2000 px x 72 res document.
- Set the Fill color of your choice, set the Stroke to null and draw a circle of any size on the canvas with the Ellipse tool. In the example, I drew a gray colored 50 pixel circle.
I like to work with whites and shades of gray. In this way, I can concentrate on the pattern and not be influenced by the colors. - From the menu, click Object - Pattern - Make (see screenshot) to open the Pattern Options dialog box (see screenshot).
- Give your new pattern a name such as "Simple Circles".
Let's add an empty space between the circles that is the same 50 px as our circle. To do this, we need to use the Size Tile to Art option (see screenshot). - Check the box next to Size Tile to Art.
- Set the H and V Spacing to 50 px each.
- Keep the other default settings.
- From the Options bar, click Done (see screenshot). This will close the dialog box and our pattern. But it is saved to the Swatches panel (see screenshot).
- Delete the original circle.
- Open the Pattern Options dialog box again by double-clicking on our swatch in the Swatches panel.
We can create a custom swatch library where we can save the swatch that we created. Then, when we are ready to use this swatch, we just need to open the custom library. Let's remove all of the default swatches from the Swatches panel and keep just our own swatch.
- Select all the swatches except our swatch. Drag them to the Trash icon.
- Open the Swatches panel menu and choose Save Swatch Library as AI (see screenshot).
- In the Finder window, give the swatch library a name and click Save.
- From the Swatches panel menu, click Window - Swatch Library - Other Libraries.
- In the Finder window, navigate to Library - Application Support - Adobe - Adobe Illustrator CS6 - en_US - Swatches - YourSwatchLibrary.ai. (This path may be different depending on your version of Illustrator and your operating system.)
- Select your library file and click Open.
