Creating Barcodes for Adobe Illustrator
First, download Barcode Producer.
Create your barcode in Barcode Producer, then either click the Illustrator button in the toolbar, or save your barcode as a vector EPS file and open it yourself in Illustrator. Once in Illustrator, there's nothing more to do – your barcode has been inserted as a vector graphic that you can place wherever you'd like.
You can also place the barcode directly in your working document by selecting File > Place in Illustrator and selecting the saved EPS file. It's probably best to click the embed button -- barcodes are small, so it won't take up much room in your Illustrator document.
Tip: The Illustrator button in Barcode Producer is merely a shortcut for saving the barcode as a vector EPS file and opening it in Illustrator.
