Before you send your artwork files to us, if you have imported (linked) any photos, logos or other files within your Adobe Illustrator file, you must either embed the image or provide the linked file to us along with your artwork.
If your linked image files are particularly large or complex, you may not wish to embed images within your Adobe Illustrator file. However, you must ensure you supply any images you’ve used with the artwork files you send to us. In this case, we suggest you use the “Package files” feature of Adobe Illustrator to ensure all linked artwork files are gathered together.
