Yes. Our PDF templates can be opened in Adobe Illustrator. They are treated as an import, which means you will be presented with a few options when importing. Depending on the version of Illustrator you're using, you will see different variations. We'll cover the main contents you need to be aware of in order to select the appropriate options.
1) Pages – If you are given the option to select All pages at once, do so. This will give you the entire template file at once. Otherwise, if you are only able to import 1 page at a time, you may need to open the template multiple times (once per page) and then copy over all parts of the template into a single AI file.
2) Import PDF pages as links – This step is optional. But if you're given this option (will appear as a checkbox), we recommend selecting it. This will preserve our fonts and font styling so that the rendered template appears as intended. It will provide the most legible experience. However, you will not be able to interact with individual layers within our template. If you change your mind after importing, you can embed the template pages. If you are not given this option open opening the template, Illustrator will most likely convert fonts to outlines instead to preserve appearance.
3) Color profile – Most importantly, if you are prompted to select CMYK or RGB, select CMYK. On any print file, CMYK will provide the best color for printing. RGB is intended only for viewing designs on digital screens.
