There are a few things you can do to help save a vector file in Photoshop. The first is to make sure that the file is properly named. If it isn’t, Photoshop will automatically fill in the name for you. Next, make sure that all of the layers are set to " Luminosity" or " Opacity." This will help keep the file organized and easy to work with. Finally, be sure to save the file as a PDF or JPEG.
