Raster images are digital designs made up of dots or pixels of ink that when together, make up your art. These types of artwork files print best at 300dpi (dots per inch) to make sure your stickers and labels print with the high quality design you created.

While raster images work well for photographs, vector images are best to ensure your sticker or label prints at the highest quality.
