Raster images excel at displaying subtle color tones. This is why it is one of the best suited formats for detailed images. Today, most pictures taken with digital cameras are Raster images. Raster file formats come in TIFF, JPEG, GIF or BMP, depending on the sort of data compression process used. On the other hand, Vector images are mathematically inclined as they use a mixture of lines and curves to form their images. Basically, it uses mathematical expressions to describe an image. Some file formats of Vector images include PDF and SVG. They aren’t quite as popular as Raster formats, however some printers will ask for this type of file.
So when you’re considering what format to go with, note that Raster provides very high resolution compared to vector formats. However, the final product printed isn’t dependent on just how high the resolution of your Raster format is, but also on the internal specifications of the machine used in printing. Vector formats have the superior edge in terms of flexibility and they are very easy to use. Also, because they aren’t heavily dependent on resolution, Vector graphics don’t suffer from image degradation like Raster images.
