What is the difference between Bitmap and EPS files?
These two file names represent the difference between what is called “raster” (Bitmap, TIF, JPG, etc.) and “vector” (EPS, WMF) images. A raster image saves information about every dot (pixel) that makes up an image. These files tend to be larger in size because more information is being saved about the image. Raster images sometimes require printing in a process format and may not have as smooth of edges on solid color (spot) printing. A vector image makes up a picture by storing to points and the angle of the curve between the two points. A vector logo will typically have many points and curves, but far less information is necessary to be stored, therefore resulting in a smaller file size. Vector images are the preferred option for spot color printing and produce sharp, crisp edges in the print process.
