Why is an EPS file the best format for supplying logos?
What we are after is a vector image format. Vectors are mathematical ‘plots’ and are therefore fully scalable since there are no pixels in the image. Enlarging pixels just gives bigger pixels – which results in jagged and fuzzy images. This is the problem with trying to enlarge web graphics – they are already very low in quality and are in pixels (raster images). Any image is either a raster or a vector and it’s the vectors that work better for logos and the like. EPS (Encapsulated PostScript) files that are created in programs like Adobe® Illustrator and Corel Draw are vector images. EPSs are cross-platform and recognised by all major publishing and illustration packages. An EPS can also be used by other industries (such as signwriting) who work with different computer systems and software. When is an EPS not a useful EPS? Taking a raster image and putting it into these programs gives a file that can be saved in an EPS format but it is not a vector image. It’s still a raster image and
