When I first started out in graphic design, it was just as graphic design was changing from the manual, paste-up / stripped-in, hand-drawn style of design into more of the computer-based graphics style that we now have. It was an interesting time and HUGE learning curves for everyone. 16 or 17 years later and there are still HUGE learning curves… there is just so much to know!
One of the first things that I learned in college was the difference between a VECTOR-based graphic and a RASTER-based graphic. It’s an important question actually… and anyone who owns a digital copy of their logo really should know the answer. It can potentially save you a lot of headaches, as well as time and money…
Depending on what you want to do with your logo, there are different formats that your logo can exist in. For example, if you want to put your logo up on your website, it requires a much different format, colour profile and resolution than the logo you send to Snappy’s Sign Makers Emporium for the vinyl lettering for your windows. A logo that is going to be made REALLY BIG must created differently than a logo that is going to be printed really small.
Let’s start with what a RASTER graphic is.
Everyone who has visited a website or taken a digital photo knows what a raster graphic is… even if you don’t know it. A raster image is created using pixels (ie. small squares) in a finite number of pixels per inch. The more pixels per inch (PPI) – or if you are old school like me… dots per inch (DPI) – the better the resolution. So, the more dots or pixels you have in that inch of space = more information = a crisper and clearer image. Conversely, fewer pixels means that there is less information and therefore the image is less clear and it appears fuzzy and grainy looking. (see below)

Raster images can have a wide range of resolutions depending on what the intent of the image is… for example a graphic that you want to put up on a website typically has a resolution of 72 dpi or 96 dpi, this keeps the size of the file small and makes the website faster to load up and view. Images that you are wanting to print out at a Walmart insta-print machine, these typically work out to around 240 dpi – 300 dpi. Other types of high-resolution printing require images that are 300 dpi or more.
In short, a raster graphic is flattened artwork composed of pixels that are not easily changeable, it handles continuous colours beautifully, but the bigger you make it, the less good it looks. Upon scaling up, the edges become jagged-looking and bit-mapped, and in photographs, there is a tendency towards colour halos forming between areas of contrast or opposing colours. Just remember…. all photographs are raster images, all web graphics are raster images.
These file formats are always raster images: JPG, TIF, GIF, PSD, BMP.
Okay… I get it, so then, what is a VECTOR graphic?
A vector based graphic is usually a drawing, illustration or logo that has been created in a drawing program such as Adobe Illustrator or CorelDraw. It has been built using paths (editable lines, points and shapes). These path edges stay smooth, even if it is scaled up by 1,000,000 times, simply because these paths are not made up of a finite number of pixels or dots (ie. like a raster) but are comprised of starting and ending and middle points, and lots of mathematical equations to adjust the curves and lines in between. Typefaces are all created using vector principles (this is why you can have them in so many sizes).

Vector images basically have 1 resolution. The highest. It is the best quality for output you can get and it is the most versatile format, it’s easy to edit and, depending on your specific needs, easy to work with. You can change a vector graphic into a raster graphic just by saving it out that way. However, you cannot change a raster into a vector just by saving it as an EPS file. You cannot make a photograph into a vector. You cannot make a vector by placing your raster image in Illustrator and then saving it. You can ONLY make a vector by creating/drawing it that way.
In short, a vector graphic is the best quality image you can have. It is fully editable, versatile, and infinitely scalable…the edges stay smooth and clean regardless of how much you blow it up. Logos are usually originally created as a vector graphic, as are a lot of technical drawings and illustrations.
These file formats are always vector graphics: AI, CDR, DRW, SVG.
These file formats are often vector graphics (but not always): EPS, PDF
(raster images can be saved this way too, but that doesn’t make them a vector).
We want you to look good…
Here at Sharper, we get many logos from our customers every day, in many different formats. Because we are printing on a wide range of products – like moving postcards, design-your-own tote bags, pet food lids, personalized magnets, or dental stationery – it is important that we have access the best quality logo available so that your products look GREAT, and also so that your advertising image is as professional as you are. For that reason, we prefer to not use web graphics… there is just not enough information to print cleanly on an orthodontic recall card let alone enlarging it for a 9×13 tote bag (it just looks bad). Additionally, some products have special printing needs, where a vector based graphic is required for proper output. Take a look at our logo specifications for more details.
Sometimes however, life happens and the vector version of the logo is just… gone. You know…the designer moved away, the computer melted down, someone was a bit aggressive with the file clean-up…. When this happens, just let us know. We also offer a fabulous logo redraw service.
