What does "vector" mean?
Vector artwork is a term for die-cut printing.
When it comes to artwork there are two different styles: Vector and Raster. Raster files are great for digital printing but can't be cut to shape. Whereas vector artwork can be digitally printed and cut to shape. Vector programs likes Illustrator, InDesign or CorelDraw utilize a more mathematical programming format that creates traceable lines, shapes, attributes and components. Raster images are a series of dots that can't be defined for cutting.
Typical vector artwork file extensions consist of .AI, .EPS, .PDF, .CDR or .INDD. Vector files are usually high-resolution and can be scaled up and down in size without compromising print quality, unlike raster files, that can become blurry, choppy or pixelated when enlarged. In almost every instance for digital printing, if you have a vector file, it is best to supply your sign company with that file over any other files as it will yield a very good print.
The reason vector files are able to be cut-to-shape (die-cut, computer cut, laser cut, contour cut) is because the program itself can create outlines that a computer can read. These cut lines guide a laser or blade around text, images and objects so that the artwork, when weeded, will stand alone without a background creating a custom cut which is very popular for vinyl lettering, vehicle graphics, window graphics and wall graphics.
The picture to the left shows an example of vector artwork that has been cut out to shape and applied to an SUV window. If the artwork wasn't vector then the whole piece would have to be printed with a black background to try and match the window tint which would definitely not look as good as have no background. The digitally printed "Fire House" logo is combined with cut vinyl lettering for a completely custom and unique look.
