VECTOR VS RASTER

Vector graphic:

The main benefit of using a vector graphic over a raster graphic is resolution. Vector graphics are resolution independent which means no matter how large or how small you make your image, it will have “clean” edges.

Also, because the image is made up of points and edges, that data can be sent out as CNC data. This allows machines like digital plotters to understand cutting locations. 

Vector graphics are completely different to create and work with. They require an understanding of vectors and handles that control the shape of objects. Also Over lapping of shapes that are set to have transparency will mix the colors of over lapping shapes.

Raster Images:

Rasterized images are tethered directly to their resolution.  Images like photos and videos are typically rasterized. This means they are made up of pixels. Images like these are dependent on the amount of pixels per square inch (ppi) that are within the physical size of the image. Lets say you have a 5  x 10 inch image at 72 ppi that is going online. That images file size will be around 800k (other factors can influence this size). The same image file sent to a printer at 300 ppi would be around 13 times large. Vector graphics do not have this issue.

Rasterized images for on-line are in the color space of RGB (red, green, and Blue). If you need to send them to a printer they then would occupy the  CMYK (Cyan, Magenta, Yellow and Black) color space or be set to spot colors. While CMYK has a large color spectrum the RGB color space is much larger. Spot colors are even futher limited.
