In the printing industry, it is also a synonym for "ripping", and can apply to images as well as vector files. For example, if you have a contone image, whether RGB or CMYK, that data is going to be converted to a set of line screens, often expressed as 1-bit TIFFs, and then burned directly to plates. This process is also sometimes called rasterization, because not just the vectors/fonts, but also the bitmap images are getting converted to a line-screen equivalent.
