• RASTER: A grid of pixels, color or grayscale, that makes up an image. Scaling can result in pixelization.

• VECTOR: Computer graphics images that are defined by 2D points. X and Y coordinates are used to calculate the path. Can be scaled without loss of resolution.

• EPS: (Encapsulated PostScript) A non-proprietary graphics file format that includes vector data and a low-resolution raster preview. The standard file format for exporting PostScript files.

• Spot Color: any color generated by an ink, pure or mixed, that is printed using a single run.

• PostScript: An embedded language for printers created by Adobe. It was created for plotting vector drawings and for printers to print digital text (instead of using plates like in a typewriter). PostScript 3 has 4096 shades of gray and allows Spot Colors to be included in a file with other types of color spaces (CYMK/RGB).
