Types of Plotter
Flatbed Plotter:
A flatbed plotter is also known as table plotter. It plots on paper that is
lying flat on a table-like surface. The flatbed plotter uses two robotic drawing
arms, each of which holds a set of pens. Most of the flatbed plotters have one
to four pens of different colors. These pens move across the paper to draw
charts or graphs on the paper. The movement of these pens is controlled by the
computer system.
Drum Plotter:
A drum plotter is also known as roller plotter. It consists of a drum or roller on which a paper is placed. Drum plotter also consists of mechanical device known as robotic drawing arm that holds a set of pens or pencils. The drum rotates back and forth to draw (or print) the graph on the paper. Drum plotter is used to produce continuous output such as to record earthquake readings.
