Introduction to Plotter:

A plotter is a type of printer that prints vector graphics. A plotter is a special printer that creates high-quality drawings and graphics. Unlike regular printers, which spray ink, plotters use pens or other tools to draw precise lines and shapes. They are commonly used in fields like engineering, architecture, and graphic design. It may also use vector graphics files or commands to draw continuous point-to-point lines.

The first plotter was created by Remington-Rand in 1953. It was used in combination with the UNIVAC computer to make technical drawings.

Types of Plotters:


1. Drum Plotter : A drum plotter is a type of plotter that uses a cylindrical drum to hold the paper or material being printed on. The pen or cutting tool moves across the surface of the drum while the paper is fed through, allowing for large-scale prints.
  • Key Features : 
    • Large Format: Drum plotters can handle larger media sizes, making them suitable for architectural plans, engineering drawings, and posters.
    • Continuous Feed: As the drum rotates, it allows for continuous feeding of the material, which is useful for long prints. 
    • High Precision: They can produce very detailed lines and graphics, making them ideal for technical applications.
  • Advantages:
    • Wide Range of Materials: Can work with various media types, including paper, film, and vinyl.
    • Efficient for Large Prints: Perfect for producing large technical drawings without the need for multiple sheets.
  • Disadvantages:
    • Cost and Size: Generally more expensive and larger than other types of plotters. 
    • Complex Operation: May require specific skills to operate effectively.
  • Example: An example of a drum plotter might be in a design firm creating a large architectural plan that needs to show every detail clearly and accurately.
key notes:
  • Cylindrical Drum: The round component that holds and moves the paper.
  • Continuous Feed: The method of feeding the material through the plotter without stopping.
  • Drum plotters are valuable for producing high-quality, large-format prints, particularly in technical fields.

2. Flatbed Plotter:

A flatbed plotter is a type of plotter that uses a flat surface to hold the paper or material being printed. Unlike drum plotters, which use a cylindrical drum, flatbed plotters keep the material stationary while a movable pen or cutting tool moves over it.

  • Key Features:
    • Flat Surface: The material is placed on a flat bed, which allows for easy loading and unloading.
    • Precision: Flatbed plotters can produce highly detailed and accurate prints, making them ideal for technical drawings and designs.
    • Versatility: They can handle various materials, including thick media like cardboard, plastic, and vinyl.

Advantages:
  • High Accuracy: Excellent for producing intricate designs and precise graphics.
  • Wide Material Range: Can work with various media types and thicknesses.
  • Ease of Use: Loading and unloading materials is straightforward, as you don’t need to roll anything.
Disadvantages:
  • Size: Flatbed plotters can be bulky and require more space.
  • Cost: Generally more expensive than basic printers or some other plotter types.
  • Speed: May be slower compared to other plotters for large jobs.
  • Example
  • An example of a flatbed plotter could be used in a sign-making shop to create detailed graphics on rigid materials, like creating a custom sign from a sheet of acrylic.

Key notes:
  • Flat Surface: The level area where the material is placed for printing.
  • Precision: The quality of being exact and accurate in the drawings.
  • Flatbed plotters are valuable in industries that require detailed prints on various materials, balancing accuracy with versatility.
