Halftone Image Description

A halftone is an image that is made up of a series of dots rather than a continuous tone.

These dots can be different sizes, different colors, and sometimes even different shapes.

Larger dots are used to represent darker, denser areas of the image, while smaller dots are used for lighter areas.

Since a halftone image is made up of discrete dots, it requires significantly less ink to print than a continuous tone image. When printed with black ink, a grayscale image converts to a pattern of black dots that simulates the continuous tones of the original image. 

When printing a grayscale image with black ink you essentially are printing a B&W photograph because the halftone is simply black dots of ink. This includes:

  • Photographs, black and white or color
  • Pencil drawings with shading
  • Grey (shaded) bar and boxes
  • Grey lines and text
  • Grey drawings
  • Grey boxes with white text or with black text
  • Graphs and charts with multiple shading

NOTE: Color text and images may become black when scanned.
