The Illusion of Halftone Dots

Continuous Tone vs Halftone Dots: The Grand Illusion

Nature provides a spectrum of light that is far greater than our eyes can see. Our eyes can recognize over 17 million colors, which gives us a pretty smooth interpretation of what light and colors that actually exist. However, the image reproducton process is not so articulate. The printing process actually depends on optical illustion to simulate what our eyes can see. On the computer monitor, pixels smaller than the eye can perceive from a distance, deliver a quite believable picture. But  the printig process depends on tiny symmetrical dots to carry the illusion. How we shape the relative sizes of these dots is critical to pulling off this grand illusion. It's not magic, but it's close.
