Title:

An Analysis of Moiré Patterns in Halftones

Halftoning is the standard coloring method used in print. The process involves halftones, which are patterns which consist of four or less overlapping patterns of dots. However, it is possible for moiré patterns to appear in halftones, which are interference patterns which appear when two similar patterns are overlaid. It is in the best interest of printing companies to maximize the quality and consistency of the colors on their products, so it is important to minimize the presence of moiré patterns in these products. This research introduces mathematical derivations regarding where and how moiré patterns appear in halftones, as well as tools which assist in analyzing and predicting these patterns. These derivations and tools allow these moiré patterns to be more formally understood, so that they can be minimized by any party that wishes to utilize this research.
