 Moiré Patterns [encyclopedia]
One of the more common occurrences of moiré patterns is found in computer monitors and television sets where we see an ordered wavy pattern is superimposed over the screen in a series of ripples.
Moiré patterns also are a common problem in scanned images due to interference between the printed dot pattern and the reflection of the image.

 The Theory of the Moire Phenomenon by I. Amidror
This book is intended for students, scientists, engineers and any readers who wish to widen their knowledge of the moiré effect; on the other hand it also offers a beautiful demonstration of the Fourier theory and its relationship with other fields of mathematics and science.
In later chapters the theory is extended to the even more interesting cases of polychromatic moirés and moirés between non-periodic layers.

 The Q Mystery
The new pattern you see is called a Moiré pattern, formed when two patterns partly overlap.
If the pattern on the screen is even slightly uneven, the Moire pattern will be very uneven.
Because of this, Moiré patterns can be used to check that objects are flat, or evenly curved.

Failure to do this results in a moiré pattern not present on the original image.
(2) Because of the additional process colors, moiré would be more prevalent if conventional halftone screening (instead of stochastic screening) is used in the separations.
In order for this process to work satisfactorily, all the images must be in register, and the various colored marks must be properly aligned between colors.

 Seybold Report on Publishing Systems Vol 20, Num 03
That is, the moir‚ pattern is broken up by fuzzing it with visual ``noise.'' This works, but it can result in some loss of quality unless the parameters are chosen carefully.
For color printing, we need a group of four combinations that don't show too much moir‚ when they are overprinted, which means the angles should be nearly 30ø apart.
To generate an acceptable irrational screen, we must somehow deal with the error between the dot position that the screen calls for and the dot position that is possible.

Such patterns are good at avoiding moiré effects (artifacts) that originate from the interference with repetitive CFA patterns.
In pseudo-random patterns the number of neighbors in a specific color is variable, and therefore a spatial chrominance pattern will appear: something highly undesirable.
In most cases a 3-color red-green-blue (RGB) pattern is used, although others exist too: 3-color complementary YeMaCy, or mixed primary/complementary colors, and 4-color systems where the fourth color is white or a color with shifted spectral sensitivity.

You may, however, be surprised to learn that the moiré pattern on paper differs from the moiré pattern on screen.

 Descreen methods for Moiré patterns
You can see similar moiré patterns if you lay two pieces of wire window screening on each other, rotate one at an angle from the other, and look through the two of them at a light.
Traditional procedures to eliminate moiré patterns without the Descreen filter often include scanning at 2X or more the desired resolution, apply a blur or despeckle filter, resample to half size to get the desired final size, then use a sharpening filter.
Scanning at high resolution with the Descreen filter and then resampling smaller is effective to remove moiré, but it will definitely consume vast amounts of memory, and so may not even be possible on many computers.
