In printing, the Moiré effect is an undesirable pattern of interference that can occur when printing overlapping lines or dots. This interference pattern is caused by the interaction of the screen pattern with the printed image. The Moiré effect can be minimized by using a screen with a lower frequency, or by breaking up the screen pattern with a “stochastic” screen.

The Moiré effect can also occur when scanning a halftone image with a digital scanner. This is because the scanner’s pixel grid does not line up perfectly with the screen’s pixel grid. The Moiré effect can be minimized by using a high-resolution scanner, or by using software to “de-screen” the image.

In printing, a moiré is an undesirable interference pattern that can result from the superposition of two grids. It is often caused by the misalignment of the screen or film used to make the print, or by the misalignment of the paper during printing.

Moiré can also occur when scanning a halftone image with a scanning device that uses a raster that is not aligned with the halftone screen. This misalignment will cause a moiré pattern in the resulting image.

Moiré can be reduced or eliminated by using a higher screen ruling, by using a screen that is rotated slightly with respect to the film or paper, or by using a scanning device that uses a raster that is aligned with the halftone screen.

Moire is an important printing technique that allows for the creation of high-quality prints with a wide range of colors. This printing method is often used for photographs and other artwork that require a high level of detail and color accuracy. Moire prints are also more resistant to fading and other forms of damage than traditional prints, making them a good choice for archival purposes.

CJ grew up admiring books. His family owned a small bookstore throughout his early childhood, and he would spend weekends flipping through book after book, always sure to read the ones that looked the most interesting. Not much has changed since then, except now some of those interesting books he picks off the shelf were designed by his company!
