Media Manager Profiling Guide Version 7 : Halftone Screen
This page last changed on Aug 22, 2008 by johannaf.
A type of AM Screening halftone structure produces a pattern of halftone dots with a fixed frequency, where the size of the dot varies with gray level. This method allows the uses to create custom patterns defining frequency, angles and dot shape. An image in which continuous tones are simulated by regular spacing ("as if printing through screen") of small dots. The finer the dot grid, the greater detail can be represented in the reproduction, but smaller dot sizes can also result in fewer effective continuous-tone levels in the reproduction. A process for creating images. Halftone screening can be done at different angles and the line density varies over a wide range (50-500 lines per inch). Printing a black & white photograph on a press or printer requires the creation of a single halftone. Four color process printing requires a separate halftone for each of the process colors.
