Types of Modulation Halftone Images in Printings

Reproduction of the original complex includes raster halftone process. Feature playback halftone originals are the need to divide the tones to individual line items whose size is outside the definition of an eye. This is because during printing, any print form to print must contain only printable and. There are integral and synthesizing techniques for creating these elements. In integral methods bitmap item (printed) occurs when plays at all of its form. lement is created from a bitmap form small particles, when synthesizing method. This method has recently found considerable proportions (in conjunction with the active development of computer technology). Many literary sources inherent allegation of the existence of only two basic kinds of modulation, when a halftone images playing. Some printing magazines when considering playing tonal images are sent only to amplitudemodulated and frequencymodulated screen and xploring line amplitude and frequency modulation. In interpreting these modulations is an analogy with radiotehnikoj, explaining the transfer necessary signal a highfrequency analog signal harmonic. However, the human eye perceives an optical output for continuous wedge as analogue signal that the size of the bitmap elements in many cases is beyond the resolution of the eye.
