ABSTRACT:
A technique for generating a screened reproduction of an image comprising the steps of providing a representation of an original having input density values representing the grey levels of various locations of the original for a given color separation, defining a desired screen dot arrangement for the image, and writing screen dots in a line by line fashion, wherein each screen dot is made up of a plurality of segments whose length and location determines the dot configuration and whose length and location is determined by a digital operation including interpolation employing screen threshold values at at least two spaced locations and by employing the input density information relating to the original.
