ABSTRACT:
A technique for screening an image for half-tone reproduction by image reproduction apparatus including a marking device which is operative to mark a medium along a multiplicity of parallel marking lines including the steps of providing a digital representation of density values of an original image, storing dot shape information representative of a screen function in a line-by-line, input density-by-input density arrangement and extracting the dot shape information from storage for the density values in the form of information that designates on and off points for each marking line. Apparatus for carrying out the technique is also disclosed.
