Abstract:
1. A method for obtaining a preferred color conversion implementation for rendering of an image containing halftoned data, comprising: providing a plurality of pixel-value to color rendering value mappings, each pixel-value to color rendering value mapping corresponding to a distinct color conversion implementation for converting a pixel-value of the image to a pixel-value in a colorspace used for rendering the image, each color conversion implementation corresponding to a distinct halftone type; processing, using a processor, the image and generating therefrom a plurality of tags denoting the frequencies of halftoned data of the image containing halftoned data; identifying different classes of halftones from the tags to obtain a plurality of halftone classifications; selecting one of the halftone classifications; selecting one of the plurality of pixel-value to color rendering value mappings, based upon the selected halftone classification, to obtain the preferred color conversion implementation for rendering the image containing halftoned data; and rendering, using a printer, the image containing halftoned data using the selected pixel-value to color rendering value mapping.
