Continuous tone means that the print is produced by a smooth flow of colours between the separate printed “pixels”. Continuous tone photographic images on silver halide contain an infinite range of colours within a very large gamut, and no dot structure. They are produced via a wet chemical process that uses the reaction of light on substances in the photo-sensitive paper to achieve incredibly smooth images. This result in a more realistic print, compared to Inkjet (dots) print or press prints (raster).
