Digital proofing is most successful if it starts from the final rasterised data. When both halftoning and colour properties are conserved in the proof, we call this dot for dot proofing. The match between original and proof should be obtained in three aspects: colorimetry, halftoning and print colorants. The processing includes at least resolution and colour conversion. We propose a general flow that uses an intermediate representation.An image either represents the colour accurately by giving contone values, or the halftoning by giving high resolution binary data. To reproduce both aspects well in one proof requires methods to handle both types of data together. Solutions for this are presented based on either hybrid or dual representations.
