This part of ISO 12647 specifies a number of process parameters and their values to be applied to four-colour publication gravure printing. The parameters and values are chosen in view of the complete process covering the process stages “colour separation”, “making of the printing forme”, “proof production”, and “production printing”.This part of ISO 12647 is applicable,— directly, to publication gravure printing, including magazines, catalogues, and commercial materials,— directly, to half-tone and continuous tone proofing processes that predict the colourimetric results of gravure printing, and— by analogy, to process-colour gravure package printing.It is not directly applicable to the specifics of the transformations necessary to relate digital input data to the data used to create the cylinder engraving data and/or the proofing process.
