30、important professional printing processes of the graphic arts industry. The initial concept was that the groundwork for the series was laid down in ISO 12647-1. This part of ISO 12647 differs from that concept because flexographic printing has changed significantly since ISO 12647 was initially conc

31、eived.This edition of this part of ISO 12647 differs from the earlier edition by not defining specific printing condition aims but instead requires that a specific reference printing condition (characterization data set) be specified. Flexographic printing differs from other printing procedures by u

32、sing a variety of printing machine architectures, ink sequence, ink types, anilox rollers, substrate types, etc. Each of these involve different printing condition and process control aims. This part of ISO 12647 requires that the colour of the printed product match a characterization data set or a

33、printing condition agreed upon by the provider and the receiver and specifies minimum requirements and tolerances to be communicated and produced.The purpose of a proof is to simulate the visual characteristics of the finished printed product as closely as possible, which often becomes a contractual

34、 agreement between provider and receiver. In order to visually simulate a particular printed product, off-press proofing processes might require values for various process control aims (e.g. solid tone colouration, tone value increase) which are different from those of the printing process they are

35、meant to simulate. This is caused by differences in phenomena such as gloss, light scatter (within the print substrate or the colourant), ink trap or overprint efficiency, metamerism and transparency. Such differences are likely for those off-press proofing processes in which the print substrate, th

36、e colourants and the technology for applying them are significantly different from flexographic printing. In such cases the user or the supplier needs to ensure that appropriate corrections are specified.Although this market uses colour proofing on electronic displays, and it was the intent of the a

37、uthors to reference the requirements for such proofing techniques, ISO/TC 130 has not yet defined a standard in this area that can be referenced. It is hoped that such work will progress and be available in the near future.In addition, work has started on ISO 17972, Graphic technology Colour data ex

38、change format. ISO 17972-4 will include exchange specifications for spot colour characterization data to facilitate the communication of spot colour data.
