13、er bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, government
14、al and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Direct
15、ives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodie
16、s casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15930-4 was prepared by Technical Committee ISO/TC 130, Graphic technology, wit
17、h the support of ANSI Committee for Graphic Arts Technologies Standards (CGATS). ISO 15930 consists of the following parts under the general title Graphic technology Prepress digital data exchange using PDF: Part 1: Complete exchange using CMYK data (PDF/X-1 and PDF/X-1a); Part 3: Complete exchange
18、suitable for colour-managed workflows (PDF/X-3); Part 4: Complete exchange of CMYK and spot colour printing data using PDF 1.4 (PDF/X-1a); Part 5: Partial exchange of printing data using PDF 1.4 (PDF/X-2); Part 6: Complete exchange of printing data suitable for colour-managed workflows using PDF 1.4

20、ghts reserved v Introduction ISO 15930 (all parts) defines methods for the exchange of digital data within the graphic arts industry and for the exchange of files between graphic arts establishments. It is a multi-part document where each part is intended to respond to different workflow requirement
21、s. These workflows differ in the degree of flexibility required. However, increasing flexibility can lead to the possibility of uncertainty or error. The goal throughout the various parts of ISO 15930 has been to maintain the degree of flexibility required while minimizing the uncertainty. Many prin
22、ted documents are assemblies of partial pages and/or pages created at different locations and by different organizations. The merging of these individual elements into the final printing forme and the subsequent printing may take place at different locations. Some of these elements may also be route
23、d to multiple sites for incorporation into other documents. Each of these elements is referred to in ISO 15930 as a compound entity. A variety of data formats and structures are used for the creation of this type of material, but with two prevalent kinds of underlying data structures. These are vect
24、or-based data for the encoding of line art and textual information and raster-based data for the encoding of image information, including previously rasterized line art and textual information. Both kinds of data structures are required along with page description information in an open electronic w
