18、nal standards bodies (ISO member 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. Internati
19、onal organizations, governmental 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 rul
20、es given in the ISO/IEC Directives, Part 3. 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
21、least 75 % of the member bodies casting a vote. ISO 15930-1 was prepared by Technical Committee ISO/TC 130, Graphic technology, with the support of ANSI Committee for Graphic Arts Technologies Standards (CGATS). ISO 15930 consists of the following parts, under the general title Graphic technology Pr

24、HS -,-,- ISO 15930-1:2001(E) Introduction ISO 15930 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 requiremen
25、ts. 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 minimising the uncertainty. Many pri
26、nted 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 form and the subsequent printing may take place at different locations. Some of these elements may also be route
27、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
28、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
29、workflow. The exchange of raster-based data using the TIFF/IT file format is defined in ISO 12639. The subject of ISO 15930 is a format for the exchange of object-based data where individual objects may be in either vector or raster data structures. Part 1 of ISO 15930 defines a data format and its
30、usage to permit the predictable dissemination of a compound entity to one or more locations as CMYK data, in a form ready for final print reproduction, by transfer of a single file. This file must contain all the content information necessary to process and render the document, as intended by the se
31、nder. This exchange requires no prior knowledge of the sending and receiving environments and is sometimes referred to as “blind“ exchange. It is platform and transport independent. These goals are accomplished by defining a specific use of the publicly available Adobe Portable Document Format as sp
32、ecified in Version 1.3 In order to achieve a level of exchange that avoids any ambiguity in interpretation of the file, it identifies a limited set of PDF objects which may be used and adds restrictions to the use, or form of use, of those objects, and/or keys within those objects. It includes two c
33、ompliance levels, PDF/X-1 and PDF/X-1a, that differ only in their allowed use of OPI references, and encryption which are allowed in PDF/X-1 but not in PDF/X-1a. Whereas PDF/X-1 and PDF/X-1a specify the exchange of complete material, primarily as CMYK data, with all elements present, there are occas
34、ions where this is not appropriate. In certain workflows some or all of the referenced elements may be more logically present at the receiving site, or may be exchanged at a different time. These include fonts, high resolution contone image files, or line art files. These exchanges will generally re
35、quire prior agreement between sender and receiver. Further, evolving colour management capabilities may allow elements to be exchanged more expeditiously in colour spaces other than CMYK. The requirements for such situations are addressed in later parts of ISO 15930. Although re-purposing of data is
36、 not a primary consideration or requirement of this part of ISO 15930, maximum flexibility will be maintained so that future requirements for re-purposing may be accommodated. It is anticipated that a variety of products will be developed around PDF/X-1, such as readers (including viewers) and write
37、rs of PDF/X files, and products that offer combinations of these features. Different products will incorporate various capabilities to prepare, interpret and process conforming files based on the application needs as perceived by the suppliers of the products. However, it is important to note that a
38、 conforming reader must be able to read and appropriately process all files conforming to a specified conformance level.

40、ite data Part 1: Complete exchange (PDF/X-1). ANSI CGATS.12/1 is based on Portable Document Format Reference Manual Version 1.2 as extended by Adobe Technical Note #5188. This part of ISO 15930 is based on the Adobe Portable Document Format Version 1.3. Users are cautioned that there are currently t
41、hree different conformance levels that may be associated with PDF/X readers and writers. Two of these are generally referred to as PDF/X-1 and are those compatible with ANSI CGATS.12/1-1999 and the PDF/X-1 compatibility level of this part of ISO 15930. It is recommended that these be referred to as
42、PDF/X-1:1999 and PDF/X- 1:2001 respectively. Further this part of ISO 15930 makes provision for a 2nd conformance level which does not allow OPI references or encryption. This should be referred to as PDF/X-1a:2001. While a PDF/X-1:2001 reader should accept and properly read files conforming to both
43、 PDF/X-1:2001 and PDF/X-1a:2001 conformance levels, readers meeting the other two conformance levels should not be expected to properly read files outside of their own conformance level. An ongoing series of Application Notes 1 is maintained for the guidance of developers and users of the ISO PDF/X
44、family of International Standards. They are available from NPES The Association for Suppliers of Printing, Publishing and Converting Technologies in the standards section at http:/www.npes.org/standards/workroom.html. Attention is drawn to the fact that it is claimed that compliance with this part o
45、f ISO 15930 may involve the use of a patent concerning data encryption (clause 6.17). ISO takes no position concerning the evidence, validity and scope of this patent right. The holder of this patent right has assured ISO that they are willing to negotiate licenses under reasonable and non-discrimin
46、atory terms and conditions with applicants throughout the world. Information may be obtained from: RSA Data Security, Inc., 100 Marine Parkway, Redwood City, CA 94065-1031, USA. Attention is also drawn to the possibility that some of the elements of this part of ISO 15930 may be the subject of paten
47、t rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights.
