10、30-6:2003(E) iv ISO 2003 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each membe
11、r body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Elec
12、trotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopt
13、ed 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 bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of paten
14、t rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15930-6 was prepared by Technical Committee ISO/TC 130, Graphic technology. ISO 15930 consists of the following parts, under the general title Graphic technology Prepress digital data exchange using PDF: P
15、art 1: Complete exchange using CMYK (PDF/X-1 and PDF/X-1a); Part 3: Complete exchange 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:
16、Complete exchange of printing data suitable for colour-managed workflows using PDF 1.4 (PDF/X-3). ISO 15930-6:2003(E) ISO 2003 All rights reserved vIntroduction ISO 15930 (all parts) defines methods for the exchange of digital data within the graphic arts industry and for the exchange of files betwe
17、en graphic arts establishments. It is a multi-part document where each part is intended to respond to different workflow requirements. These workflows differ in the degree of flexibility required. However, increasing flexibility can lead to the possibility of uncertainty or error. The goal throughou
18、t the various parts of ISO 15930 has been to maintain the degree of flexibility required while minimizing the uncertainty. Many printed documents are assemblies of partial pages and/or pages created at different locations and by different organizations. The merging of these individual elements into
19、the final printing forme and the subsequent printing may take place at different locations. Some of these elements may also be routed 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 struc
20、tures are used for the creation of this type of material, but with two prevalent kinds of underlying data structures. These are vector-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
21、 and textual information. Both kinds of data structures are required along with page description information in an open electronic 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
22、data where individual objects may be in either vector or raster data structures. PDF/X-3 (Parts 3 and 6 of this International Standard) complements the other parts by defining a data format and its usage to permit the predictable dissemination of a compound entity to one or more locations, as colour
23、-managed, CMYK, gray, RGB, and/or spot colour data, in a form ready for final print reproduction, by transfer of a single file. This file contains all the content information necessary to process and render the document, as intended by the sender, coded inside a single PDF file. No other parts, neit
24、her external files nor internally embedded files, are required or permitted. 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 spe
25、cific use of the publicly available Adobe Portable Document Format. In order to achieve a level of exchange that avoids any ambiguity in interpretation of the file, a limited set of PDF objects that may be used is identified and restrictions to the use, or form of use, of those objects, and/or keys
26、within those objects are added. This version of PDF/X-3 (Part 6 of this International Standard) amplifies and refines the information provided in the earlier version of PDF (Part 3 of this International Standard), as follows. The referenced version of the Adobe Portable Document Format has been chan
27、ged from 1.3 to 1.4. The following features, introduced in PDF 1.4, have been disallowed in PDF/X-3:2003: JBIG2, Transparency, and Referenced PDF. Whereas PDF/X-3 specifies the exchange of complete material, with all elements present, there are circumstances when this is not appropriate. In certain
28、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 high- resolution contone-image files, line-art files, etc. These exchanges will generally require prior agreement between sender and receiver.
29、 The requirements for such situations are addressed in PDF/X-2 (Part 5 of this International Standard). Other exchanges may be more appropriately restricted to CMYK and spot colour data only. Such exchanges are addressed in PDF/X-1a (Parts 1 and 4 of this International Standard). ISO 15930-6:2003(E)
30、 vi ISO 2003 All rights reservedIt is anticipated that a variety of products will be developed based on PDF/X, such as readers (including viewers) and writers of PDF/X files, and products that offer combinations of these features. Different products will incorporate various capabilities to prepare,
31、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 conforming reader must be able to read and appropriately process all files conforming to a specified conformance level. Users are cautioned tha
32、t there are several different conformance levels that may be associated with PDF/X readers and writers. Two of these are generally referred to as PDF/X-3. These are defined in Parts 3 and 6 of this International Standard. It is recommended that these be referred to as PDF/X-3:2002 and PDF/X-3:2003,
33、respectively. It is important to note that the print elements of a PDF/X-1a file meet all of the requirements of a PDF/X-3 file and that a PDF/X-3 reader must also read a PDF/X-1a file. Although re-purposing of data is not a primary consideration or requirement of this part of ISO 15930, maximum fle
34、xibility will be maintained so that future requirements for re-purposing may be accommodated. An ongoing series of Application Notes 5is maintained for the guidance of developers and users of the PDF/X family of International Standards. These Application Notes, and other documents relevant to PDF/X,
