    14、deration of national 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 com

    15、mittee. International 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 accord

    16、ance 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 adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard require

    17、s 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 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12639 was prepared by Technical

    18、Committee ISO/TC 130, Graphic technology. This second edition cancels and replaces the first edition (ISO 12639:1998), which has been technically revised to add new capabilities, as well as a new constrained conformity level call Profile 2 (P2) to supplement the previously defined Profile 1 (P1), wh

    19、ich is unchanged. New capabilities include the following: expanded LW palette to support up to 65 535 colours; support for up to 32 separations; new file format “SD” for copydot data with CCITT G4 compression; new compression schemes: Flate and JPEG; “FP” file format is now defined as normative. ISO

    20、 12639:2004(E) vi ISO 2004 All rights reservedIntroduction The goal of ISO/TC 130 in developing the initial version of ISO 12639 was to enable the interchange of various types of rasterized colour and monochrome image data among electronic digital systems used in prepress image processing, graphic a

    21、rts design and related document creation and production operations. It was, and is, intended for use as a media-independent means for such interchange, and therefore is applicable to facilitate interchange through a variety of mechanisms such as, but not limited to, network, magnetic and optical med

    22、ia. Both ISO 12639:1998 and this second edition are based on the Adobe TIFF, Version 6.0 file format, and both extend and restrict the technical features of that format. This second edition of ISO 12639, though based on ISO 12639:1998, specifies new capabilities, as well as a new constrained conform

    23、ity level called Profile 2 (P2) to supplement the previously defined Profile 1 (P1), which is unchanged. The key added capabilities include a normative final page (FP) format; a new SD file format with optional G4 compression for copydot data; definitive ways to use RGB and CIELAB colour spaces in C

    24、T, as well as 16-bit-per-channel data in CT; JPEG compression in CT and MP; Flate compression in all formats except LW, HC and BL; spot colours (colours other than cyan, magenta, yellow and black) in LW, CT, HC, MP, BP, BL, and SD; and support for up to 65 535 colours in LW colour palettes. The new

    25、P2 compliance level incorporates all features of P1 and defines a constrained compliance level for these new capabilities. All of the features of ISO 12639:1998, including the constrained level of conformity called Profile 1 (P1), have been retained. It should be noted that the P1 formats for CT (Co

    26、lour Picture), MP (Monochrome Picture), and BP (Binary Picture) files are compatible with the popular TIFF 6.0 files for CMYK (Separated) Images, Monochrome Images and Bilevel Images respectively. The P1 formats for HC (High-Resolution Continuous- Tone), LW (Line-Art) and BL (Binary Line-Art), thoug

    27、h not compatible with TIFF 6.0, are designed to be easier to implement within desktop systems by limiting the range of options and selections. The Profile 1 and 2 formats allow for a broader usage of this International Standard by allowing conformance to simplified, restricted subsets of functionali

    28、ty supported by many popular application software systems used in the prepress, graphic arts document processing and computer graphics and imaging industries. A P2-compliant reader will also read all P1-compliant files. As a historical note, ISO 12639:1998 was based on the American National Standard

    29、 ANSI IT8.8, Graphic technology Prepress digital data exchange Tag image file format for image technology (TIFF/IT). INTERNATIONAL STANDARD ISO 12639:2004(E) ISO 2004 All rights reserved 1Graphic technology Prepress digital data exchange Tag image file format for image technology (TIFF/IT) 1 Scope T

    30、his International Standard specifies a media-independent means for prepress electronic data exchange using a tag image file format. This International Standard defines image file formats for encoding colour continuous-tone picture images, colour line-art images, high-resolution continuous-tone image

    31、s, monochrome continuous-tone picture images, binary picture images, binary line-art images, screened data, and images of composite final pages. 2 Compliance levels and identification 2.1 General This International Standard has three levels of conformance: TIFF/IT (also referred to as full TIFF/IT),

    32、 TIFF/IT-P1 and TIFF/IT-P2. All conformance levels are intended to support a media-independent means for the exchange of various images used in the prepress, printing, graphic arts, and information processing fields. TIFF/IT-P1 conformance provides a minimized set of options to permit simpler implem

    33、entation and compatibility, where possible (for CT, BP, and MP files), with commonly available TIFF 6.0 readers and writers. TIFF/IT-P1 is intended for use where the full set of TIFF/IT options is not required. TIFF/IT-P2 is also a subset of the TIFF/IT specification. TIFF/IT-P2 incorporates all of

    34、the options defined for TIFF/IT-P1 and, in addition, provides support for spot colours, a larger LW colour palette, the SD file format for screened data, and additional compression methods. Only those TIFF/IT fields defined in this International Standard are required to be written, recognized and in

    35、terpreted by conforming implementations. TIFF fields that are unclassified or not referred to in this International Standard are not required to be supported for an implementation to conform to this International Standard. If an unsupported field is read, processing of that field is at the discretio

    36、n of the reader. The reader shall follow the strategy described in TIFF and attempt to process the file while ignoring unsupported fields (see Annex A). This International Standard specifies the requirements for conforming TIFF/IT, TIFF/IT-P1 and/or TIFF/IT-P2 files for specific image data types. Fi

    37、les for each specific image data type that conform to the requirements of this International Standard shall be considered conforming TIFF/IT, TIFF/IT-P1 and/or TIFF/IT-P2 files for the specific image data type. Readers that accept and process these files shall be considered conforming TIFF/IT, TIFF/

    38、IT-P1 or TIFF/IT-P2 readers for the specific image data types. Writers that generate and output these files shall be considered conforming TIFF/IT, TIFF/IT-P1 or TIFF/IT-P2 writers for the specific image data types. Where requirements of this International Standard and TIFF 6.0 are in conflict, this

    39、 International Standard shall take precedence. 2.2 Image file type identification TIFF/IT provides the ability to represent the data structure of a wide range of printing and graphic arts images. The identification of the individual image file types is as follows (see Annex B): TIFF/IT-CT colour con

    40、tinuous-tone picture image data; TIFF/IT-LW colour line-art image data; ISO 12639:2004(E) 2 ISO 2004 All rights reserved TIFF/IT-HC high-resolution continuous-tone image data; TIFF/IT-MP monochrome continuous-tone picture image data; TIFF/IT-BP binary picture image data; TIFF/IT-BL binary line-art i

    41、mage data; TIFF/IT-SD screened data image data; TIFF/IT-FP final page data. 2.3 TIFF/IT conformance For conformance to this International Standard, all image file types do not have to be implemented. Each image file type described in Clause 7 may be individually implemented. Files, readers or writer

    42、s may be identified as conforming for either all image file types or specifically identified image file types. Conformance with TIFF/IT requires implementation of the requirements for all image file types as described in Clause 7. Conformance with a specific image file type or types requires identif

    43、ication of the specific image file type using the identification defined in 2.2 (e.g. TIFF/IT-CT). 2.4 TIFF/IT-P1 conformance TIFF/IT-P1 conformance provides the ability to represent the data structure of various images in as simple and straightforward a way as possible in order to support image-fil

    44、e exchange with prepress, printing, graphic arts, and information processing systems and applications. TIFF/IT-P1 is a subset of TIFF/IT. Conformance with TIFF/IT-P1 requires implementation of the requirements for all image file types as described in Clause 7. Conformance with a specific image file

    45、type or types requires identification of the specific image file type using the identification defined in 2.2 with the designation “/P1” appended (e.g. TIFF/IT-CT/P1). 2.5 TIFF/IT-P2 conformance TIFF/IT-P2 conformance provides the ability to represent the data structure of various images in as simpl

    46、e and straightforward a way as possible in order to support image file exchange with prepress, printing, graphic arts, and information processing systems and applications. TIFF/IT-P2 is a subset of TIFF/IT and forms an intermediate conformance level between TIFF/IT and TIFF/IT-P1. Conformance with T

    47、IFF/IT-P2 requires implementation of the requirements for all image file types as described in Clause 7. Conformance with a specific image-file type or types requires identification of the specific image file type using the identification defined in 2.2 with the designation “/P2” appended (e.g. TIFF

    48、/IT-CT/P2). 2.6 Conformance identification Conformance with the provisions of this International Standard shall be identified individually for files, readers, and writers. The accepted terminology shall be the image-file type followed by the designation “file”, “reader” or “writer” (e.g. TIFF/IT wri

    49、ter, TIFF/IT-CT/P1 reader, TIFF/IT-LW file). 3 Normative references The following referenced documents are indispensable for the application of this document.
