Introduction

The technical contents of this standard for communication between electronic or digital switching system for various types of color or monochrome raster image data file, which these files can be used in the prepress image processing, print design and related document creation and generation operations. The purpose of the standard is to provide a and media-independent exchange tools between the various media for data exchange, such as network, magnetic media and optical media.

Defined in this standard image file format for color continuous-tone images, line images color, high-resolution continuous tone images, even monochrome Continuous tone image, binary image and the binary image lines, plus network data and the composite final page image. The standard has three levels of specification.

TIFF/IT, TIFF/IT-P1 and TIFF/IT-P2.

TIFF/IT, also known as full TIFF/IT. TIFF/IT-P1 specification is a subset of TIFF/IT, providing a minimum of optional Range, allows only relatively simple operation, and read and write procedures and common TIFF6.0 compatible (for color continuous tone images, binary image and in terms of monochrome image files). For continuous-tone color images, monochrome image and binary image file format P1 respectively CMYK (points Color) compatible with the image, monochrome image and binary image TIFF6.0 file. For high resolution continuous tone images, line images and binary line Article image P1 file format, although not compatible with TIFF6.0, but by limiting the range of options, the implementation of the desktop system easier.

TIFF/IT-P2 also TIFF/IT a subset of the specification, including TIFF/IT-P1 all the options, and also supports spot colors, Larger color palette line images, image format screening and more compression methods. Compatible with TIFF/IT-P2 reading program should You can read TIFF/IT-P1 files.

By simplifying and pre-press, printing, document processing and computer graphics industries in many popular software applications supported by the system, Subset restriction function compatible, TIFF/IT-P1 and TIFF/IT-P2 format to make the standard more widely.

1 Scope

This standard specifies the method for prepress electronic data exchange has nothing to do with the media, the method using a Tagged Image File Format. Standards are set Defined image file format capable of continuous-tone color images, color line images, high resolution continuous tone image, monochrome continuous tone images, binary image Like lines and binary image data screening and composite the final page image is encoded.
