Back to CGATS TR 001 - 1995 (R2016) Bundle - Hard Copy
This report provides public access to, and a reference source for, colorimetric characterization data describing offset lithographic printing meeting the requirements of ANSI/CGATS.6-1995, Graphic technology — Specifications for graphic arts printing — Type 1. The input test data is as defined in ANSI/IT8.7/3-1993, Graphic technology — Input data for characterization of 4-color process printing, and all measurements are in accordance with ANSI/CGATS.5-1993, Graphic technology — Spectral measurement and colorimetric computation for graphic arts images. Because the data contained in this report is based on the measurement of press sheets produced by practical printing, the data itself cannot be normative. However, it provides the best estimate of the characterization of this class of printing, and as such it is an important reference. It is expected that the use of this reference data will be a requirement of many printing application programs.
NOTE 1: CGATS TR001 characterization data is based on the SWOP printing aims as they existed in 1993. While these data are still valid, and are used to describe the CMYK to color relationship of many CMYK data files, for newer work they have been superseded by CGATS TR003 and CGATS TR005. These newer data sets represent SWOP proofing and printing on U.S. Grade 3 and Grade 5 coated publication paper respectively.
NOTE 2: TR001 contains colorimetric characterization data describing offset lithographic printing meeting the
requirements of the now withdrawn CGATS.6. It is now provided for historical traceability of standardized
publication printing. For values and guidance for current publication printing aims please refer to CGATS.21
series or the ISO equivalent, ISO/PAS 15339.
