By: Press Release | NPES

Reston, VA—Providing a reference of color images in electronic form for research, testing, and assessment of output systems (including printers, color management systems and color profiles), the International Organization for Standardization Technical Committee 130 (ISO TC130) has published ISO 12640-4 Graphic technology–Prepress digital data exchange–Part 4: Wide gamut display-referred standard colour image data [Adobe RGB (1998)/SCID].

This part of ISO 12640 provides a reference set of wide gamut display-referred color images in electronic form, encoded as 16-bit Adobe RGB (1998) digital data, that can be used to evaluate changes in image quality during coding, image processing (including color re-rendering and color space transformations, compression and decompression), displaying on a color monitor and printing. The images of Part 4 supplement the images of Part 1 (CMYK data), Part 2 (sRGB gamut images), and Part 3 (large gamut images encoded as CIELAB data). Part 4, available on DVD, includes 14 natural images and two synthetic images (test charts).

ISO 12640-4 is available for purchase from NPES and ISO member national organizations. For more information or to order, visit the Standards Workroom or contact Debbie Orf, NPES Assistant Director of Standards, at phone: 703/264-7229 or e-mail: dorf@npes.org.
