Ken,
The reference images offer a uniform method to evaluate output from
different devices. They provide a visual method of comparing
different output presentations (to this standard set of images).
They can be purchased in US or through ISO. Some of the images are
used in the GRACoL Test Sheets and have been very helpful in offering
a reference point for comparing images (especially between proofs and
final printing).
For more details on methods for visual evaluation or a HOW TO on
calibration of output --for matching your file contents between
monitor proof, hard copy proof and then final printing, go to:
www.gracol.org.
In Latin America, we are creating the Spanish equivalent in GRACoL
publications, plus consulting and technical help: Anyone interested
can visit GRACoL Latin America booth during GRAPHICS OF THE AMERICAS
in Miami Beach, March 2-4, 2007. Or they can contact me:

Subject: ISO 12640-2:2004
Has anyone used the images from ISO 12640-2:2004 for evaluating color
profiles? What do you think of them?
ISO 12640-2:2004
Title:
Graphic technology - Prepress digital data exchange - Part 2: XYZ/sRGB
encoded standard colour image data (XYZ/SCID)
Abstract:
ISO 12640-2:2004 specifies a set of 15 standard colour images
(encoded as
both 16-bit XYZ and 8-bit RGB digital data provided in electronic data
files) that can be used for the evaluation of changes in image quality
during coding, image processing (including transformation
compression and
decompression), displaying on a colour monitor or printing. They
can be used
for many graphic technology applications such as research,
development,
product evaluation, and process control.
Thanks!
Ken Fleisher
