  By taking into account the properties and limitations of the human visual
system, images can be more efficiently compressed, colors more accurately
reproduced, prints better rendered. To show all these advantages in this paper
new adapted color charts have been created based on technical and visual image
category analysis. A number of tests have been carried out using extreme images
with their key information strictly in dark and light areas. It was shown that
the image categorization using the adapted color charts improves the analysis
of relevant image information with regard to both the image gradation and the
detail reproduction. The images with key information in hi-key areas were also
test printed using the adapted color charts.
