Title: CIELAB and IECsRGB colourimetry and colour appearance
adjacent and separate 9 step grey scales.
production of visual equidistant grey steps
1. Introduction and goals;
2. CIELAB snd IECsRGB colourimetry and colour appearance;
3. Adjacent and separate 9 step grey scales;
4. Production of visual equidistant grey steps;
5. Application of visual evaluations with software products;
6. Applications and discussion.

The following ten pages hea0 to hea9 of this chapter
show the content with links to the single figures in up to six formats.
