The first for characters, for example AEY0, include the web part page A, the language (G=german, E=english), the image page (A, B, C, ...,Z), and the figure part page (0, 1, ..., 9). Figure 1 shows the figure coding on the left page (0-1, 0-2, ..., 0-8), and on the right page (1-1, 1-2, ..., 1-8). A figure can consist of multiple pages (N or A).
The extension describes the figure format. Vector-graphic files are described with capital characters in the formats PS, PDF, TXT, JPG, and TIF. Pixel-graphic files use small characters for the formats eps, pdf, txt, jpg, and tif.

The input-output relation between CIE lightness L* and 8bit rgb data for slide film (sf) and negative film (nf) is shown between under to over exposure.
3. Device and elementary hue circles, and location in hue circles of LMS cones, and chromatic and chroma data
Figure 3 shows device and elementary hue circles, and hue location of LMS cones (left), and antagonistic and opponent chromatic and chroma data (right).

The location of the cone sensitivities LMS is very different compared to the location of the "sensitivities" RGB which are for example used for scanners and cameras. The reason is up to now mostly unknown.
4. Four device systems ORS18a, TLS00a, FRS06a, TLS18a, and CIE elementary hue data in CIELAB diagram (a*, b*)
Figure 4 shows four device systems ORS18a, TLS00a, FRS06a, TLS18a, and CIE elementary hue data in the CIELAB diagram (a*, b*).

The chroma of the four device sytems is very different. The full names of the device systems are given in the figure. For Blue Bd the two Television Luminous Systems TLS00a and TLS18a have a chroma by a factor 2 larger compared to the Offset Reflective System ORS18a.
Figure 5 shows four device systems TLS27a, TLS38a, TLS52a, TLS70a, and CIE elementary hue data in the CIELAB diagram (a*, b*).

The area of the chroma hexagon decreases with the reflection of the ambient light on the screen surface. The last case may happen with a projector. The luminance by the projector and by ambient daylight is then approximately equal on the sceen surface.
In this case and for the intended equally spaced output of a 16 step gray scale according to ISO 9241-306:2018, the output gamma shall be changed from ga = 2,4 for TLS00a to ga = 1,2 for TLS70a. The relative gamma of ISO 9241-306 is then changed from gP = 1,0 to gP = 0,5. This corresponds to the two ISO-contrast steps CYP8 and CYP1.

6. Input-output relations and user steering of the output on rgb displays and in cmyk print
Figure 7 shows Input-output relations and user steering of the output on rgb displays and in cmyk print.
For the download of this figure in the VG-PDF format, see AEY90-3N.PDF.
Professional printers are often called proof printers. For example for the standard offset printing users can steer the output with cmyk data. Proof printers show the expected offset output with cmyk data in advance.
Similar users can steer the output on all PostScript-printers by cmyk data. Therefore users can apply output linearization with 100% Under Colour Removal (UCR). In this case, for example the gray samples are only printed by the black colorant. This is the ergonomic output according to ISO 9241-306. This reduces the printing costs compared to the case, if achromatic colours are printed by a mixture of chromatic and achromatic printing colours. In addition the important achromatic stability of the output increases.
The so called RGB-printers in the consumer area do not allow to steer the output with cymk data. The change from rgb to cmyk data is under full control of the manufacturers. Therefore users can not produce an ergonomic output by output linearization with 100% UCR.
