The Variable dot thing is pretty easy. Look at the 1, 2, and 3 of each ink color as a progression in dot size with 1 the smallest and 3 biggest. Start off your restrictions with all set to 100. So C1=100, C2=100, C3=100 and so on for each color. Light inks should all be at ZERO.

Use the EyeOne to determine max chroma (saturation) for each full color ink. Then take the value you find from the test print and consider that a percentage of 300 (100 of each dot size). Remove ink starting from the 3's and then progress into the 2's, then the 1's if needed.

Example... let's say you determine you like 65% cyan from the test chart. 300 x .65 = 195. So C3=0, C2=95, C1=100.

Then set the light inks as a 90% progression from the dark ink's 1 value. IOW, if C1=100, lc3=90, lc2=82, lc1=74.

Hope this helps.

If you're faced with a sliding scale for dot size like in Onyx 6.5, leave it at the default middle position and you'll get great results.
