Yes it was a NGen based inkset.
In general, even highly pigmented inkjet inks are always quite transparent (exept black and white).
I didn`t print the yelleow lgend over the darker area, but printed it all toghether in a single step - the printfile of the soldermask included the legends.
The different shades within the legends are because of the different colors of the material below - copper and the FR2 base material.
For a better readability, I`ll do some boards with yellow soldermasks including black legends.
I `d say its a benefit of this inkjet-process that soldermask and legend printing can be done as a one-step process.
