Dwight,

For ink limit, we work with values from experience. It depends on various variables like the used ink, the substrate, the resolution, the printing speed, usage of light inks, ...

We have not yet found an algorithm that calculates it based on the linearized single channels. Hence we use a TAC chart when we have a new combination of parameters. As printed ares above the maximum ink threshold may have "artefacts" that cannot get caught using a spectrophotopmeter, a user has to decide what limit to set. Important: it shall define the maximum TAC that can get printed on that substrate. A further reduction to less TAC should be done when generating the ICC profile.

Happy to hear about other experiences.

best
Peter
