I am trying some odd things with inks that lay down a great deal of ink.
Don't ask why <G>.

Two questions-

Is linearization iterative? In other words, will additional
linearizations over a previous fine tune it, or will any linearization
always be a correction from the "native state"?

If one enters a gamma of something other than 1 in the gray curve
section to initially bring things more in line, will linearization
correction include that gamma assuming the setting remains the same
from there on out?

Thanks,
Tyler
