Hi Roger
Yes, you are correct in your thoughts, the TVI curves are the same for all
colour in the 2013 version.

While reviewing the latest ISO-12647-2 standard, I was stumped by the
absence of an explicit specification for each process color "dot gain"? I
have read and re-read and re-re-read each relevant sections of the standard
to no avail? All there "seems" to be are references to the shape of the
curves and the polynomial used to determine the TVIs (shown in Table 9) but
nothing to the effect that there ought to be different aim values for each
process colors? I am tempted to conclude that the specified TVI numbers are
"common" to all four colors? But I hate to come up to that conclusion on my
own.
