I belive the TVI is supposed to be 14%@50 with a 150lpi

should first have a curve to make your plate linear, then a
calibration curve to achieve DG14%. The ISOCoatedV2_ECI the DG is
based on printing with DG14% (CMY).
You have to be aware that (sometimes) it's pretty difficult to obtain a very
straight linear plate and a very precise curve for your tonal correction.
Sometimes the addressebility (lightsource spot and resolution ratio) and
peaks are difficult to control. In the end it's more important that you get a
correct end result. The Fogra tools to check your CTP are important.
Fogra's warnings on the subject linear/tonal are (sometimes) even more
important.
