ISO 12647-2 2004 TVI on ISOCoated_v2_eci.icc

I want to obtain ISO 12647-2 2004 TVI curve that I have some questions?

  1. where can I obtain ISO 12647-2 2004 TVI points
  2. Can I obtain TVI points in ISOCoated_v2_eci.icc
    Example: from CMYK to obtain Lab in icc profile and then convert to XYZ then using formula to calculate densities

thanks

Hi Master,

Thanks for replying about my question.

But I still have some questions about that.

My purpose is using TVI to deal with color calibration. I referred to some applications that using ISO 12647-2 curves A (CMY) and B (K) as target.

So I asked how to obtain the points of ISO 12647-2 TVI for calculation between target and sample.

I try to obtain the points of TVI curve using ICC-Profile, but these TVI points are difference from ISO 12647-2 curves A (CMY) and B (K).

So I get confuse which points are correct for color calibration.

How do you pull-out TVI values from an ICC profile???
