Color Tone Value - CTV by Aptec

[DeltaE]

Hi Experts,

Does anyone know or hear about the CTV (Color Tone Value) calibration process?
Please explain or share any idea about it if you know!

Thanks in advanced!

Can you provide more context?
Is this in regard to Idealliance's G7 method?
Measuring the dE at the 50% screen tint?

I do not know how it is, that is why I am here for asking for any explanation!
all I know that is they adjust TVI and care about color value of tonality at the same time!

There is some info on the APTEC site (I translated in Chrome). It appears to be referencing SCTV and possibly applying that to 4/c printing, and they have released an characterization data on CCNB at icc.org. (which is 4/c)

Hi Bret,

I had read these information before, but what I need to know that someone who is actually working on/with this kind calibration, share some idea or any insight about it.
As I know, there are some printers in China and Hongkong which has chance to try and work on it, but no more information.

I am not sure it could become a new trend like G7 process or not, as it has been advertised by Aptec with some advantages, then I thought it could show some prospect in future.

Thanks and best regards,
DeltaE
