Although the dot area and TVI are not reliable for controlling color reproduction, for offset presses, they can still be used to control chroma.
After reaching the standard solid ink density, check the TVI to ensure that each color is printed correctly. In addition, the adjustment of the curve can solve some physical or chemical phenomena (abnormal phenomena) on the printing press.
In operation, if the color problem cannot be solved by SID adjustment, the TVI ink value can indicate which color printing or printing errors.
Monochrome TVI ink values ​​should also be controlled, as should gray balance, HR, as part of the overall process control.
On some stable devices, single chromaticity and overprinting are well foreseen. It can be used to understand the CMY TVI value of the device. If it is measured one by one, the device gray balance and NPDC can be controlled. But this does not work on offset presses, and does not dominate in the reading of gray blocks.
