Measure - InkCheck (ExPresso Pro)
Densitometric values are a direct measure for the ink applied on the paper.They
are very process-related, although they are relative values only. Colorimetric values
as recommended in print standard ISO 12647 are absolute values, but they are not
suited to use them for handling the printing process.The very useful "InkCheck"-
function combines the best of both worlds: Spectrally based recommendations how
to set the ink keys as used from density in order to meet colorimetric targets
required for printing within ISO standards.
Example:
In this case there is not enough yellow ink applied in ink zone 8.
In order to achieve a lower ∆E, the density has to be lifted by 0.07 to D=1,30.
