The same phenomena is for the Epson and for the Sherpa.
The inkjet yellows are often orange and less vibrant than offset yellow ink.
In fact you'll never get to the extremities of the yellow press ink with any
inkjet that I know of.
Trick is to linearize before profiling to avoid this 100% heavy inkjet
yellow. Then the profiling application should correct out the colour
imbalance. That's the goal , and that is exactly what is achieved when
correctly applying these profiles. Be aware that the Agfa CMM doesn't
correctly do absolute conversions for proofing so your best off choosing
another CMM.
