[ECI-EN] Re: Cyan ink ISO Lab values not correct

Hello Is anybody seeing this issue? When using the Lab values to process control a press to ISO 12647/2-2004 I have found, on a number of occasions, that the cyan ink is 4 to 8 delta E out. The other process colours are usually below 2. These are ISO standard inks from major manufactories. I am controlling the process with an GM SpectroEye, using the BestMatch function, and the ISO data as the reference. I am then checking the process colour differences using Alwans Color Pursuit colour workflow analyse tool. Are these figures for the cyan ink common, are they acceptable. I do not think so on a 'blue'.
