Hi Paul,
We have just completed ISO 12647 compliance for the TSO (The Stationery
Office) as part of the Pantone Printer Accreditation Program.
We had no trouble achieving ISO 12647/2-2004 I conformance on the cyan. I am
afraid I can't remember the ink manufacturer but if you would like these
details I can get them for you.
Two areas to look at maybe the set up of the SpectroEye and the paper stock.
We have recently had an issue where a slight change in the paper stock has
had quite a dramatic effect on the cyan.
We run regular course on ISO 12647-2 entitled "Using ISO 12647-2 in Print &
Design" which deals with the set up and workflow required to conform to ISO
12647. The next course takes place on 26th & 27th April.
If you need any further help please let me know.
Regards

Subject: [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'.
