The aim values in ISO 12647-2 are Lab values (not densities anymore). You
(or your customer) will have to make test print runs with varying
densities, measure the appropriate patches and find out which density
value come closest to the Lab aim values. Those density values will be
the right ones for doing process control (i.e. these are _your_/_your
customer's_ density aim values) on that specific press setup, using those
specific inks on that specific substrate.

Well, one of my customers, it's going to print a
test job with some images
like the Altona test suit ones, some special color patches, an ECI 2002
color chart, but his question is: Witch are the standard densities to print
with UVI inks on polypropylene and PVC medias?, is there any ISO applicable
to the packaging sector?.
Best regards.
