Shelf life of Pantone inks

[Alien]

Dear all,
what is shelf life of Pantone inks for sheetfeed offset?
Especially interested in neon series (e.g. Pantone 805C).

I would say 6 months to 1 year for fluorescents such as 805. The fugitive dyes will have a tendency to diminish with time.

UV curable inks would be 1 year.

Regular oil based inks can be 5 years. Be more careful with blacks as the carbon containing ink can absorb the driers and effect drying.
