IGT Consumables - Shelf Life
When consumables are past their shelf life, there may be a subtle,
slow change in the test results. However this may only become apparent
when replacement consumables are introduced and a noticeable step
change can be seen.
Please refer to the following guidelines on the shelf life of IGT
consumables:
Rubber covered printing discs
Rubber blanket
Use after fitting 6 - 12 months
Shelf life 1 - 3 years
Rubber - coated; non-coated; conventional; UV
Use after fitting 1 - 3 years
Shelf life 2 - 3 years
Top rollers and extra distribution
rollers
Top Rollers
Use after fitting 1 - 3 years
Shelf life 2 - 3 years
Extra Distribution Rollers
Use after fitting 2 - 3 years (replace with top rollers)
Shelf life 2 - 3 years
If the inking system is used extensively, it is recommended that
a replacement regime be established, to ensure an even distribution
of small changes in materials through the year. eg: one of the top
rollers + a distribution roller changed every 6 months or where
4 discs are used: change one disc every 3 months, or change two
discs every 6 months.
Do not change the discs in the same month as the top rollers.
Packings
Rubber
Use after fitting 3 - 12 months
Shelf life 1 - 5 years
Paper

under optimum conditions - removed from transport packaging and
protective foils; stored in the dark, at laboratory temperature,
away from heat sources and chemicals.
Cleaning agents and cleaning methods will influence the use life.
