Shelf Life: The inks and medium of this series have, under normal conditions, a shelf life of at least 6 months.
Normal Conditions means:
- Storage in tightly closed containers.
- No admixtures.
- Short time excessive-temperatures e.g. at transport are not harmful.
- The products are not sensitive to frost.
Over-stored inks stored inks (typical symptoms: Shift in shade, formation of odour and / or viscosity Increase) may normally – (off color being exceptions) - be used the same way as residual inks by controlled admixture to fresh inks. Increased viscosity due to long-time storage of inks may generally be adjusted by addition of a slightly higher amount of thinner than the usual.
