Care of recording paper
While unopened, thermal paper will not be affected by the
environment, provided that ambient temperature and
humidity do not exceed normal levels. For long-term
storage, temperature should be lower than 40
(104 ).
Low temperatures cause no problem.
After opening, protect the paper from strong light, to prevent
discoloration.
Storing data
The recording paper uses a thermochemical reaction.
Note the following points:
To avoid discoloration, do not leave recording paper in
direct sunlight.
Store at not more than 40 (104 ) and 90% RH.
To keep definitive data, make photocopies of the recordings.
Thermal paper will blacken when brought into contact with
alcohol, ester, ketone, or other volatile organic substances.
If the thermal paper absorbs an organic solvent such as
alcohols or ketones it may no longer develop properly, and
recorded information may fade. Soft PVC film and
transparent contact adhesive tape contain such solvents, so
avoid using them with recordings.
Avoid interleaving the thermal recordings with damp diazo
copies.
