Thermal paper is subject to fading with time, humidity, and exposure to light.
It is the manufacturer's recommendation that thermal paper be stored in a dark
place with an average ambient temperature of less than 77 °F (25 °C) and a
relative humidity less than 65%. Under these conditions, the paper remains
readable for at least five years. It is recommended that if the printed data is to
be retained for periods of time longer than five years (6 to 25 years), an
additional photocopy should be made for record retention. In any case, a
duplicate set of records should be maintained in the files of the engineering or
maintenance departments.
Thermal paper begins to develop color at about 158 °F (70 °C), however,
under humid conditions, it might begin to develop at an accelerated rate. If
stored for 24 hours at 140 °F (60 °C), the paper will show some signs of
development. It will also show signs of development if stored for 24 hours at
113 °F (45 °C) and a relative humidity of 90%.
Do not store thermal paper next to other chemically treated papers - such as
pressure sensitive paper or other type of recording round charts - as this may
cause fading in print. If thermal paper is to be stored in the same area, always
ensure it and other chemically treated papers are kept in separate envelopes.
Thermal paper discolors when exposed to direct sunlight.
