6.7.3 Store Thermal Paper Thermal paper is subject to fading with time, humidity and exposure

to light.

It is 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, 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 (6-25 years), an additional photocopy should
be made for record retention. In any case, a duplicate set of records
should be maintained in files of 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), 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 same area, always ensure it and other chemically treated
papers are kept in separate envelopes.

Thermal paper discolors when exposed to direct sunlight.
