Correct storing

All papers produced by Jujo Thermal have a shelf life of two years from the date of production. All guarantees given by Jujo Thermal apply only if the paper is stored and used according to these instructions.

Avoid exposure to direct sunlight and hot and humid environments

All papers will turn yellow with time, especially if exposed to direct sunlight for prolonged periods.

For long-term storage, all papers should be kept in the dark at an average ambient temperature of less than 25⁰c and relative humidity of less than 65%.

Additional instructions for thermal papers

If you are searching for a thermal paper grade for an application where there is a risk of contact with harmful materials or for an application where excellent preservability properties are required, please contact our customer service for assistance in selecting the most suitable paper from our range of durable and extra-durable grades.

JTK thermal papers begin to develop colour at temperatures between 60⁰C and 100⁰C and reach an applicable density at 70–120⁰C, depending on the grade. The paper, however, displays similar signs of development at high temperature or in conditions of high humidity. If the paper is used continuously for more than 24 hours at temperatures of 40⁰C or above, attention should be paid to the ambient temperature and humidity.

The printed image tends to fade in direct sunlight.

The image shows a tendency to fade when exposed to conventional fluorescent light for prolonged periods of time. Printed paper should therefore be filed soon after printing.
