Why do Images Fade on Thermal Paper?

Since standard POS grade thermal paper is sensitive to ultraviolet light, it must be stored properly to encourage fade resistance. Thermal documents should be stored in a dark place at a relative humidity between 45% and 65% and a room temperature below 77°F (25°C). If these conditions are met and the recommended equipment is used to create the thermal documents, the images should remain legible for at least five to seven years.

In addition to UV light, exposure to the following materials may lead to image degradation and should therefore be avoided:

• Organic solvents (i.e. Alcohols, Ketones, Esters, and Ethers)
• Cleaning Fluids
• Plasticizers
•  Petroleum Solvents
• Wet-type diazo copy paper
• Carbon papers
• Castcoated papers
• Papers containing tributal phosphate
• Dissimilar thermal systems
• Carbonless papers
•  Ammonia
• Certain Oils
• Water (prolonged exposure)
