 1. AVOID HOT AND/OR HUMID ENVIRONMENTSFor long-term storage, store THERMAL in the dark at an average ambient temperature of less than 25°C and a relative humidity of less than 65%.
THERMAL begins to develop colour between 60°C - 100°C and reaches applicable density at between 70°C to 120°C. The paper, however, displays similar signs of development under high temperature or high humidity conditions. If the paper is used continuously at temperatures of 40°C
or above for more than 24 hours, attention should be paid to the ambient temperature and humidity.
2. AVOID EXPOSURE TO DIRECT SUNLIGHTThe paper will yellow if exposed to direct sunlight for prolonged periods. The printed image
also tends to fade in direct sunlight.
The image tends to fade when left exposed to conventional fluorescent light for prolonged
periods of time. Therefore, printed-paper should be filed soon after printing.
3. DO NOT USE SOLVENT-TYPE ADHESIVESAdhesives containing volatile organic solvents such as alcohols, esters, ketones etcetera, cause color formation.
Adhesives based on starch, PVA or CMC are harmless and hence recommended.
