The prints on thermal paper fade over time, and faster with exposure to light, particularly ultraviolet light, as well as other chemicals. The stability and longevity of prints depend on how they were developed, the materials used, the type and intensity of the substance to which they were exposed. To keep cash machine roll in good condition, they must be stored in a dark storage in relative humidity of 50 percent and room temperature of below 77 degrees Fahrenheit. Given that the development and the materials used for making the prints are ideal, the prints should last up to 7 years.
Thermal till rolls comes in varying grades. Grading takes into consideration four aspects, namely sensitivity, environmental resistance, longevity, and calliper. Sensitivity refers to the amount of energy or heat needed to make prints. This means that the paper with higher sensitivity makes finer, better prints. Environmental resistance refers to the paper’s level of resistance against destructive elements like light, heat and moisture. Thermal rolls mustn’t be exposed to substances such as cleaning fluids, solvents, water, ammonia and oil, among other things to avoid degradation.
Longevity refers to the number of years the prints on the paper is guaranteed to last. This period however is shortened when the thermal paper isn’t stored properly. Calliper refers to the thickness of the material measured in mils. To know which grade of till paper to buy, determine your application needs. If you want the prints to last for a long time, buy paper with high grade. On the other hand, consider the quality of prints or images you want to make. Crisper prints are achieved using paper with high sensitivity.
Speaking of sensitivity of paper rolls, high sensitivity paper is best when dealing with bar codes, thermal tickets, ATM receipts, and parking receipts. Alternately, use low sensitivity paper when making standard sales receipts, weight labels for supermarket products, and logistics tags. If you’re using speed printers, high sensitivity paper is suitable for fast speed printing whilst low sensitivity paper is great for standard speed printing. When the printing environment is exposed high temperature or UV light, choose paper with static sensitivity to get good thermal images.
Overall, the quality of paper you use affects the quality of prints or images you create. Nevertheless, you also have to factor in the quality of your printer and the condition of the printing environment. Familiarise yourself with your printer specifications to understand the grade of thermal paper that best works with it. Finally, avoid producing prints in extreme conditions unless you’re certain of the performance of your paper and printer. In regular environments though, standard paper and printer works just fine.
