Thermal Paper/ Thermal Label
Thermal paper is a special fine paper that is impregnated with a chemical that changes color when exposed to heat. It is used in direct thermal printers and particularly in cheap, lightweight devices such as cash registers, POS, ATM and credit card terminals. The coating will turn black when heated. But coatings that turn blue or red are sometimes used.
*The pigmented pre-coats that are applied to the base paper are a feature of thermal papers, They are vital if the thermal coat on top is to work perfectly. The thermal coat contains the chemical components that generate the image through point heat transfer by the thermal printer. Further protective coatings on the front and back give the thermal coat additional protection against chemical influences and optimize the properties of the product with regard to a wide variety of specific requirements such as printability, lamination, etc.
Most direct thermal papers require a protective coating to:
For every grade of thermal papers, it grant a certain life span for the thermal image. The lifespan of the thermal image is based upon a set of optimum storage conditions and a fully developed thermal image. Under these conditions a thermal image will last anywhere between 1 year up to 25 years depending on the grade. The reality of day-to-day use is that thermal paper is not stored in perfect conditions. The paper is often subjected to conditions that can be destructive to the thermal image and/or image contrast. It is therefore important that a suitably stable grade be selected for the end application.
As with office paper, thermal paper should be stored indoor, at temperatures between 18°C and 24°C and with a relative humidity of 40% to 60%. Storage of un-imaged thermal paper under these conditions will assure satisfactory performance for at least 3 years from the date of manufacture. Longer term storage at temperatures over 40°C or over 65 relative humidity can lead to a reduction in image contrast or performance of the thermal function.
Direct sunlight, fluorescent and similar UV light sources should be avoided. As the contrast of the printed image can be reduced or destroyed depending on the duration of contact, thermal paper should not come into contact with,
