FAQ
What is a Thermal Paper?
Thermal paper is paper that has been pre-coated or impregnated with special chemicals that react with heat at a specific temperature. When the thermal paper passes over the print head in a thermal printer, the areas in direct contact with the print head turn black producing an image. Text, images and barcodes can be produced on thermal paper at very fast speed
How long does the Image Printed on Thermal Paper Last?
Our premium quality thermal paper rolls provide an archive ability of about 3~5 Years. However to ensure longer image retention of your thermal printouts, don't store them in plastic. Plastic coverings can react with the printed image and cause it to fade at an accelerated rate.
What are Top Coated Thermal Papers?
These are Special Thermal Papers with a special additional coating. The coating provides a protective layer, providing excellent resistance to moisture, grease and solvents etc., thereby ensuring longer print retention of the Image.
What kind of Things can be printed on Thermal Paper Rolls?
Company logos, promotions, advertising, special offers, discount coupons etc. can all be printed (Front Coated Side or Reverse Uncoated side) on most types of Thermal Paper Rolls. We can print these in Single or Multi Color as per customer request subject to minimum volumes.
What are the important characteristics of Thermal Papers?
The main function of thermal paper is “THERMAL PRINTING”. This is why, in addition to normal paper properties like grammage, thickness, Opacity, Strength etc., the thermal printing quality and the image stability are most important as far as Thermal Paper is concerned.
How do we rate Thermal Paper Properties?
The thermal printing property can be divided into “DYNAMIC SENSITIVITY” and “MAXIMUM DENSITY”. The dynamic sensitivity shows how fast and with lower energy the thermal paper can be printed whereas higher maximum density can give the distinct thermal printing image, good readability, and strong image stability.
Why does Printed Thermal Paper fade over time?
The image which develops on thermal paper is produced by a chemical reaction between color-forming substances and color developers. This chemical reaction can undo itself over time, since the dyes tend to revert to their original state – white, that is. Plasticizers, oils, sunlight and liquids can speed up fading process. The image stability of a thermal paper can therefore only be ensured if handled and stored in the way specified by the manufacturer.
