Thermal Papers

Thermal papers are those that receive a coating layer on their surface that makes them sensitive to heat. As a result, the thermal printing system does not require any ink in the printer, as it is directly applied to the paper. The image (print) is the product of the reaction between the coating layer chemicals and the heat, which is usually emitted from thermal printers, for which they are designed.

What are thermal papers?

Thermal papers are composed of up to 3 layers of coating, each with its respective function, ensuring proper operation of the system, according to the use of the paper. They are:



Undercoating

First coating layer, consisting of a dye with insulating properties, which concentrates the printer's heat on the paper, thus preventing dissipation into the environment. In addition, it closes up and enhances the surface of the base paper (offset) to receive the thermal layer, which contains the chemicals that cause such reaction.


Thermal

Second coating layer, which contains the chemicals that react to heat and are responsible for producing the image. Such chemicals are, basically, a leuco dye and a developer, which produce a black image.


Overcoating

Some thermal papers have this third and last layer, which forms a film on the surface and acts as a barrier that protects the image from means that can damage it and revert it to the leuco state, such as water, oils, solvents and plasticizers.

Thermal papers are used for several applications such as tax proofs, credit card receipts, bank statements, boarding passes, self-adhesive labels, and lottery tickets. Grammage can vary, such as the type of coating, according to the final application of the product.

HOW THERMAL PAPERS WORK?

  • The printer's thermal printhead is formed by small electric heating elements that transfers to the paper a definite amount of heat, giving rise to a reaction between the dyes and the developer
  • The result of the product is the image on its surface.
