The modern day applications of the thermal roll labels are something to talk about, going by the increasing demand of these labels due to the long-term benefits provided by it. The thermal roll labels are cost effective and have good competency. These labels are used in a variety of applications such as cash registers, bar codes and price tags, where information required is to be processed without any delay. In addition, these labels are used for purposes such as packaging information, and even on VHS tapes, part bin, shelves and diskettes.
Thermal roll labels are more reliable and user friendly as they usually have a protective coating around them, thus preserving important data for a long time. Today, these labels are commonly preferred over ordinary labels, as problems with regards to printing by thermal printers do not occur with these.
The basis of a thermal roll label is the thermal paper itself. The paper used is essentially of two types- direct thermal paper and thermal transfer paper. Both these papers can 感熱紙 be identified because of the technology involved in producing them. The dye used in the printing of the direct thermal paper rolls gives a traditionally black color when exposed to heat and due to advancement in modern technology; the thermal paper can also print different colors today.
While using the method of the direct thermal paper, a color change is witnessed during the process of heating up of certain parts of the paper. This direct thermal paper is coated with wax and resin on one side in a manner in which the characters are visibly seen, on heating. On the other hand, thermal transfer paper needs a ribbon and heat to transfer ink on it for the production of characters.
