Thermal labels are those labels produced using thermal print methods. Thermal printing has long been a favourite due to its speed and low cost. There are basically two means by which one can produce thermal labels. Let us look at both systems.
Before we begin, however, it may make some sense to discuss the ways in which the two systems are similar. Both use a thermal print head. That head applies heat to the surface that will be labelled.
With thermal transfer printing, a heated ribbon is used. The result is a very solid and long lasting image that can be applied to a variety of different products and surfaces.
With direct thermal printing, no ribbon is used. Instead, the label upon which the printing is to occur is specially treated with a substance. This system can produce a clean image, but light and heat sensitivity often create problems and the life of the resulting label may be cut short.
Either system can produce great-looking thermal labels. However, direct thermal printing, due to its reliance on the treated paper and its susceptibility, is usually only used in situations where permanence is not a factor and the labelled product will not be exposed to extreme conditions.
Thermal printing is an interesting process that uses a special print head and either a treated ribbon or a special kind of paper. These systems have long been used because of the clear images they produce and the relatively low cost associated with creating thermal labels.
If you are looking for a label production strategy, thermal labels may be just what you need. If long term quality will take a backseat to speed and savings, take the time to investigate thermal labels.
