Direct thermal labels are the product of the direct thermal printing process. Unlike most other means of printing, the direct thermal strategy does not rely on any toner or ink.
Instead, a heated printhead is applied to label constructed of a specially treated type of paper. This paper reacts with the precise printhead to bring out images quickly and clearly.
Because direct thermal labels bypass many of the expenses associated with other print techniques and do the job much faster than ink-based systems. As such, thermal labels produced with this method have a loyal fan base.
There are, however, weaknesses in direct thermal labels. The treated paper cannot distinguish one source of heat from another. Thus, exposure to hot conditions or to direct sunlight can deteriorate, if not ruin, a labels.
Thus, many of those who like direct thermal labels work in a situation where labelling needs are relatively temporary on any given product or where they are certain the products will never experience a significant environment saves.
If you need relatively inexpensive thermals labels in a hurry, direct thermal printing may be the perfect solution for you. It may not be the best means of handling some types of printing jobs, but those it does handle it handles quite well.
