There are other coatings that have particular impact on various roll applications. These are known as “active” coatings. The most common is known as “thermal.”
Direct thermal is a specialty form of ribbonless technology. It utilizes a heat-sensitive coating that, when brought in contact with a thermal printhead generates a deep black or in some cases a color image.
Thermal printers and papers come in a variety of heat sensitivities designed for specific applications.
Few moving parts in the printer minimizes trouble issues.
No variation of image from beginning to end of roll.
Maintenance cost and cost of replacement printheads low.
Maintenance time minimized.
Will perform in any climate or atmosphere conditions as long as paper is enclosed.
