Conventional thermal printing depends on heat-sensitive paper reacting to a print head, producing a monochrome picture, usually black. Whereas specialised thermal switch strategies exist, using a ribbon coated with coloured wax, resin, or ink to create coloration outputs, commonplace direct thermal printers lack this functionality.
The capability to supply coloration pictures with thermal switch strategies expands the functions of thermal printing past fundamental labeling and receipt era. This broader utility encompasses areas corresponding to high-quality picture printing, detailed medical imaging, and sturdy barcode era. The prevalence of monochrome direct thermal printing stems from its simplicity, velocity, and decrease price in comparison with coloration options. Nonetheless, the demand for coloration output inside numerous industries continues to drive the event and refinement of coloration thermal applied sciences.
