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 colour outputs, customary direct thermal printers lack this functionality.
The capability to supply colour photographs with thermal switch strategies expands the purposes of thermal printing past primary labeling and receipt technology. This broader utility encompasses areas resembling high-quality photograph printing, detailed medical imaging, and sturdy barcode technology. The prevalence of monochrome direct thermal printing stems from its simplicity, velocity, and decrease price in comparison with colour alternate options. Nevertheless, the demand for colour output inside numerous industries continues to drive the event and refinement of colour thermal applied sciences.
