Thermal Label Catalogue FAQ
What are direct thermal labels? +
Direct thermal labels are paper rolls coated with a heat-sensitive layer. When passed through a direct thermal printer, heat from the printhead creates high-contrast black text, barcodes, and graphics without ink, toner, or ribbon.
Do thermal labels need ink? +
No. Direct thermal labels require zero ink, toner, or printer ribbons. The printing mechanism is entirely heat-based.
What is a 4x6 thermal shipping label? +
A 4x6 thermal shipping label measures 4 inches wide by 6 inches high (100mm x 150mm). It is the standard official shipping label format required by Royal Mail, DPD, Evri, Amazon, and DHL.
Are 4x6 labels the exact same as 100x150mm labels? +
