Thermal Printing
Thermal printing is a printing method that uses resistance to increase the temperature and melt ink onto plastic (ribbon) or to print directly onto paper.
This is done using a thermal print head.
What is a thermal print head?
A thermal print head is a key device used for the printing part of thermal image output equipment.
The thermal printing method is used for printing labels and receipts in retail stores, logistics, food barcode labels, ID cards, airline and train tickets, X-ray films, and printing food production dates.
A thermal print head consists of multiple heating elements (heaters) aligned on a heat storage layer (enamel).
It is a device that prints by transferring the heat generated by the flow of electric current through the heater to the printing medium (thermal paper or ink ribbon).
In essence, the heater works like a light bulb.
If there is a ribbon, it is called THERMAL TRANSFER (TT);
if there is no ribbon, it is called DIRECT THERMAL (DT).
Descriptions of Terms
- Dot Density
Describes heater density.Mainly showed;Dots per 1mm. [dot/mm]Dots per 1inch. [dot/inch = dpi]
- Dot Pitch
Describes the distance between each dot.The reciprocal of the dot density.EX) Dot density 8dot/mm = 1/8 = Dot pitch 0.125mm
