Operation principle
Direct thermoprinting creates display by selective heating and cooling of small elements in the thermal printing head which contact to the paper covered with a chemical layer.
During heating paper darkens that provides contrast of characters of the shaped code. This method thanks to control of the computer of heating elements has a possibility of flexibility when choosing the sign of the shaped code and its printing with a big density and clearness. This method of printing permits to change a format and contents of the label quickly. A lack of a method of thermoprinting is that the light surface of paper sometimes darkens under the influence of temperature or a daylight and the bar code mark loses quality.
