What is the working principle of TTO high-speed coding carbon tape?

TTO high-speed coding carbon tape, the full name of the carbon tape used by the Thermal Transfer Overprinter, its working principle mainly involves the thermal printing technology and the characteristics of the carbon tape material. The following is a detailed analysis of its working principle:

First, Basic composition and material characteristics

The TTO carbon belt is mainly composed of the following parts:

Ink layer: This is the core part of the TTO carbon belt, responsible for printing and determining the characteristics of the use of the carbon belt, such as chemical corrosion resistance and anti-friction. The ink in the ink layer melts and adheres to the printing medium when heated.

PET film: As the carrier of other layers, PET film determines the performance of heat conduction, which has a direct impact on the printing effect. It has good heat resistance and mechanical strength, which can support the ink layer and ensure the uniformity of heat transfer.

Back coating: The purpose of this special coating is to reduce print head wear, reduce static electricity generation and enhance heat conduction. It protects the print head while improving printing efficiency and extending the service life of the device.

Second, the working principle

The working principle of TTO high-speed coding carbon strip is based on thermal transfer technology, and the specific process is as follows:

1.Information generation and editing: First, the content to be printed is generated by software, including Chinese characters, numbers, letters, pictures, etc. These contents can be batch number, group, batch, production date, expiration date, ingredient list, nutrition list, bar code (variable), two-dimensional code (variable), etc.

2.Ribbon positioning and heating: Place the TTO carbon strip between the inkjet print head and the coded product. The inkjet printhead is a highly integrated ceramic-glass assembly containing hundreds of individually controlled micro-heating elements per inch width. These heating elements quickly turn on (heat) and off (cool) after receiving a print command, transferring heat to the ribbon.

3.Ink melting and transfer: Under the action of heat, the ink on the TTO carbon belt begins to melt. At the same time, the print head maintains a certain contact pressure with the coded product surface, so that the melted ink is released from the bottom of the ribbon and adhered to the product surface.

4.Cooling curing: The ink adhering to the surface of the product is quickly cured after cooling to form the content edited by the software in advance. In this way, the thermal transfer printing process from the TTO carbon to the product surface is completed.

Third, Technical advantages and application fields

TTO high-speed coding carbon strip has the following technical advantages:

High-speed printing: Supports printing speeds up to 40inch/sec to meet the needs of fast production lines.

Wear resistance: With good durability, suitable for long-term identification.

A wide range of label adaptability: can print a variety of materials, including coated paper, synthetic paper and packaging film.

Clear image printing: Ensure that the printed content is clearly visible and improve the appearance quality of the product.

Due to these technical advantages, TTO high-speed coding carbon belt is widely used in packaging, identification and product traceability and other fields, especially in food, medicine, daily chemical and other industries are widely used. For example, in the food industry, it can be used to print the production date, expiration date and batch information of soft packaging products such as milk powder, frozen food, candy, biscuits, etc. In the pharmaceutical industry, it can be used to print information such as bar codes and two-dimensional codes on pharmaceutical packaging boxes.

To sum up, the working principle of TTO high-speed coding carbon belt is based on thermal transfer technology, which melts the ink on the carbon belt by heating and adheres to the surface of the product, so as to achieve high-speed, clear and durable printing effect.
