What is the printing principle of TTO high-speed coding ribbon?

The printing principle of TTO high-speed coding carbon tape is mainly based on thermal transfer printing technology. The following is a detailed explanation:

1、 Basic definition

TTO is the abbreviation for Thermal Transfer Overprinter in English, which stands for Thermal Transfer Printer. TTO high-speed coding ribbon is a key consumable used in this technology, which is a printing consumable specifically designed for use on heat transfer coding machines. This type of carbon ribbon is usually coated with mixed, high-grade mixed, or resin based ink on one side, and lubricant on the other side to prevent wear of the print head.

2、 Printing principle

Heat transfer printing process: During the heat transfer printing process, a carbon ribbon is placed between the print head and the printed object (usually flexible packaging materials such as film, plastic bags, composite films, etc.). The print head transfers heat to the ink layer of the carbon ribbon through a rapid heating and cooling process, causing the ink to melt and release from the bottom of the carbon ribbon, adhering to the surface of the printed object.

Software editing and precise control: The printed content (such as text, barcodes, images, etc.) is pre edited through software. During the printing process, the print head will precisely control the opening and closing of each heating element according to software instructions, thereby achieving high-precision printing effects.

High integration nozzle ribbon module: TTO thermal transfer printers are typically equipped with highly integrated nozzle ribbon modules, which include multiple independently controlled micro heating elements (such as 300 independently controlled elements per inch width) to ensure the clarity and accuracy of printed content.

3、 Printing mode

Continuous mode: suitable for continuous production lines, performing heat transfer printing and coding on moving products. At this point, the substrate (the product marked with the code) continues to move, while the print head remains in the left and right positions and moves up and down. This mode requires a synchronizer to ensure synchronous movement between the print head and the substrate.

Intermittent mode: suitable for intermittent printing on production lines, completing printing work during stationary periods. At this time, the substrate undergoes intermittent motion, and when the substrate stops moving, the inkjet printer head moves on the substrate. This mode requires auxiliary equipment such as silicone pads to ensure printing quality.

4、 Application fields and advantages

TTO high-speed coding ribbon is widely used in flexible packaging products in industries such as food, medicine, and daily chemical products. It is used to print production dates, batch numbers, ingredient lists, nutritional content tables, company logos, barcodes, and other information. Its advantage lies in the ability to achieve high-precision and high-definition printing effects, while ensuring the durability and reliability of printed content.

In summary, the printing principle of TTO high-speed coding ribbon is based on thermal transfer printing technology, which transfers ink from the ribbon to the printed object through precise heating and cooling processes, thereby achieving high-quality printing results.
