If the ink solvent exceeds its shelf life, adverse chemical changes will occur, such as: 1. The conductivity is reduced, the ink droplets cannot fully absorb electricity, and the printing is intermittent; 2. Cause the formation of insoluble impurities, block the ink path and nozzle of the inkjet printer; 3. The viscosity of the ink changes, aggravates the blockage, and the printer fails and stops. These changes can cause reliability issues with the printer and also lead to a deterioration in print quality. Due to the unpredictable nature of these changes and their potential harmfulness, they can affect the performance of the printer and accelerate the aging of the printer. Therefore, do not use inks and solvents that have exceeded their shelf life.

The performance of coding solutions in the wire and cable industry needs to match the actual production process. Printer downtime interrupts the extrusion process, resulting in costly downtime, rework, and scrap. In addition, poor coding contrast or quality and ink transfer can also reduce product quality. General cables require high adhesion professional ink, clear reading, durable coding, diverse and flexible coding content, high speed, stability, and accurate meter counting Meet the high ink adhesion requirements of PE and PVC and low-smoke halogen-free cable materials, with good high temperature resistance, water resistance and scratch resistance, and good light resistance, regardless of cold and heat, lightning and rain, the cable mark is still firmly attached to the surface material. Flexible printing formats for high-quality and versatile coding effects; Support multi-language, provide date, text, barcode and two-dimensional code and other printing content, and the data can be modified and saved at any time, without stopping the production line; Provide a variety of dynamic anti-counterfeiting code solutions for cable coding. Technical specifications: main technical parameters and characteristics (1) The nozzle uses patented technology, and the recovery hole automatically moves the sealing nozzle when the machine is turned off, so that the ink is retained in the pipeline to form an internal circulation, and the air and dust in the pipeline are not easy to block the nozzle, making it easier for the operator. (2) When printing, the inkjet printer needs to be cleaned, the inkjet printer has the function of compensation for the number of stop meters, such as: printing to 100 meters needs to be stopped, during the shutdown after 50 meters, when the printer resumes operation, it will start printing from 150 meters.

Invisible ink inkjet printer does not refer to the ink is really invisible, but will not be displayed under normal light, only through the ultraviolet lamp after the character formed by the ink can be seen, with better anti-counterfeiting. Invisible inks, also known as "fluorescent inks", are generally available in small character inkjet printers or high-resolution inkjet printers.
