In the era of widespread use of thermal printing, large thermal printing ribbon plays an important role in logistics, retail, medical and many other fields with its high efficiency and convenience. However, the anti-fading performance of the ribbon has always been a key factor affecting the printing quality and long-term preservation of information.
There are many scientific methods to evaluate the anti-fading performance of large thermal printing ribbon. First, the accelerated aging test is used to place the ribbon in extreme environments such as high temperature, high humidity, and strong light to simulate the state after long-term use, and the degree of fading is evaluated by regularly observing the color changes of the printed content. Second, a professional colorimeter is used to measure the color parameters of the printed content at different time points, and the fading is quantified with objective data. Third, a real-scene test is carried out to place the printed labels or tickets in the actual use environment and observe their fading performance over a certain period of time.
There are many factors that affect the anti-fading performance of large thermal printing ribbon. The formula and quality of the thermal coating are the key. High-quality coating materials and reasonable formulas can enhance the stability of the dye and reduce the possibility of fading. Printing temperature and time will also have an impact. Excessive temperature and excessive printing time may cause excessive reaction of the dye and accelerate fading. In addition, environmental factors such as light, humidity, and temperature will also have a significant impact on the anti-fading performance of the ribbon.
Starting from the material aspect is an important way to improve the anti-fading performance. Develop new thermosensitive dyes to improve their thermal stability and light stability, so that they are not easy to decompose under high temperature and light conditions. Optimize the coating formula, add antioxidants, UV absorbers and other additives to enhance the protective effect of the coating and reduce the damage to the dye by external factors. At the same time, improve the quality of the substrate, select aging-resistant and corrosion-resistant substrates to provide better support for the coating.
Reasonable printing process is crucial to improve the anti-fading performance. Accurately control the printing temperature and time to avoid excessive reaction of the dye due to excessive temperature and excessive printing time. Adjust the pressure of the print head to ensure the printing quality while reducing damage to the ribbon. In addition, regularly maintain and calibrate the printing equipment to ensure the accuracy of the printing parameters.
Improving the storage and use environment of the ribbon can also effectively improve its anti-fading performance. Store the ribbon in a dry, cool, light-proof environment, avoiding direct sunlight and high temperature and humidity. During use, try to avoid contact between the ribbon and chemicals to prevent chemicals from damaging the coating.
The anti-fading performance of the ribbon can be enhanced by using surface treatment technology. For example, a protective film is applied to the surface of the ribbon to isolate the influence of factors such as air, moisture and light. Or the surface of the ribbon is specially treated to improve its wear resistance and chemical corrosion resistance.
Formulate strict industry standards to regulate the production and quality inspection of large thermal printing ribbon. Enterprises should follow industry standards to ensure that the ribbons produced have good anti-fading performance. At the same time, strengthen market supervision, crack down on counterfeit and shoddy products, and protect the rights and interests of consumers.
Improving the anti-fading performance of large thermal printing ribbon requires starting from multiple aspects such as materials, processes, environment, and technology. Through the application of comprehensive measures, the quality and performance of the ribbon can be continuously improved to meet the needs of different fields for printing quality and long-term preservation of information.
