Paper water-based ink printing failure prevention and treatment
Date: Jan 09 2024 From: Star Color
In the printing industry, paper water-based ink is widely used because of its environmental protection and safety characteristics.However, in the process of use, due to various reasons, some printing failures may be encountered, affecting production efficiency and product quality.This article will take you to a deeper understanding of these faults and provide practical prevention and treatment methods to help you improve production efficiency.
Paper water-based ink printing failure prevention
1.Choose the appropriate ink：Use ink with good compatibility and high stability with the substrate material.Avoid using ink that is out of date or of unstable quality.
2.Control ink viscosity：Adjust the viscosity of the ink according to the printing process requirements.Ensure that the viscosity is moderate to avoid false printing due to too low viscosity or printing difficulties due to too high viscosity.
3.Keep the press clean：Clean the press regularly, especially the ink rollers and printing surface.Avoid print quality problems caused by dust and impurities.
4.Pay attention to ambient temperature and humidity：Maintain a constant printing environment temperature and humidity.It is recommended that the temperature be controlled at 20-25 ° C and the humidity be maintained at 50-70%.Avoid uneven ink drying or print quality damage due to temperature and humidity fluctuations.
5.strengthen the training of staff：Regular training of printers to improve their operational skills and sensitivity to printing failures.Ensure that employees are able to detect and deal with small problems in a timely manner to prevent further failures.
Paper water-based ink printing fault treatment
1.color deviation：If there is a color deviation, you should first check whether the ink is out of date or mixed unevenly.If there is a problem, replace the ink immediately.If there is still a problem, you can adjust the ink amount or color sequence until you achieve satisfactory results.
2.Poor drying：If there is poor drying phenomenon, the exposure time of ink in the air can be properly extended to promote ink drying.At the same time, check whether the temperature and humidity of the printing environment are appropriate, and adjust accordingly if necessary.
3.Poor printing：The unclear printing may be related to factors such as ink viscosity and printing pressure.You can try to adjust the ink viscosity, increase the printing pressure or clean the printing surface to improve the printing clarity.
4.Paper fuzzing：Slight Paper fuzzing can be solved by increasing the printing pressure or adjusting the amount of ink.If the problem is more serious, it may be due to the quality of the ink or the poor condition of the press, you should check and replace the ink or repair the press.
5.other special problems：For other special problems, such as poor ink transfer, you can try to adjust the drying speed of the ink or change the printing process parameters to find the best solution.
case and case study：
1.A paper towel printing plant encountered color deviation when using paper water-based ink.After investigation and analysis, it was found that it was caused by the mixing of two different brands of ink.By adjusting to a single brand of ink and optimizing the color matching ratio, the problem was finally solved.
2.An enterprise encountered the problem of poor drying in the production process.After investigation, it was found that the workshop humidity was too low.By strengthening the workshop ventilation and increasing the dehumidification measures, the workshop environment was improved and the ink drying speed was increased.
3.The problem of unclear printing occurred in a printing enterprise.After inspection, it was found that the printing plate was caused by dust.By cleaning the printed surface and adjusting the printing parameters, the final result is a significant improvement in print quality.
When using paper water-based ink for printing, it is inevitable to encounter faults.The key is to prevent and deal with it in time.Through the in-depth analysis of common faults and case sharing, we hope to help you improve production efficiency, reduce costs, and provide strong support for improving product quality.In actual operation, it is also necessary to accumulate experience and continuously improve the process to adapt to the changing market demand and technological development.
