To avoid fading of BOPP color synthetic paper during printing, the following measures can be taken:
1、 Choose high-quality paper and ink
Paper quality: Choose high-quality BOPP color synthetic paper with uniform and bright colors, no obvious color difference or spots. This type of paper has better light resistance, heat resistance, and chemical resistance, which helps reduce fading.
Ink quality: Use high-quality ink, especially those designed specifically for BOPP color synthetic paper. These inks usually have better adhesion and color stability, which can reduce fading.
2、 Optimize print settings
Printing temperature: Adjust the printing temperature of the printer based on the characteristics of the paper and ink. Excessive temperature may cause ink to dry too quickly, thereby affecting color stability.
Printing speed: Appropriate printing speed can ensure that ink fully penetrates into the paper, forming a stable color layer. Excessive printing speed may result in incomplete ink drying or penetration, increasing the risk of fading.
Printing density: Reasonably set the printing density to ensure that the printed image or text is full in color and not easily faded. Excessive ink may result in colors that are too bright but unstable, while excessively light ink may fade easily due to insufficient color.
3、 Control storage and usage environment
Storage environment: Store BOPP colored synthetic paper in a dry, ventilated, and dust-free environment, avoiding direct sunlight and high temperature and humidity conditions. This storage environment helps reduce paper fading caused by moisture, aging, and other factors.
Usage environment: During the printing process, ensure that the printer and paper are in a suitable usage environment, such as temperature, humidity, etc. Avoid using paper in extreme environments to reduce fading.
4、 Pay attention to operating standards
Avoid scratching: During use, avoid scratching or damaging the surface of the paper to avoid affecting the printing effect and color stability.
Regularly clean the printer: Regularly clean the print head and nozzle of the printer to ensure smooth ink ejection and even distribution, thereby reducing fading.
5、 Consider paper batch and shelf life
Pay attention to paper batches: There may be slight differences between different batches of paper, including color stability and light resistance. When using, attention should be paid to distinguishing paper batches to avoid the problem of fading caused by mixing.
Pay attention to the shelf life of paper: Paper stored for a long time may experience a decrease in color stability due to aging. Therefore, before use, attention should be paid to the shelf life of the paper and try to use it within the shelf life as much as possible.
In summary, by selecting high-quality paper and ink, optimizing printing settings, controlling storage and usage environments, paying attention to operating standards, and considering paper batches and shelf life, it is possible to effectively avoid fading of BOPP color synthetic paper during the printing process.
