How to improve the color vividness and brightness of flexo water-based fluorescent ink?
Release Time : 2025-02-24
Flexo water-based fluorescent ink plays an increasingly important role in the printing industry, and its color vividness and brightness are important indicators for measuring printing quality. Improving the color vividness and brightness of flexo water-based fluorescent ink can not only enhance the visual impact of the product, but also improve the overall printing effect.
First of all, optimizing the ink formula is the key. Adding an appropriate amount of fluorescent pigment to the ink can effectively improve the color vividness and brightness. Fluorescent pigments have a special luminous effect. After absorbing light energy, they can emit visible light with a longer wavelength than the absorbed light, so that the ink presents a brighter color. At the same time, the particle size and dispersibility of the pigment will also affect the color performance of the ink. Therefore, when designing the formula, it is necessary to select high-quality pigments and control the dispersion and particle size of the pigment to achieve the best color effect.
Secondly, adjusting the viscosity and fluidity of the ink is also crucial. The viscosity and fluidity of the ink will affect its transmission and spreading effect during the printing process. If the viscosity of the ink is too high, it will make it difficult to transfer the ink during the printing process, resulting in uneven color; if the viscosity is too low, it may cause uneven spreading of the ink during the printing process, affecting the vividness and brightness of the color. Therefore, before printing, it is necessary to adjust the viscosity and fluidity of the ink according to the performance of the printing machine and the characteristics of the printing material to ensure that the ink can be evenly transferred and spread during the printing process.
In addition, you can also consider adding an appropriate amount of brightener to the ink. Brightener is a special additive that can form a smooth film on the surface of the ink, improve the gloss and reflectivity of the ink, and make the color more vivid and bright. However, it should be noted that the amount of brightener added should be moderate, and excessive addition may affect the drying performance and adhesion of the ink.
Finally, the optimization of the printing process is also an important means to improve the color vividness and brightness of flexo water-based fluorescent ink. During the printing process, it is necessary to control parameters such as printing pressure, printing speed and ink supply to ensure that the ink can be evenly and stably transferred to the substrate.
In summary, improving the color vividness and brightness of flexo water-based fluorescent ink requires multiple aspects such as ink formulation, ink performance adjustment, additive use, and printing process.
