In the realm of printing, clarity, vibrancy, and sharpness are key attributes that define the quality of the printed output. Optical Brightener OB (Optical Brightening Agent OB) is a specialized chemical additive that plays a significant role in enhancing these qualities, particularly in achieving brighter whites and more vivid colors in printing inks. As a dedicated manufacturer and supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Optical Brightener OB to the printing ink industry.

The function of Optical Brightener OB in printing inks is similar to its role in plastics and textiles: it absorbs UV light and emits visible blue light. This phenomenon effectively cancels out yellow undertones in the ink formulation, leading to a brighter white appearance or creating a cleaner background for color printing. This enhancement is crucial for applications ranging from high-quality packaging and commercial printing to specialized graphic arts. For ink manufacturers, the ability to buy Optical Brightener OB from a consistent and reliable source is paramount for maintaining product quality and customer satisfaction.

When formulating printing inks, the particle size, dispersion characteristics, and purity of the optical brightener are critical. Our Optical Brightener OB is supplied as a fine powder with high purity (≥ 99.8%), ensuring excellent dispersibility within various ink bases, whether they are solvent-based, water-based, or UV-curable. Its good brightening effects and stability contribute to the overall performance and longevity of the printed image.
