Luminescent powder and luminescent ink have strong light absorption-light storage-luminescence ability due to their special crystal structure. When exposed to natural light and light, it absorbs and stores part of the light energy, and can slowly release it again in the form of visible light in the dark. Each light can last for 12 hours. The process of light absorption and light can be repeated countless times. Up to more than 20 years. Luminous powder is an ideal material for making luminous inks, luminous paints, luminous plastics, and luminous printing pastes.

Photoluminescent materials have a wide range of applications, from very small marks to marks on safety passages, or emergency exit marks. This material absorbs light and emits light in the dark. People use this feature to make many safety signs. Some products that are not safety signs, such as T-shirts, promotional materials, and small labels for children's toys, can be decorated and printed with photoluminescence. You can use pre-mixed inks, or you can purchase photoluminescent pigments and transparent primers to make your own. You can prepare water-based and solvent-based inks, including plastic melt inks.

The luminescent ink can automatically emit light for more than 12 hours in the dark after 5 minutes of illumination. Luminous ink is not only suitable for printing various patterns and characters with luminous effect, such as signs, toys, calligraphy and painting, glass painting, stickers, etc., but also because of its high transparency, good film-forming properties, and thin coating. It can be sprayed or screen-printed on all kinds of relief sculptures (Buddha statues, porcelain statues, plaster statues, Tang Sancai), polymer material paintings, light box paintings, lighting and other handicrafts, without affecting their original colors or lines. Everyone has increased its added value. The colors of luminous ink are transparent, red, blue, green, yellow, etc.

Photoluminescent materials contain non-radioactive and non-toxic zinc sulfide pigments. Depending on the content of zinc sulfide molecules and the conditions of receiving light, some materials can be used continuously for several years. In addition, it also contains light-reflecting materials, self-luminous materials and phosphorescent materials.

When using photoluminescent inks, in order to achieve good printing results, we must pay attention to the quality of the pigment and the cleanness and transparency of the primer, the quantity of the pigment, the color and surface characteristics of the printing material, and the thickness of the oil accumulation.

Do not heat the pigment too much during printing, as this will reduce the ability of the pigment to store and release light. Due to the sensitivity of the pigment, it must be dried at a low temperature after printing, or use a naturally drying ink during printing.
