What kinds of special requirements the applicable UV ink needs ?

May 10, 2018

UV ink is a specialized type of ink used for UV printing processes. It has unique properties that make it suitable for various applications. The specific requirements for UV ink depend on the intended use and the printing equipment being used. Here are some common special requirements applicable to UV ink:

  1. Fast Curing: UV ink needs to cure quickly when exposed to UV light. This rapid curing enables high-speed printing and efficient production processes.

  2. Adhesion: UV ink must adhere well to various substrates, including paper, plastic, metal, glass, and other materials commonly used in UV printing.

  3. Chemical Resistance: UV ink should be resistant to chemicals, solvents, and environmental factors to ensure the printed image remains intact and vibrant over time.

  4. Durability: UV ink is often used for outdoor applications, so it must be durable and resistant to fading, weathering, and UV radiation.

  5. Flexibility: For applications where the printed material may undergo bending or folding, UV ink should be flexible to prevent cracking or flaking.

  6. Low Volatile Organic Compounds (VOCs): Some applications may require UV ink with low VOC content, especially in industries with strict environmental regulations.

  7. Color Range: UV ink should be available in a wide range of colors to meet the diverse printing requirements of different industries.

  8. Food Safety Compliance: In applications involving food packaging or contact with food products, UV ink may need to meet specific safety regulations and requirements.

  9. Low Migration: UV ink used for packaging applications should have low migration properties to ensure that the ink does not transfer to the packaged product.

  10. Special Effects: Some applications, such as luxury packaging or specialty advertising, may require UV ink with special effects like metallic, glossy, or textured finishes.

  11. Opacity and Coverage: UV ink should provide good opacity and coverage to achieve vibrant colors and sharp images, even on dark or colored substrates.

  12. Eco-Friendly Options: Increasingly, there is a demand for eco-friendly UV ink formulations that have minimal impact on the environment.

Compared with ordinary ink, there are some requirements for printing equipment.

For example, at present, many enterprises install UV curing systems onto the ordinary offset machine to achieve UV printing.

But there are some problems in this way, such as the heavy corrosivity of uv ink can lead to the ordinary rubber roller and rubber cloth inflating, affecting the printing stability, the worse situation is that the rubber peels or cracks. Therefore, UV ink printing also has strict demand for rubber rollers and rubber cloth.

So the exclusive rubber roller and rubber cloth are necessary.
