Silicon dioxide is commonly used in inkjet color separation PET films to enhance their optical properties and improve the
printing process. Here are some key points about silicon dioxide in this context:
1. Optical properties: Silicon dioxide is a transparent and high-refractive-index material. When applied as a thin layer on
PET films, it helps to improve the optical clarity and transparency of the film, allowing for accurate color separation and
reproduction.
2. Ink absorption control: Silicon dioxide coatings can be engineered to control the absorption and spreading of ink on the
PET film surface. This helps to prevent ink bleeding or feathering, resulting in sharper and more vibrant color separation.
3. Anti-blocking properties: Silicon dioxide coatings also provide anti-blocking properties, reducing the adhesion between
PET film layers and preventing them from sticking together during storage or printing. This ensures easy handling and
smooth feeding of the film through inkjet printers.
4. Scratch resistance: The hardness and abrasion resistance of silicon dioxide coatings make the PET film more resistant to
scratches and damage during handling and printing processes. This helps to maintain the integrity of the color separation
layers and ensures consistent print quality.
5. UV protection: Silicon dioxide coatings can also provide UV protection to the PET film, preventing the color separation layers
from fading or degrading due to exposure to sunlight or other sources of UV radiation. This helps to prolong the lifespan and color
stability of the printed images.
Overall, the incorporation of silicon dioxide in inkjet color separation PET films improves their optical properties, ink absorption
control, anti-blocking properties, scratch resistance, and UV protection. These benefits contribute to better print quality, durability,
and longevity of the color-separated images.
