China Manufacturer of Silk Screen Ink

Screen printing on glass bottles is a common surface decoration process widely used in packaging containers such as cosmetic bottles, beverage bottles, and medicine bottles. 

The process begins with cleaning the glass bottles to ensure the surface is free of dust and oil.

Then, a screen is created according to the design, and specialized glass ink is prepared.

During printing, it is crucial to control the ink viscosity, squeegee pressure, and the distance between the screen and the bottle.

After printing, baking and curing are necessary to ensure a strong bond between the ink and the glass surface. This process offers advantages such as high image precision, rich colors, and excellent wear resistance.

Compared to labeling, screen-printed designs adhere directly to the bottle, eliminating issues like peeling or flaking. It also allows for various special effects, such as frosted, glossy, and pearlescent finishes, to meet diverse aesthetic preferences.

In practical applications, it is essential that the ink selection meets food safety standards, especially when used for food packaging.

Furthermore, different shaped glass bottles require specialized clamps for secure fixing to ensure accurate printing positioning.

Strict control of ambient temperature and humidity is also crucial during production to avoid affecting ink flow and curing performance. With advancements in technology, multi-color printing and gradient effects are now possible, offering greater possibilities for product design.

This traditional technique continues to play a vital role in modern manufacturing, constantly adding value to various products through continuous innovation.
