Screen Printing Ink For Plastic

Common screen printing ink for plastic include:

Solvent-based inks: Solvent-based inks have excellent adhesion and chemical resistance on plastic surfaces and are widely used in hard plastics such as PVC, ABS and polycarbonate.

UV-curable inks: These inks are cured by ultraviolet light and have the characteristics of fast drying and high gloss, making them suitable for plastic products that require fast production and high-quality printing.

Water-based inks: Although the use of water-based inks on plastics is relatively limited, they can still be applied to certain plastic surfaces through special formulations when environmental protection requirements are high.

Correct treatment for best printing results

 

Surface treatment:Pre-treating the plastic surface before printing, such as corona treatment or flame treatment, can help improve ink adhesion.

Proper curing: Make sure to use the appropriate drying or curing equipment and follow the ink manufacturer's recommendations to avoid poor printing results due to incomplete curing of the ink.

Proper storage: Screen printing ink for plastic should be stored in a cool, dry environment and avoid direct exposure to sunlight to prevent the ink from deteriorating or becoming ineffective.

Applications

 

Screen printing inks are widely used in plastic products. Due to their good adhesion and durability, they can achieve high-quality pattern, text and logo printing on various plastic materials.

 

Home Appliance Panels

Screen printing inks are widely used in panel printing of home appliances, such as washing machines, air conditioners and other equipment. The printed patterns and text have good wear and scratch resistance, and can maintain clarity and color for a long time.

 

Electronic Product Housings

Many electronic products, such as mobile phone cases, remote controls, keyboards, mice, etc., use screen printing inks to print brand logos, patterns and text on plastic housings. The ink can achieve fine pattern and text effects and can withstand friction and collisions in daily use.

 

Toys

In children's toys, screen printing inks are used to print colorful patterns and decorations to make the toys more attractive. The inks must meet safety and environmental standards to ensure that they are harmless to children.

 

Packaging Containers

Brand logos, product information and decorative patterns on plastic bottles, cans, boxes and other packaging containers are often achieved through screen printing. The high adhesion of the ink ensures that the pattern will not fall off due to friction, chemical contact or high temperature.

 

 

 

FAQ

1.Can I use the same screen printing ink on different types of plastic?
Not all plastics are suitable for the same ink. Different plastics absorb and adhere to ink differently, so it is recommended to select specific inks for the type of plastic to ensure the best results.

2.How can I avoid static electricity when screen printing on plastics?
Static electricity can cause uneven ink or attract dust, affecting the quality of the print. The effects of static electricity can be reduced by increasing humidity, using antistatic agents or static elimination devices.

3.How can I avoid color contamination when screen printing multiple colors on plastics?
To avoid color contamination, make sure that each color of ink is thoroughly dry before printing. You can also use a spacer layer or use a high mesh screen to reduce the risk of ink flow and color mixing.

4.How can I avoid inaccurate color overlay when screen printing on plastics?
To avoid inaccurate color overlay, make sure that each color is printed in the correct order and position. Use registration marks for precise positioning and ensure that each layer has sufficient drying time to prevent color mixing.

5.How can I avoid ink spreading when printing on plastics with water-based inks?
Spreading of water-based ink on plastic surfaces can be due to insufficient surface preparation of the plastic. The surface tension can be increased by pre-treating the plastic surface (such as corona treatment) or by selecting additives to improve the stability of the ink.
