Screenprinting Inks

Classification

Depending on the different uses and materials, screen printing inks can be divided into the following types:

 

Solvent-based inks: commonly used for printing non-absorbent materials such as plastics and metals. The ink is dried by solvent evaporation and is suitable for occasions that require high-strength adhesion.

 

Water-based inks: With water as the main solvent, it is more environmentally friendly and is commonly used for printing absorbent materials such as paper and textiles. The drying method is usually natural air drying or hot air drying.

 

UV curing inks: The chemical components in the ink react through ultraviolet irradiation, thereby curing quickly. Suitable for high-speed printing, commonly used for printed products with high gloss and high wear resistance requirements.

 

Thermosetting inks: The binder in the ink needs to be chemically changed by heating to cure the ink. It is usually used for printed products that need to be resistant to high temperatures, such as glass or ceramics.

 

Special inks: Such as fluorescent inks, metallic inks, conductive inks, etc., suitable for printing with specific functional or decorative requirements.

Application areas

Screenprinting inks have a wide range of applications

Textile printing

such as T-shirts, bags, etc.

Electronic products

such as circuit boards, touch screen printing.

Packaging printing

such as labels, plastic packaging bags.

Crafts and artworks

such as posters, art prints.

 

Characteristics of screenprinting inks

Strong applicability : can be printed on a variety of materials.

Bright colors : due to the thick ink layer, the color expression is strong.

Good durability : under proper treatment, the printed product has strong wear resistance and weather resistance.

Simple process : the equipment and process are relatively simple, suitable for small and medium batch production.

1.What is the difference between screen printing ink and regular ink?
Screen printing ink is designed for screen printing process and has higher viscosity and thicker printing layer to adapt to printing through screen. Regular ink is usually used for other printing methods, such as offset printing and gravure printing, and has different fluidity and drying characteristics.

2.What is UV curing ink?
UV curing ink is a type of ink that cures the ink quickly through ultraviolet light. It is suitable for printed materials that require fast drying and high wear resistance, such as plastic, glass and metal surfaces.

3.How to choose the right screen printing ink?
When choosing ink, factors such as substrate, fineness of printed pattern, drying method, and use environment should be considered. Different materials and needs correspond to different types of inks, such as solvent-based, water-based, UV curing, etc.

4.Can screen printing ink be used for a variety of substrates?
Yes. Screen printing ink is suitable for a variety of substrates, such as paper, cloth, plastic, metal, glass, etc. But different materials require different types of inks to ensure adhesion and durability.

5.What is water-based screen printing ink?
Water-based ink uses water as the main solvent, which is more environmentally friendly and suitable for absorbent materials such as paper and textiles. The drying method is usually natural air drying or hot air drying.
