SOLVENT BASED INK HOW IT WORKS

The 3 steps to follow when using

Ink Formulation and Printing

Stir thoroughly: After opening the can, stir the contents thoroughly. Two-component inks must be mixed in the specified ratio.

Curing conditions

Low-temperature curing: Cure at 100–130°C for 20–30 minutes, or cure at 180°C or above for 10–15 minutes (depending on ink type).

Storage and Security

Sealed Storage: Unused ink must be sealed and stored at 0-10°C. Avoid high temperatures and direct sunlight.

Characteristics

With focus on turning ideas into actions

EVA flip flop ink

EVA slipper screen printing ink is specially formulated for the characteristics of EVA materials. It combines excellent adhesion, flexibility, and abrasion resistance, ensuring bright and long-lasting prints on EVA slipper surfaces.

Shoe upper embossing ink

This ink specially designed for shoe uppers that require heat pressing. Patterns printed on the uppers can withstand high temperature and high-pressure treatment while maintaining vibrant colors, strong adhesion, and clear designs, making it ideal for sports shoes, casual shoes, and customized footwear.

Waterproof Nylon Ink

This ink is specially developed for nylon waterproof fabrics. It offers excellent adhesion and durability, firmly bonding with the fabric surface. The printed patterns remain vibrant and bright, resistant to fading, washing, and abrasion, ensuring long-lasting clarity.

Solvent based ink

HOW IT WORKS

Key considerations for screen
printing Solvent based ink:

1. Mesh count: Recommended 80-120 mesh. Excessively high mesh counts may prevent silicone from passing through, while excessively low counts may cause uneven flow.
2. Photoresist thickness: Requires 0.1-0.5mm to enhance three-dimensional effects. Adjust based on sample thickness.

Screen Selection and Plate Making

1.Two-component silicone: Requires mixing of A/B components, baking at 120-160°C, offers strong adhesion but requires high-temperature resistant materials.
2.One-component silicone: Air-dries naturally (6-10 minutes), suitable for fabrics or plastics that cannot withstand high temperatures.

Ink Types and Curing

1. Ink Layer Thickness: Conductive ink must be >30μm, with resistance <200Ω (4mm spacing)
2. Squeegee Hardness: Approx. 55° Shore A, speed 12-24 cm/s, to prevent deformation of curved key bodies
3. Design Specifications: Character spacing should not be too close; background area should be 0.1-0.2mm smaller than surface color to prevent adhesion

Printing Process Control

1. Color Variation: A 0.1μm variation in ink layer thickness can cause noticeable color differences, requiring strict control of ink-water balance.
2. Screen Clogging: Excessively rapid solvent evaporation may clog mesh openings; add defoaming agents (e.g., SSYK defoamer at 0.5-1.0%).

Frequently Asked Questions

1. VOC Restrictions: Must comply with standards such as EU Directive 2004/42/EC to control volatile organic compound emissions.
2. Food Contact Safety: For food packaging applications, must meet migration limits and heavy metal thresholds specified in GB 4806.14-2023.
