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.

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.

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

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.

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%).
