UV INVISIBLE INK HOW IT WORKS<\/span><\/p><\/h1><\/div>

The 3 steps to follow when using<\/span><\/p><\/h1><\/div><\/div><\/div><\/div>

<\/i><\/div>

Ink Formulation and Printing<\/h2><\/a><\/div>
<\/div>
\n

Stir thoroughly: After opening the can, stir the contents thoroughly. Two-component inks must be mixed in the specified ratio.<\/span><\/p>\n<\/div>

Curing conditions<\/h2><\/a><\/div>
<\/div>
\n

Low-temperature curing: Cure at 100\u2013130\u00b0C for 20\u201330 minutes, or cure at 180\u00b0C or above for 10\u201315 minutes (depending on ink type).<\/span><\/p>\n<\/div>

Storage and Security<\/h2><\/a><\/div>
<\/div>
\n

Sealed Storage: Unused ink must be sealed and stored at 0-10\u00b0C. Avoid high temperatures and direct sunlight.<\/span><\/p>\n<\/div>

<\/div><\/div>

Invisible Stitching Marking<\/strong><\/p>\n<\/div>

Used in line drawing and screen printing for shoe materials.Invisible under normal light, visible only under UV light.Ensures accurate stitching without affecting appearance or design.<\/span><\/p>\n<\/div>

Bright UV Visibility & Fast Drying<\/strong><\/p>\n<\/div>

Transparent in normal light with strong UV fluorescence.Easy to identify and verify under UV light.Fast drying, suitable for high-speed footwear production.<\/span><\/p>\n<\/div>

Strong Adhesion & Safe Use<\/strong><\/p>\n<\/div>

Excellent adhesion on synthetic leather, textile, and coated uppers.Durable and reliable during stitching and handling.Non-toxic and safe for footwear manufacturing.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

Screen Selection and Plate Making<\/h2><\/div>

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.
\n2. Photoresist thickness: Requires 0.1-0.5mm to enhance three-dimensional effects. Adjust based on sample thickness.<\/p>\n<\/div><\/div><\/div>

Ink Types and Curing<\/h2><\/div>

1.Two-component silicone: Requires mixing of A\/B components, baking at 120-160\u00b0C, offers strong adhesion but requires high-temperature resistant materials.
\n2.One-component silicone: Air-dries naturally (6-10 minutes), suitable for fabrics or plastics that cannot withstand high temperatures.<\/p>\n<\/div><\/div><\/div>

<\/i><\/div><\/div>
<\/div><\/div>
<\/i><\/div><\/div><\/div>

Printing Process Control<\/h2><\/div>

1. Ink Layer Thickness: Conductive ink must be >30\u03bcm, with resistance <200\u03a9 (4mm spacing)
\n2. Squeegee Hardness: Approx. 55\u00b0 Shore A, speed 12-24 cm\/s, to prevent deformation of curved key bodies
\n3. Design Specifications: Character spacing should not be too close; background area should be 0.1-0.2mm smaller than surface color to prevent adhesion<\/p>\n<\/div><\/div><\/div>

<\/div><\/div>

Environment and Safety<\/h2><\/div>

1. VOC Restrictions: Must comply with standards such as EU Directive 2004\/42\/EC to control volatile organic compound emissions.
\n2. Food Contact Safety: For food packaging applications, must meet migration limits and heavy metal thresholds specified in GB 4806.14-2023.<\/p>\n<\/div><\/div><\/div>

Frequently Asked Questions<\/h2><\/div>

1. Color Variation: A 0.1\u03bcm variation in ink layer thickness can cause noticeable color differences, requiring strict control of ink-water balance.
\n2. Screen Clogging: Excessively rapid solvent evaporation may clog mesh openings; add defoaming agents (e.g., SSYK defoamer at 0.5-1.0%).<\/p>\n<\/div><\/div><\/div><\/div><\/div>
