UV Coding Ink for TIJ/PIJ Printers – Fast Dry, High Adhesion
What Is UV Inkjet Coding Ink?
UV inkjet ink is an industrial marking ink that is cured by ultraviolet (UV) light. It is commonly used in UV inkjet systems (such as TIJ, PIJ, UV-CIJ, etc.). It does not require penetrating materials and can be instantly cured into a film by irradiating ultraviolet rays. It is widely used in marking printing on non-absorbent materials such as plastics, metals, and glass.

Advantages of UV Inkjet Ink
Instant drying upon printing, no curing time required — ideal for high-speed production lines.
Adheres to non-absorbent materials, solving adhesion issues common with traditional inks.
Supports high-resolution printing of 1D/2D barcodes, small characters, and dynamic graphics.
Scratch-resistant and highly chemical-resistant, ensuring long-term data integrity.
Low odor, solvent-free, and environmentally friendly — suitable for enclosed spaces or eco-compliant enterprises.
Precautions
1. Use with UV Light Source
Must be used with a UV LED lamp to ensure proper ink curing. Different inks require matching UV wavelengths (commonly 365nm or 395nm).
2. Control Printing Environment
Maintain an optimal temperature of 20–30°C. Avoid high humidity, which can cause dust to stick to the ink surface.
Aging UV lamps may lead to insufficient curing—regularly check UV intensity.
3. Prevent Premature Curing
Store ink away from light to prevent premature curing. During operation, avoid direct UV exposure to the ink system or nozzle area.
Use dark-colored, light-blocking ink cartridges or tubing to prevent skinning.
4. Ink Compatibility and Maintenance
Thoroughly flush the ink system before switching to a different ink brand.
UV coding inks have specific viscosity and surface tension properties that impact printheads, so use formulations compatible with the printhead model.
