How to Use TW Graphics NXG UV Standard Colors

Step 1: Screen Preparation

• Use a properly tensioned screen for optimal results.
• Recommended mesh count: 230-355 tpi (90-140 tpcm), depending on image detail.
• Coat the screen with a UV-compatible emulsion, ensuring full stencil adhesion.

Step 2: Ink Application

• Stir the ink thoroughly before use.
• Print using a 70-80 durometer squeegee with a sharp edge for crisp details.
• Use a medium squeegee pressure for optimal ink deposition.

Step 3: Curing Process

• Cure under UV light exposure at 150-300 mJ/cm² for full adhesion.
• Ensure proper exposure time in the dryer to avoid under-curing.
• Avoid excessive UV exposure, which can overcure and affect adhesion properties.

Step 4: Testing & Post-Curing Considerations

• Always perform an adhesion test on a sample print to verify cure levels.
• Allow the print to cool before stacking or packaging.
• NXG inks are designed for optimal adhesion, but post-treatment options (such as flame or corona treatment) may be required for certain non-porous substrates.

Recommended Printing Substrates:

✅ Plastics & Synthetics: Treated Polyethylene, HDPE, Polycarbonate, Polystyrene (Styrene), Static Cling Vinyl
✅ Rigid Boards & Papers: Coated Board Stocks, Cardstock, Pressure-Sensitive Vinyl
✅ Banners & Signage: Reinforced Vinyl Banners, Coroplast™, Transit & Point-of-Purchase Displays

⚠ Important Notes:

• This ink requires UV curing and will not air-dry.
• Do not mix with solvent-based inks or non-UV-compatible additives.
• Store in a cool, dry environment away from direct sunlight.

TW Graphics NXG UV Standard Colors deliver fast-curing, high-adhesion, and long-lasting performance, making them the perfect choice for screen printers working with plastic, vinyl, banners, and signage applications.
