Description

What Is NXG-15 Rubine Red Used For?

TW Graphics NXG-15 Rubine Red is formulated for applications requiring a cooler, magenta-based red tone that delivers strong visual impact and brand accuracy.

This UV rubine red ink is commonly used for:

  • Retail sale signage
  • Political yard signs
  • Real estate signs
  • POP displays
  • Brand color graphics
  • Promotional panels
  • Industrial and safety graphics
  • Vinyl decals and labels

NXG-15 delivers a bold, slightly blue-shifted red tone ideal for logos, promotional graphics, and brand-driven signage requiring a true rubine hue.

Designed for Sign Shops & Production Screen Printers:

Part of the TW Graphics NXG UV ink system, NXG-15 is engineered for consistent ink transfer, stable viscosity, and reliable curing performance. It runs smoothly on manual presses and high-speed automated in-line UV equipment.

This product is commonly used as a:

  • UV rubine red screen printing ink
  • UV magenta-leaning red ink
  • UV ink for Coroplast signage
  • UV red ink for plastics and vinyl
  • Production UV red screen ink

Where It Performs Best:

NXG-15 Rubine Red adheres to properly treated substrates including:

  • Treated polyethylene (PE)
  • High-density polyethylene (HDPE)
  • Polycarbonate (PC)
  • Polystyrene / Styrene
  • Pressure-sensitive vinyl
  • Static cling vinyl
  • Reinforced vinyl banners
  • Coated paper and board stocks
  • Corrugated plastic (Coroplast™)

For polyethylene substrates, surface tension should be 42–46 dynes/cm or higher. Always perform adhesion testing before full production runs.

How It Cures:

This is a true UV-curable ink. It does not air dry.

NXG-15 cures under focused medium-pressure mercury vapor UV lamps in the 250–360nm spectral range.

Typical UV energy requirements:

  • 150–300 mJ/cm² at 365nm (depending on ink film thickness)

Always verify cure using cross-hatch adhesion testing after full cooldown.

Pantone Equivalent:

  • Pantone Match – Pantone Rubine Red C (Closest Visual Equivalent)
  • Color Type – Standard rubine red
  • Intended Use – Brand colors, retail graphics, promotional signage

Why Screen Printers Choose NXG-15 Rubine Red:

  • True rubine tone – Magenta-leaning red for brand accuracy
  • Strong color saturation – Bold, clean coverage
  • Stable viscosity – Consistent performance during long runs
  • Broad substrate compatibility – Vinyl, plastics, Coroplast, coated board
  • Fully compatible with NXG UV system – Interprintable with NXG colors

NXG-15 Rubine Red is ideal for commercial sign shops that need consistent, vibrant red graphics with dependable UV curing performance.

Nazdar® Cross-Reference – Comparable UV Rubine Red Ink:

Looking for a Nazdar UV rubine red alternative?

TW Graphics NXG-15 Rubine Red functions similarly to rubine red inks used in Nazdar UV ink systems. Both are UV-curable inks designed for signage, plastics, and display applications.

As with any ink substitution, adhesion and cure testing should be completed prior to full production runs.

How to Use TW Graphics NXG UV Standard Colors

Step 1: Screen Preparation

  • Use a properly tensioned screen for optimal results.
  • Recommended mesh count230-355 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.
