Description

What Is NXG-31 Overprint Clear Used For?

TW Graphics NXG-31 Overprint Clear is a professional UV clear coat applied over finished prints to increase gloss, protect ink layers, and extend graphic durability.

This high-gloss overprint clear is commonly used for:

  • Retail signage
  • POP displays
  • Political yard signs
  • Real estate signs
  • Menu boards
  • Promotional panels
  • Indoor and outdoor graphics
  • Decals and display materials

NXG-31 enhances color vibrancy by adding gloss while protecting the underlying print from handling, abrasion, and environmental exposure.

Designed for Sign Shops & Production Screen Printers:

Part of the TW Graphics NXG UV ink system, NXG-31 is engineered for smooth laydown, stable viscosity, and reliable UV curing performance. It performs consistently on manual presses and automated in-line UV production equipment.

This product is commonly used as a:

  • UV overprint clear ink
  • UV gloss clear coat
  • UV protective topcoat for screen printing
  • UV finishing layer for signage
  • UV high-gloss screen printing clear

Where It Performs Best:

NXG-31 Overprint Clear adheres well to properly cured NXG colors and performs on:

  • 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 overprint clear. It does not air dry.

NXG-31 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 film thickness)

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

Pantone Equivalent:

  • Pantone Equivalent – N/A (Clear)
  • Color Type – High-gloss overprint clear
  • Intended Use – Protective and gloss-enhancing topcoat

Why Screen Printers Choose NXG-31 Overprint Clear:

  • High-gloss finish – Enhances color depth and vibrancy
  • Protective topcoat – Improves abrasion and chemical resistance
  • Smooth application – Consistent film build
  • Broad substrate compatibility – Vinyl, plastics, Coroplast, coated board
  • Fully compatible with NXG UV system – Designed for use over NXG colors

NXG-31 is ideal for commercial sign shops producing graphics that require added surface protection and a premium high-gloss appearance.

Nazdar® Cross-Reference – Comparable UV Overprint Clear:

Looking for a Nazdar UV clear alternative?

TW Graphics NXG-31 Overprint Clear functions similarly to UV overprint clears used in Nazdar UV ink systems. Both are UV-curable topcoats designed to protect graphics and enhance gloss levels.

As with any overprint clear, proper cure verification and adhesion testing should be completed prior to full production runs.
