Description

What Is NXG-44 Halftone Extender Base Used For?

TW Graphics NXG-44 Halftone Extender Base is a professional-grade UV process base used to modify and control color strength in halftone printing applications. It allows printers to adjust ink density without affecting cure performance when used within recommended ratios.

If you need to:

Reduce color strength in process inks
Fine-tune dot gain and tonal values
Improve highlight detail
Control ink density in four-color process printing
Increase ink mileage while maintaining consistency

NXG-44 Halftone Extender Base is built for those applications.

It is commonly used in advanced CMYK workflows where color balance, tonal accuracy, and controlled transparency are critical.

Designed for Sign Shops & Production Screen Printers:

Part of the TW Graphics NXG Advanced Color Gamut Halftone Colors™ system, NXG-44 is engineered specifically for compatibility with NXG halftone process inks. It integrates into the ink system without disrupting cure speed or adhesion when used properly.

This product is commonly used as a:

UV halftone extender base
UV process ink reducer base
UV screen printing ink modifier
UV four color process base
UV halftone mixing base

It provides controlled reduction of pigment strength while maintaining proper ink flow and printability.

How to Use NXG-44 Halftone Extender Base:

Mix into NXG halftone inks to reduce color density
Adjust in small increments and test before full production
Maintain proper mesh count for accurate halftone reproduction
Verify cure and adhesion after adjustment
Stir thoroughly before use

Always perform press testing and color calibration before production runs.

Where It Performs Best:

NXG-44 Halftone Extender Base is compatible with:

NXG-45 Halftone Yellow H.D.
NXG-46 Halftone Magenta H.D.
NXG-47 Halftone Cyan H.D.
NXG-48 Halftone Black H.D.

It is suitable for printing 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.

How It Cures:

NXG-44 is a true UV-curable base. It does not air dry.

It cures under focused medium-pressure mercury vapor UV lamps in the 250–360nm spectral range. Typical UV energy requirements range from 150–300 mJ/cm² at 365nm, depending on total ink film thickness.

Proper UV settings and testing are required when modifying process inks.

Pantone Equivalent:

Pantone Match – N/A (Extender Base)
Color Type – Process modifier / transparent base
Note – This product modifies pigment strength and transparency and does not contain color pigment on its own.

Why Screen Printers Use NXG-44 Halftone Extender Base:

Precise density control – Fine-tune CMYK color balance
Improved highlight detail – Enhance halftone transitions
Maintains cure performance – Compatible with NXG UV chemistry
Production flexibility – Adjust tonal strength as needed
Designed for process printing – Optimized for advanced color gamut systems

NXG-44 Halftone Extender Base is essential for printers running high-resolution four-color process jobs where color accuracy and tonal control matter.

Nazdar® Cross-Reference – Comparable UV Process Extender:

Looking for a Nazdar UV process extender alternative?

TW Graphics NXG-44 Halftone Extender Base is comparable in function to UV process extender bases used in Nazdar four-color screen printing systems. Both are designed to reduce pigment strength and control tonal values in CMYK printing applications.

As with any ink system modification, adhesion, cure energy, and color calibration testing should be completed prior to full production runs.

TW Graphics NXG UV Standard Colors – Technical Specs & Usage Guide

Technical Specifications:

Ink Type: UV Curable Screen Printing Ink
Viscosity: Optimized for multi-color in-line presses
Curing Method: UV light exposure
Curing Energy Requirement: 150-300 mJ/cm²
Adhesion: Bonds to treated plastics, vinyl, and various rigid substrates
Durability: Up to 2 years light-fastness with automotive-grade pigments
Resistance: Water-resistant and highly durable for indoor & outdoor applications

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.
