Specifications and Maintenance of 2-Color Non-Woven Bag Screen Printing Machine

A 2-color non-woven bag screen printing machine is a vital tool in the production of eco-friendly tote bags, promotional carriers, and reusable shopping bags. These machines offer efficient, high-volume printing with excellent color registration and durability. Understanding the technical specifications ensures optimal print quality, while a structured maintenance routine extends equipment life and reduces downtime.

Key Technical Specifications

Screen Frame Material

Aluminum is the most widely used material for screen frames in textile and non-woven fabric printing due to its ideal balance of strength, rigidity, and lightweight properties. Aluminum frames maintain consistent mesh tension over time, which is critical for sharp, repeatable prints. They are also corrosion-resistant and easy to handle, making them suitable for frequent use in industrial environments.

Properly tensioned aluminum screens reduce ink bleeding and improve image clarity, especially important when printing fine details or halftones on non-woven polypropylene materials.

Screen Mesh Count

The mesh count—measured in threads per inch (TPI)—determines ink deposition and detail resolution. For non-woven bag printing, a mesh count between 110 and 160 TPI is typically ideal.

Lower mesh counts (110–120 TPI) are best suited for plastisol inks, which are thicker and require more open area for proper ink transfer. Higher mesh counts (140–160 TPI) work well with water-based inks, allowing finer detail and smoother gradients while preventing ink from seeping into the porous non-woven fabric.

Flash Dryer System

A flash dryer is essential in multi-color screen printing operations. It applies controlled bursts of heat (typically 250°F–320°F) to partially cure or "gel" the first ink layer before the second color is applied.

In a 2-color machine, this prevents color mixing, smudging, and bleeding—common issues when wet ink layers come into contact. An effective flash curing system ensures crisp color separation and enhances production speed by eliminating long drying waits between prints.

Ink Compatibility

The choice of ink significantly affects print durability, color vibrancy, and environmental impact. For non-woven polypropylene bags, plastisol ink is preferred due to its opacity, adhesion, and resistance to cracking. It performs exceptionally well on synthetic fabrics and offers vibrant colors ideal for branding and logos.

For eco-conscious brands, water-based inks are a sustainable alternative. They are biodegradable and produce softer hand feel, though they may require pretreatment or longer drying times. Selecting the right ink depends on fabric composition, wash durability requirements, and sustainability goals.

Print Area Size

The standard print area for non-woven bag screen printing machines is approximately 12" x 16" (30cm x 40cm), which accommodates most tote bag designs, including center chest prints and side panels.

Some 2-color machines offer adjustable platens or interchangeable print heads to support smaller or larger print zones. Ensuring the machine’s print area matches your bag dimensions avoids design truncation and maximizes ink coverage efficiency.

Color Registration System

Precise color registration is crucial in 2-color printing to ensure perfect alignment between overlapping or adjacent colors. Most machines feature micro-adjustable print heads with registration pins or digital alignment guides.

High-quality registration systems allow operators to fine-tune X, Y, and angular positioning, minimizing misprints and reducing material waste. Consistent registration improves overall print quality and brand professionalism.
