The high overheads associated with traditional digital pigment printing often stem from the labor-intensive fabric pre-treatment (sizing and drying) process. INKBANK’s latest innovation—a pre-treatment-free pigment ink, optimized specifically for Ricoh G6 printheads, disrupts this technical paradigm.

. Its core breakthrough lies in the ability to print directly onto raw, untreated fabrics (such as canvas and cotton) without the need of any pre-treatment coating, achieving exceptional deep colors and ultra-high optical density (high OD values). Furthermore, its rub fastness doesn’t just hold steady—itactually outperforms traditional processes, offering modern printing facilities a high-efficiency, cost-saving roadmap.

1. The Pre-treatment "Profit Trap": Invisible Barrier to Growth

In the current digital pigment printing workflow, manufacturers must pre-coat and dry fabrics with chemical primers to prevent "bleeding" (dull, washed-out prints) and to enhance vibrancy. However, this necessity creates three critical pain points:

• Batch Color Inconsistency: Even minor fluctuations in the uniformity of pre-treatment sizing can lead to varying color depths across the same batch, resulting in high reject rates.

• Escalating Operational Costs: Beyond the initial capital investment for pre-treatment equipment, the ongoing natural gas/electricity consumption (for drying energy) and additional labor costs severely squeeze profit margins.

• Compromised Fabric Hand-Feel: The accumulation of chemical additive layers often destroys the natural softness and breathability of premium cotton or canvas fabrics.

2. Core Breakthrough: Unleashing Deep Colors (High OD Values) on "Untreated Fabrics"

A prevailing industry misconception suggests: “Without pre-conditioning, pigment printed on untreated fabric will inevitably appear muted, greyish, and superficial.”

The INKBANK R&D team has debunked this myth with empirical data. Through proprietary high-concentration pigment dispersion and advanced resin integration technology, this pre-treatment-free ink delivers high-impact color performance even on entirely untouched raw fabrics:

• Superior Black Density (Deep, Saturated Black): Comparative lab metrics reveal that while conventional pigment ink on treated fabric yields a Black (K) OD value of 1.140, INKBANK’s formulation on raw fabric reaches 1.148. This demonstrates that, even without a primer coat, blacks remain exceptionally pure and solid, with zero greyish undertones.

• Vibrant Process and Spot Color Reproduction: From standard Cyan (C), Magenta (M), and Yellow (Y) to challenging spot colors like Orange (OR), Red (R), Blue (B), and Green (G), the tristimulus coordinates (Lab) and OD levels consistently align with benchmarks set by* traditional processes. The ink inherently provides high-performance penetration and chromaticity, negating the requirement for chemical primers to anchor the color.

3. Beyond Expectations: Superior Color Fastness and Jetting Stability

The elimination of pre-treatment naturally raises the question: is print quality compromised? On the contrary, the results are even more compelling and provide total operational confidence.

1. Color Fastness: Outperforming Industry Benchmarks

   Under standard curing conditions (150°C for 3 minutes in a tunnel oven, without post-wash finishing), the dry and wet crocking resistance of this pre-treatment-free ink on raw fabric is exceptional. Notably, dry rub fastness for core colors generally improves by one full grade. Even more impressively, the notoriously challenging wet rub fastness sees a significant improvement of 1–2 grades compared to traditional pre-coated processes.

2. Engineered for the Ricoh G6

Seamless Performance and Longevity High-performance ink must be harmonized with the hardware. This formulation is engineered to support 90 meters of continuous, high-speed printing without jetting interruptions, even in demanding high-temperature workshop environments. It maintains a 30-minute standby period without nozzle dropouts. During daily operation, only 1–2 routine cleaning cycles are required to achieve peak performance, drastically lowering maintenance overhead and extending the lifespan of expensive industrial printheads.
