2021 | Foundation Year — Breakthrough in DTF White Ink Dispersion Stability & Resolution of Core Industrial Pain Points
In the early stage of the domestic and international DTF printing industry, mainstream white ink products suffered from prevalent technical defects, including uneven pigment dispersion, severe sedimentation and delamination, poor suspension stability, and frequent printhead clogging. Conventional titanium dioxide-based white ink features high particle density and inferior suspension performance. Hard sediment accumulates rapidly at the bottom of ink tanks and pipelines after short-term static placement, resulting in skewed printing, missing nozzles, and discontinuous ink supply during high-speed operation. Furthermore, low-grade white ink commonly causes uneven base coverage, blurred color transition, and hot-press color bleeding, leading to high defective rates, frequent equipment shutdown and maintenance, and low mass production efficiency — key bottlenecks restricting the stable operation of industrial DTF production lines worldwide.
In 2021, targeting the above industrial technical bottlenecks, our R&D team completed independent formula development and structural optimization of white ink pigment systems. By adopting high-purity modified titanium dioxide particles and matching high-stability water-based dispersion systems, we thoroughly resolved the core technical problem of insufficient dispersion stability of traditional DTF white ink. We officially launched the first-generation high-coverage, low-sedimentation, smooth-printing DTF white ink series. The optimized formula effectively inhibits pigment agglomeration and precipitation, maintains consistent ink activity during long-term storage and continuous high-speed printing, and fundamentally eliminates common industrial issues such as printhead blockage, ink delamination, and transfer color bleeding. The product delivers stable ink output, uniform white base coverage, and accurate color restoration after hot stamping, significantly reducing equipment maintenance frequency and production defective rates for global printing enterprises.

2022 | Technical Upgrade — High Color Fastness & Superior Wash Resistance for DTG Water-Based Pigment Ink 

Traditional commercial DTG direct-to-garment water-based pigment inks have widespread inherent defects: insufficient color saturation, dull printing layers, weak fabric permeability, and low washing & friction fastness. Printed patterns produced with conventional inks are prone to fading, whitening, and peeling after repeated washing and long-term wear. In addition, most ordinary inks have strict limitations in fabric compatibility, failing to meet the printing and adhesion requirements of pure cotton, polyester-cotton blends, synthetic fibers and other composite materials. Such drawbacks make traditional products unable to satisfy the high-durability and personalized customization demands of modern garment mass production and high-end export orders.
In 2022, we achieved pivotal technological breakthroughs in high color fastness and ultra wash resistance of DTG water-based pigment ink. Through precise optimization of pigment particle grading, upgrading of water-based resin adhesion systems, and addition of high-efficiency anti-fading and anti-washing functional additives, the finished ink achieves a 30% increase in overall color saturation compared with traditional products, presenting more three-dimensional printing layers and vivid color restoration. The product’s washing fastness and dry & wet friction fastness stably reach Grade 4–5, fully complying with international garment printing durability standards. The upgraded ink features excellent universal material compatibility, supporting stable and high-precision direct spraying on pure cotton, blended fabrics, synthetic fibers and other mainstream textile materials. It effectively solves the long-standing industry pain points of easy washing fading, poor pattern adhesion, and single fabric applicability of traditional DTG inks, greatly improving the finished product yield and added value of garment direct-injection printing.

2023 | Industrial Iteration — Low-Powder & Powder-Free DTF Ink Technology Breakthrough & Green Compliance Upgrading
The conventional DTF printing process relies heavily on hot melt powder for lamination and transfer, bringing multiple industrial drawbacks: excessive powder scattering, severe workshop dust pollution, high auxiliary material costs, low hot stamping efficiency, and residual powder leading to poor fabric hand feel. Meanwhile, numerous low-end inks and supporting powder products on the market contain harmful volatile components and fail to meet international environmental compliance standards, making them ineligible for European and American export orders and standardized green production requirements. High powder consumption and low operational efficiency have long been major cost and efficiency bottlenecks restricting the scaled development of global DTF printing enterprises.
In 2023, aligned with the industry’s trends of high efficiency, cost reduction and green sustainable development, we achieved core technological breakthroughs in low-powder and powder-free DTF ink technology. Through innovative optimization of ink viscosity, surface tension and adhesive formula structure, our products realize low powder adhesion, uniform powder distribution and partial powder-free transfer molding. This innovation drastically reduces hot melt powder consumption, cuts raw material costs and workshop dust pollution, and comprehensively improves the operational efficiency of feeding, powder shaking and hot stamping processes. All products undergo rigorous third-party testing and fully comply with EU  and other international environmental compliance regulations. This technology effectively addresses the pain points of high production costs, low efficiency, substandard environmental performance and unstable finished product texture in traditional DTF processes, empowering printing enterprises to achieve compliant, efficient and low-consumption green production.

2024 | Performance Iteration — Low-Temperature Smooth Printing, Anti-Clogging & Fast-Drying Ink Formula Upgrade + Large-Scale Capacity Expansion
Most commercial printing inks have prominent adaptability defects in high-speed industrial mass production and desktop small-batch customized printing scenarios. Traditional ink formulas require high-temperature drying and shaping, which easily causes fabric shrinkage, pattern deformation and fiber damage. In addition, poor low-temperature fluidity, slow solvent volatilization speed and unstable dispersion under high-frequency printing conditions frequently trigger printhead clogging, intermittent ink breakage, uneven printing texture and stacked ink stains. These issues undermine printing fluency and finished product consistency, force frequent equipment shutdowns for cleaning and maintenance, and severely limit continuous high-speed production capacity. Moreover, most small and medium-sized ink suppliers suffer from insufficient production capacity, leading to long delivery cycles and unstable supply chains that cannot meet the growing bulk order demands of global printing manufacturers.
In 2024, we completed a comprehensive upgrade of core ink formulas, focusing on optimizing low-temperature fluidity, long-term anti-clogging performance and rapid drying technology. By adjusting ink molecular structure, optimizing solvent volatilization rates, and incorporating high-lubricity functional additives, the upgraded ink achieves stable molding under low-temperature working conditions, completely avoiding fabric deformation and pattern damage caused by high-temperature baking. The optimized anti-precipitation and anti-clogging formula maintains stable fluidity and suspension performance for a long time, compatible with both high-speed industrial printing equipment and commercial desktop printers with universal adaptability. The overall printing stability is improved by 50% compared with traditional formulas, thoroughly resolving industrial pain points such as frequent nozzle blockage, slow drying, unsmooth ink output and discontinuous production. Simultaneously, we completed production line intelligent upgrading and capacity expansion, achieving an annual textile ink output of 3,000 tons, which supports stable bulk supply, shortens global customer delivery cycles, and fully meets the large-scale standardized production demands of domestic and foreign printing enterprises.

2025–2026 | Strategic Layout — High-Standard Import Substitution & Ultra-Cost-Effective Global Compliant Solutions
The global high-end textile printing ink market has long been monopolized by international premium brands. Although imported ink products deliver stable basic performance, they have inherent disadvantages including excessively high procurement costs, long cross-border delivery cycles, single supporting services and low comprehensive cost performance, which continuously compress the profit margins of global small and medium-sized printing factories and cross-border export merchants. Most mid-to-low-end domestic alternative products have obvious gaps in color gamut reproducibility, printing smoothness, washing fastness and batch stability, failing to meet high-standard export specifications and industrial mass production quality requirements.
