For garment manufacturers seeking outstanding print quality with reduced operating costs, G&G image proudly introduces its premium 700-ml textile ink bags compatible with Brother GTX 422/423 series DTG printers. The G&G alternatives are built to deliver vibrant colors, stable performance and exceptional digital ink printing.
Direct-to-Garment (DTG) printing is a digital textile printing technology that applies water-based pigment inks directly onto finished garments such as T-shirts, hoodies, sweatshirts, tote bags and other fabrics.
Compared to traditional screen printing, DTG requires no screens or plates, allowing users to print full-color graphics, photographs and customized designs with minimal setup time. Powered by personalized, on-demand production and sustainable manufacturing, DTG printing has been one of the fastest-growing digital printing technologies. The global DTG printing market is projected to exceed USD 1.5 billion by 2030.
Featuring 1200 dpi high-resolution output, fast production speeds and excellent compatibility with a variety of fabrics, the Brother GTX Series printers have become one of the best-selling DTG printing devices across the imaging industry.
Leading in the mid-to-high-end apparel printing market, it was considered as the production workhorse for plenty of garment printing businesses. The Brother GTX 422/423 series DTG printers are widely used in:
Commercial customized apparel production
Fashion and lifestyle brands, creative merchandise
Caps, bags, shoes, uniforms and other fabric items

In real-world textile printing, businesses that purchased compatible DTG ink bags often struggle with issues such as ink clogging and nozzle dropouts, inconsistent ink flow, dull or inaccurate colors, low wash durability, poor compatibility and frequent maintenance.
These challenges not only affect print quality for garment decoration, also reduce production efficiency, increase material waste and operating costs, and ultimately impact profitability for those who distributed third-party textile printing products.
As the DTG printing industry expands, customers require dependable consumables that combine consistent quality, dependable performance and workflow efficiency.
G&G Image has developed and optimized its textile ink bags for use in Brother GTX 422/423 series printers. The new line combines textile inks made with high-purity pigments, pre-treated solution and cleaning techniques designed for reliable garment production.
The complete solution helps customers achieve exceptional print quality while maximizing productivity and reducing downtime. Whether producing one customized T-shirt or thousands of garments, G&G digital ink provides trusted performance every step of the way.
