Water Based Screen Printing Premium Ink

Key Features and Advantages

A. Upgraded Raw Materials: Polyurethane System

Premium inks typically use water-based polyurethane or polyurethane-acrylic copolymers as binders.

Revolutionary Feel: Ordinary acrylic resins tend to be hard after drying, while polyurethane molecular chains are soft and have shape memory. The dried ink layer feels like an integral part of the fabric, making it especially suitable for high-end fabrics such as Lycra, Modal, and mercerized cotton.

Physical Properties: Possesses extremely high tensile strength and resilience. Even when printed on highly elastic sportswear, repeated stretching does not easily cause cracks or show-through.

B. Optimized Process: Excellent Printability

Non-clogging: Premium formulations typically contain finer humectants and rheology modifiers. During long printing sessions, the ink dries on the screen 30%-50% slower than ordinary water-based inks, significantly reducing downtime for screen cleaning due to clogging.

Edge Sharpness: Thixotropic (thinns when stirred, thickens when still). After passing through the screen, it sets quickly without bleeding, making it suitable for printing high-resolution dots of 200 mesh or higher, or extremely fine lines below 0.2mm, achieving photo-quality gradient effects.

C. Fastness and Post-treatment
Wash Fastness: No additional hardener is needed; standard high-temperature curing (150°C-160°C, 2-3 minutes) is sufficient to achieve AATCC 4.5-5 wash fastness.

Resistance to Special Processes: It can withstand garment finishing processes such as enzyme washing, stone washing, and sand washing. Ordinary water-based inks are prone to peeling after enzyme washing, while Premium inks, with their special cross-linking design, retain vibrant colors after washing and have a softer, more natural feel.

 

👕Suitable Fabrics:

High-end knitwear: Mercerized cotton, long-staple cotton, organic cotton, Modal, Tencel.

High-elasticity fabrics: Sports and yoga wear, swimwear (requires a special curing agent), Lycra cotton.

 

FAQ:

What are the specific differences in cost and performance between your advanced water-based inks and ordinary acrylic water-based inks on the market? What benefits does the extra cost actually bring?

Although the unit price of your advanced ink series is typically 20%–30% higher than that of ordinary acrylic water-based inks, the overall production cost is actually lower:

Improved printing efficiency: Ordinary water-based inks usually require 2–3 passes → intermediate drying → reprinting when printing light colors on dark fabrics. Our high-opacity series uses a high-solids polyurethane system, achieving the same opacity in a single pass, reducing printing time by approximately 40%–50%, and significantly lowering labor and energy costs.

Improved yield: Ordinary water-based inks are prone to problems such as screen clogging, bleeding, and incomplete drying leading to returns after washing. Advanced inks, through optimized rheology and moisture retention, reduce the probability of screen clogging by more than 70%, and have a wider curing window (maintaining fastness even with a temperature deviation of ±10°C), effectively reducing defective product losses.

Value-added enhancement: Using high-grade inks allows for orders from brands with extremely high requirements for fastness and hand feel, with order prices potentially 30%–50% higher than ordinary printing. For printing factories, this investment represents an upgrade in production tools, rather than simply a cost of consumables.
