Rotary Printing
Rotary printing is a high-speed printing technique used to apply intricate patterns and designs on fabrics. It's typically used for mass production of printed fabrics, especially for large quantities of patterned textiles.
How It Works:
- In rotary printing, fabric is passed through a series of engraved cylinders (rotary screens), each carrying a different part of the design.
- The fabric moves through a print paste (often containing dyes or pigments), and as the fabric passes under each cylinder, the design is transferred onto the textile.
- The cylinders rotate continuously, allowing for a rapid application of complex designs.
Advantages:
- High-speed, making it ideal for large-volume orders.
- Suitable for multi-color patterns, including intricate and continuous designs.
- Cost-effective for large batches.
Flatbed Printing
Flatbed printing is a more traditional method of printing used to apply patterns on fabrics, which can range from simple to very detailed designs. It is typically used for small to medium-sized print runs.
How It Works:
- In flatbed printing, a flat screen (or plate) with the design is used. The fabric is placed on a flat surface or bed, and the design is transferred onto the fabric by pressing ink or dye through the screen.
- The process is done manually or with a semi-automatic machine. The fabric is carefully placed under the screen, and the ink is pushed through the screen mesh, transferring the design onto the fabric.
Advantages:
- Great for detailed or smaller-scale designs.
- Allows flexibility for smaller batch runs and custom designs.
- Suitable for various fabric types and applications.
Digital Printing
Digital printing is a modern method of printing where designs are directly printed onto fabric using specialized inkjet printers. This process offers incredible precision and flexibility for both small and large batches.
How It Works:
- Digital printers directly apply ink to fabric, using computer-generated designs. The printer uses tiny nozzles to spray the dye onto the fabric in precise patterns.
- It's highly customizable and eliminates the need for screens or plates, making it a versatile choice for any design, even those with multiple colors and gradients.
- The process often involves pre-treating the fabric before printing to ensure the dye adheres properly.
Advantages:
- No need for screens, reducing setup costs and allowing for quick changes in design.
- Capable of printing highly detailed, multi-colored designs.
- Ideal for small batches and custom orders.
- Environmentally friendly, as it often uses less water and chemicals compared to traditional printing.
Fixing with Loop Ageing
Fixing with loop ageing is a post-printing process used to improve the durability and color fastness of the printed design. This process involves the application of heat and steam to the fabric after printing, ensuring that the colors are properly set and will not fade or wash out easily.
How It Works:
- Loop ageing involves placing the fabric into a machine that heats the fabric to a specific temperature while passing through a series of loops. This helps set the dyes into the fibers, ensuring better color retention.
- The fabric may be exposed to steam or heat in a controlled environment to make the colors more permanent and to reduce any bleeding or fading.
- Fixing is often done with a heat setting unit or a steam chamber to ensure that the dye bonds well with the fabric.
Advantages:
- Improves color fastness, ensuring prints stay vibrant through washing and wear.
- Increases the durability of the printed fabric.
- Reduces the risk of color bleeding.
