Applications
FAQ
What garments and fabrics is this DTG pre-treatment spray machine suitable for?
This DTG pre-treatment spray machine is designed for a wide range of garments commonly used in DTG printing, including cotton and cotton-blend fabrics. It supports both light and dark garments and is especially suitable for DTG white ink printing, where consistent pre-treatment application is critical for print quality.
How do I adjust the spray amount for different fabrics or colors?
The spray amount is adjusted by controlling the spray speed, which allows operators to regulate how much pre-treatment solution is applied to the garment. Lighter fabrics or light-colored garments typically require less pre-treatment, while darker garments and DTG white ink printing may require a higher spray volume. Operators can fine-tune the settings based on fabric absorption and printing requirements.
What is the difference between single and dual spray modes?
Single spray mode applies a lighter amount of pre-treatment and is suitable for applications that require minimal coating. Dual spray mode applies a heavier and more even layer of pre-treatment solution, making it ideal for dark garments and DTG white ink printing. In most production environments, dual spray mode is recommended for more consistent results.
How do I clean and maintain the spray system?
The machine features an independent liquid system with separate lines for pre-treatment solution and cleaning liquid. After daily operation, users can switch to the cleaning line and use the built-in cleaning function to flush the nozzle. Regular cleaning helps prevent nozzle blockage and ensures consistent spray performance during long-term use.
Can I use different brands of pre-treatment solution with this machine?
The machine is compatible with most DTG pre-treatment solutions commonly used in the industry. However, it is recommended to use high-quality, properly formulated DTG pre-treatment liquids and follow the supplier’s usage guidelines. Using unsuitable or overly viscous liquids may affect spray consistency and nozzle performance.
