Design preparation: High resolution (300 DPI) image files are required, vector files (such as AI, SVG, EPS) work better.

Mesh selection: Polyester fiber mesh is usually used, and aluminum frames can maintain high tension.

Mesh number: Select the right mesh number according to the design requirements, high mesh number (such as 200 TPI) for fine patterns, low mesh number (such as 110 TPI) for bold design.

Photosensitive adhesive coating: The screen is evenly coated with photosensitive adhesive, and the photosensitive adhesive will form an ink-proof film under ultraviolet irradiation.

Exposure and washing: The design pattern is placed on the screen, exposed with ultraviolet light, and washed with high pressure water gun (1500 PSI), the unexposed part will be washed away.

Screen drying: Dry the screen in a dark environment at room temperature, the relative humidity is less than 40%, and the temperature is appropriate at 68-77°F.

Alignment and printing: the screen is installed on the press, and the test printing is carried out to ensure the alignment is accurate.

Ink preparation: Adjust the viscosity of the ink as needed, and high-quality ink can achieve bright and lasting printing results.

Printing operation: Print with the right scraper Angle (65-75°), pressure (25-35 psi) and speed (40-100 mm/s).

Ink curing: Use a flash curing device (320°F, 20 seconds) or a conveyor dryer for curing.
