Handling complex patterns in screen printing requires skill and careful preparation

High-quality photosensitive adhesive: The use of high-quality photosensitive adhesive is the basis. It can ensure the clarity and print durability of the template, which is especially important for complex patterns.

Fine mesh selection: Choose the appropriate mesh density according to the complexity of the pattern. More delicate patterns require finer mesh, but the passability of the ink must also be considered.
Printing cleaning and exposure: Make sure the glass surface before printing is clean and dust-free, and the light during exposure is uniform to avoid dew points. After exposure, the dew point is patched and a second exposure may be required to enhance the stability of the stencil.

Pattern adjustment: For small parts of the pattern, such as text or lines, appropriately expand their size to avoid details that are too thin to be clearly presented during the printing process. Especially for text with extremely fine lines like Song font, you need to be especially careful.
Printing table and suction device: Use a printing table with suction function or apply glue on the printing table, which helps to reduce the movement of paper or fabric and ensure precise alignment during printing.
Ink preparation: Correctly adjust the thickness of the ink. For complex patterns, slow-drying solvents are more suitable to prevent fast drying from causing paste. Slow drying ink allows for finer detail printing and adjustment time.

Color separation and overprinting: Complex patterns usually require color separation processing, and each color requires a separate screen template. When overprinting, precise alignment of the individual color layers is critical and requires experience and skill.
Care and maintenance: After each printing, clean the screen correctly, use screen cleaning fluid to remove ink, and keep the screen clean and intact for reuse.
Patience and practice: Printing complex patterns often requires multiple attempts and adjustments. Patience and practice are the keys to mastering these techniques.
With these techniques, even complex patterns can be reproduced well by screen printing, although the process can be more time-consuming and challenging than printing solid colors or simple patterns.
