Characteristics
High adhesion
It can form a solid printing layer on the surface of difficult to adhere materials such as silica gel.
Temperature resistance
It can maintain bright color and stability in high temperature environment.
Chemical resistance
It can resist the erosion of various chemical substances and extend the service life of printed matter.
Environmental protection
Usually does not contain harmful substances, in line with international environmental standards.
Silkscreen Printing
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.
Screen cleaning and recycling
After printing is completed, ink and photosensitive adhesive are removed with special cleaning agent, and the screen is properly stored after drying.
