The rotary screen printing process, also known as cylindrical screen printing, is a method used for printing designs on textiles and other materials. It is a popular choice for mass production due to its high efficiency and consistent quality. Here’s a brief introduction to the process:
Setup: A cylindrical screen, also known as a rotary screen, is used in this process. The screen is made of a fine mesh fabric stretched over a metal or plastic frame. The design to be printed is burned onto the screen using a photosensitive emulsion, creating a stencil.
Ink Application: The fabric to be printed is wound onto a roller and passed under the rotary screen. As the screen rotates, ink is forced through the mesh onto the fabric by a squeegee or scraper. The areas of the screen that do not have the design do not allow ink to pass through, resulting in a clear and precise print.
Drying and Curing: After the ink is applied, the fabric moves through a drying tunnel or under heat lamps to dry and cure the ink. This ensures that the print is fixed onto the fabric and does not wash out.
Repeating the Design: The fabric continues to roll through the machine, and the process is repeated for each color in the design. Multiple rotary screens may be used in sequence to apply different colors.
Quality Control: The printed fabric is inspected for any defects or inconsistencies in the print. Any issues are corrected before the fabric is finished and ready for use.
Rotary screen printing is suitable for a wide range of fabrics and can produce vibrant, detailed prints with excellent color consistency. It is commonly used for printing patterns on clothing, bedding, upholstery, and other textile products. The process is fast and efficient, making it a popular choice for high-volume production runs.
