How Does Automatic Screen Printing Work?
Automatic screen printing involves a step-by-step process that utilizes specialized equipment to print designs onto various materials. Let’s explore each stage in detail:
The first step in automatic screen printing is preparing the design. This involves digitizing the artwork and separating colors into individual layers. Design software, such as Adobe Illustrator or CorelDRAW, is commonly used for this purpose. Once the design is ready, it is exported as a high-resolution file in a compatible format for the automatic screen printing press.
Next, screens are prepared for the printing process. Screens are made of a mesh material stretched over a frame and coated with a light-sensitive emulsion. The design file is then transferred onto the screen using a process called “burning.” Ultraviolet light is used to expose the emulsion, creating a stencil of the design on the screen. After exposure, the screen is washed to remove the unexposed emulsion, leaving behind the stencil.
Before printing can commence, the ink must be mixed to achieve the desired color and consistency. Automatic screen printing presses typically have a built-in ink mixing station, where ink pigments are measured and mixed according to the specified color formula. This ensures consistent color reproduction throughout the printing process.
Setup and Registration
Once the screens and ink are ready, the setup process begins. The screens are attached to the print heads of the automatic screen printing press, and each screen is aligned with precision to ensure accurate registration. Registration refers to the proper alignment of each color layer in the design, ensuring that the colors line up perfectly during printing.
With the setup complete, the printing process can begin. The material to be printed is placed on the printing platen, which is a flat surface that holds the item in place during printing. The automatic screen printing press then lowers the screens onto the material, and ink is pushed through the stencil openings using a squeegee. The squeegee moves across the screen, applying even pressure to transfer the ink onto the material. This process is repeated for each color layer in the design until the final product is complete.
Drying and Curing
After printing, the ink needs to be dried and cured to ensure durability and washability. Different inks require different curing methods, but commonly, the printed material is passed through a dryer or conveyor belt with a heat source. This heat cures the ink, bonding it to the material and making it resistant to fading or washing out.
