Screen printing presses can print almost everything you see right now, and it's called a universal press. It is through the screen to the Flat Screen Printing Machine ink in accordance with the shape of the screen to leak to the printed surface of a device. so, screen printing machine how it works?

Screen printing is the silk fabric, synthetic fabric or metal mesh stretched in the frame, the use of hand-carved paint film or photochemical plate making screen printing plate. Modern screen printing technology, it is the use of photographic materials through the photolithography method of making screen printing plate (screen printing plate on the graphic part of the screen hole for the through hole, rather than the graphic part of the screen is blocked live). Printing squeegee squeegee, the ink through the graphic part of the mesh transferred to the substrate, forming the same as the original graphic.

How Does the Screen Printing Process Work?

At the core of the screen printing process is a mesh screen material that has been stretched tightly across a rigid frame. Though silk mesh was used at one time, modern mesh is often woven from polyester or stainless steel threads.

The areas of the finished design that will not receive ink coverage are masked out on the screen using a stencil. These masked sections will block ink from passing through the screen. The unmasked sections will allow ink to pass through, thus transferring the intended image onto the substrate to be printed.

Once the screen assembly is placed over the substrate, a squeegee is used to press moderately thick ink through the screen mesh. The squeegee blade, which is usually made of synthetic rubber or polyurethane, must be firm yet flexible in order to evenly disperse the ink.

As the squeegee moves across the screen, the mesh and its corresponding stencil regulate the placement of the ink onto the substrate. The thread count and the diameter of the threads in the mesh are other factors that determine how defined the final image will be.

With screen printing, colors are applied one at a time. If the printed design has multiple colors, the process is repeated using different stenciled screens and ink colors. Thus, each layer of ink color helps to create the final design. In order to produce the highest quality image, each screen used for the design must be in perfect alignment so that each color is properly placed.
