However, the principal remains the same and has been used to create high fidelity images for centuries. Now, of course, the process has become more widely mechanized and many companies that print large quantities of fabrics and garments tend to use automated screen printing presses to achieve faster and more reliable results. This is Silkscreen Printing in its purest form. A rubber blade called a squeegee is then used to push the mesh down towards the surface, squeezing the ink into the garment in a controlled process to ensure nice clean lines and prevent blotting which can ruin the design.This fills the openings in the mesh with ink in the exact shape of the design. force pulls the fill bar to the front of the screen. Then they apply a slight amount of pressure to pull the fill bar, which is attached to a reservoir of ink) from the back to the front of the screen. The printer lifts the screen to prevent contact with the surface beneath.A floodbar (usually made from aluminum) is used to push the ink through the holes in the mesh. The screen is placed on a firm foundation and a layer of ink is placed on top of the screen.Tape or “block out” pens are used to prevent this. The screen is checked for “pinholes” in the emulsion which may cause unwanted leakage.The fabric to be printed is placed on a surface called a pallet which is coated with tape to prevent ink spillage onto the palette and any future garments which may be placed on it.The soft emulsion is then washed away using a water spray, leaving a clean area in the mesh in the shape of the image which will be printed.This creates a hardening in the emulsion where it has been exposed while the rest of the screen is left soft.When dry it is then exposed to UV light through a film printed with the requisite design.
A screen made of (usually) polyester or nylon mesh is stretched tightly over a frame.
The silkscreen printing technique is as follows: The ink stays on the t-shirts for many years, they are very lasting and durable, and this method is use for mass production instead of printing just 1 or 2 products, as this printing method need a template/mould (a printed mesh with the design is needed). Silkscreen printing is a printing technique whereby a mesh is used to transfer ink onto the product(such as t-shirt etc).
