Screen printing, or silk printing, is an ancient method associated with printing on any material. With new machinery, it is even possible to print on cylinders that, with the old thermal printing strategies, would not be possible. The first silk used for heat has now been replaced with a nylon material that has a terribly tight mesh. It will continue to have the texture and appearance of silk.
The heat printing is stretched over a frame, typically a wood product. It is a kind of screen window that you would simply have in your home, although the heat press machine is much tighter, which means that the fabric is much closer. The screen is coated on each side with a product known as “emulsion.” The emulsion could be a light-sensitive material that can coat the nylon mesh. Once exposed to lightweight, the emulsion hardens and adheres to the screen mesh. Nothing happens with the emulsion wherever the lightweight cannot reach it and then it is washed.
The process involves three basic steps. One is to organize your design, image, or text and acquire what was created in a part of the movie. This movie is evident with the design or the black text. The second is to put this movie in the foreground of your screen and expose it to a light supply for a predetermined amount of your time. Third, you will place your screen on the fabric on which it will be written and drag ink on it with a squeegee.
Let’s say we would like to print the letters “ABC”. We could start by making a part of the movie that has all three letters, probably in the center. The three letters would be black in this movie and, therefore, the rest would be clear.
This piece of film is ordered on the screen and a piece of glass is ordered on it to prevent everything from moving.
After exposing this to lightweight, clear areas of the film can harden the emulsion and create it permanently on the screen. Once exposed, the screen is washed with running water and, therefore, the emulsion components that were not exposed to lightweight can be washed. During this situation, we can have our letters “ABC” on our screen where the ink can experience and print regardless of whether the material is under it as a result of the unexposed emulsion being washed.
If we have the tendency to want to print each of the letters in an extremely different color, maybe red, white and blue, we might want a separate screen for each of the 3 letters, however, we could have each letter inside the correct place to that did not print on the cousin of each alternative or out of place. The simplest thing to do with our “ABC” situation is to align the 3 separate screens to block the “B” and therefore the “C” with paper or tape and simply expose the “A”. We will decide on our red screen.
We will block the “A” and, therefore, the “C” on our next screen and decide that our blank screen. Currently, we will block “A” and “B” and decide that this is our blue screen. Currently, we have three separate screens, each in an extremely separate frame and each with a part of our “ABC” image. We tend to create 3 movie elements separately, all with a single letter; however, more materials are needed.
When printing this “ABC” image, we will print the “A” screen, then the “B” screen, and finally the “C” screen to return with our three-color images. Care must be taken when registering its closure in the same precise place when all the texts and images on the screen are displayed within the correct places on the finished product.
