Welcome to screen printing video tutorials. Here in this screen printing video you will learn how to make multiple screen prints on tee shirt and other screen printing article with multiple screen printed designs and multiple screen-print colors. After this tee shirt screen printing lesson you will have comprehensively learned how to screen print multiple designs screen prints with multiple colors. If you are beginners or learners of screen printing and want to learn expert level screen printing then watch our video and learn complete screen printing process better than anywhere else.
First thing in this type of screen printing is manual machine which has many screen printing stenciled screens held on it and it rotates on its axis alternatively with screen and shirts manuals rotation. This is very important for the screen printing professional but if you still using initial method of screen printing then you can also learn this screen printing technique.
But spoil me for just a moment with this brief explanation of screen-printing (serigraphy) since a few of our readers today might not be familiar with this printing process. If you are familiar by the process, jump on in excess of to the separations lesson
Preparation of Screens:
Screen printing screens; more than one depending on definition of screen print you want e.g. in this screen print above you need four screens.
Stencil on the on butter paper or plastic sheet, one complete design and other papers should have separated design parts i.e. one paper will have this complete screen print, other papers will having hand image on one paper, ‘PHISHING’ text on second paper, ban symbol on separate paper and ‘Just Don’t Click’ text on separate image but the design on all paper should be perfectly align so that if you put all paper align over each other you have complete screen print aligned.
Place the complete design paper on four screens one by one and mark uniform registration marks, so that when you place separate design papers on separate screen the design does not over lap on each other. It is tricky screen printing technique but very easy when you will do it once.
You can now expose you screen by placing design papers on it and get your screen stenciled for stenciling details watch our free screen printing tutorial about stenciling and exposing screen printing screen.
Colors Transition in Screen printing: (Multiple screen print colors)
For this purpose you should one learn RGB (Red Green and Blue) color system and CMYK (Cyan, Magenta, Yellow and Key-black color) color system, that when you mix one of more colors of specific type then what out put you get. It requires very much experience of screen printing that you learned transition of these colors this image of CMY is going to help you in color transition of screen printing.
Serigraphy: It is not known for sure how or when serigraphy or screen-printing was initial invented, but art historians similar to Anthony F. Janson trace this art form as far back as 4,000 years in China, plus thereafter throughout Asia and Japan. Silk fabric, being a primary product in those cultures, had the unique qualities of being able to be stretched very tightly, and of being somewhat resistant to discoloration. Someone discovered that they could stretch single-thread silk fabric extremely tightly across a frame and inks would flow freely through the fabric onto a substrate like other fabric or paper. They established techniques to block the flow of ink in certain areas of the silk, while allowing the ink to freely run through open areas. Thus they could block the screens with ornate designs and print those designs repeatedly. The art of serigraphy was born. (Here, you can learn more about serigraphy)
>Today’s Flat Color Screen-printing:
At right, I’ve drawn a extremely stylized diagram of how very basic screen printing works. This is a easy two-color print we’ll be using in our tutorial today.
- At the top of the stack we see the Film. This is a film positive, which is clear with the exemption of the image to be printed which is opaque. (Black) There are other methods, like painting directly onto the silk with a “hold-out” solution, but for this lesson we’re using a film, or vellum printed on a computer.
- Next, a photo-sensitive material called “photo mask” or “photo stencil”, which behaves a great deal like photo film, is exposed to strong light using the film positive as a mask. In this process the light-exposed areas of the photo-sensitive “gel” emulsion becomes hardened. The emulsion areas of the stencil which are protected by the opaque areas of the film remain unexposed plus thus soft. In the “development” stage of the process, the exposed areas of the stencil remain hardened, while the unexposed areas of the stencil soften and wash gone, forming the image areas where the inks will pass through.
- The “photo stencil” is embedded (either before or after exposure) into fabric stretched extremely tightly across the printing frame. After the stencil dries, the “Screen Frame” is pressed against the substrate (a shirt in this scenario) and ink poured onto the surface of screen is dragged across the design using a squeegee. The results are ink deposited on the shirt. And that’s how screen printing works.
Now, there are a lot of, many variations and technical modifications to this process but this is the basic method it works. Even though it’s such a simple process, it can reproduce an amazing amount of detail when done correctly. A few of the Chinese designs produced thousands of years ago demonstrate this primitive process with incredible beauty. I, personally, have used this precise scenario to run tens of thousands of prints.
Since this is not a screen printing lesson, let’s move on to making the films and separations. If you want to get into screen printing for a hobby or a business, I recommend Roni Henning’s excellent orientation into the process.
