Screen Printing Overview: How To Print A Shirt



welcome to a brief overview of how the screen printing process works presented by Rio net and silk-screening supplies comm keep in mind that this is just a brief overview and doesn't cover all the variables that often come up during the screen printing process for more information about the screen printing process visit our website at wwlp.com we carry a wide selection of training DVDs and books in addition all of our press packages we sell include an in-depth instructional DVD about screen printing the first step in the screen printing process is artwork creation if you have a multiple color image you want to use then you need to separate the image into layers so it can transpose two different colors on the printing press you can do this in different artwork programs such as CorelDraw Photoshop or illustrator if you're creating a new image for a print you must consider the image itself and how you'd like the layers to be separated here we see Ryan create a two layer and a single layer image each layer must be printed separately once the artwork is done for exposure on separate screens later once the artwork is created it must be printed onto film positives otherwise known as transparencies there are lots of options on the market for printing on transparencies and lots of methods for getting the best and darkest print possible we recommend Epson printers with the rip software for more information on outputting to film positives visit our films and output printers page on silk screening supplies calm next up in the screen printing process is screen preparation and exposure screens come with either wood or metal frames the mesh of the screen material varies depending on the type of job you are doing before you can coat and expose a screen you must degrease the screen this is a critical step in the process as it cleans all the contaminants off the screen so the emulsion will properly bond to the screen for degreasing you must use a screen printing specific degreaser first get the screen wet and then apply the degreaser product once the screen is sprayed with degreaser you want to scrub both sides of the screen to thoroughly work the degreaser into the screen and then rinse all the degreaser out of the screen once completely rinsed out place the screen in front of a fan or into your drying rack to allow the screen to completely dry after degreasing he moved to coding the screen with emulsion emulsion is UV ray sensitive so coding should always be done inside a darkroom taking special care not to prematurely expose your screen add the emulsion into your scoop coder and then apply the emulsion to the screen apply a motion to the flat side of the screen first the inside of the screen next most emotion coding only needs one pass from the scoop coder per side once the screen is coated allowed to dry in your drying wrap once your screen is coated with emotion and dried it is time to expose your artwork onto the screen lair artwork transparency onto the flat side of the screen remember to flip over your artwork so it will print correctly onto the shirt when the artwork is correctly aligned onto the screen it's time to expose the screen there are many types of exposure units on the market today Ryan is using an automated UV exposure unit manufactured by Rio net and available from our website this unit is very effective and comes with a timer for convenience and highly accurate exposure times place your screen with the artwork taped on to it face down and exposed for the appropriate amount of time for your particular screen now that the screen has been properly exposed you must take the screen and wash out the emulsion get the exposed screen wet on both sides allow the water to sit on the screen for at least 30 seconds to break down the unexposed emulsion once the screen has been allowed to sit starting with the flat side of the screen spray out the screen washing out all the emulsion on both sides leaving the image burned into the screen after the screen is washed out dab with newsprint and allow to dry in front of a fan once you've thoroughly checked your exposed screen for any errors and fix those with tape a red code block out now you're ready to begin printing first you need to set up the press with the screen on it once you've put the screen into the press you must adjust it so it is level and at the right height you don't want your screen resting directly on the shirt you are printing on too instead you want the screen raised about an eighth of an inch above the shirt you're going to be printing on use the off contact adjustments on your press to achieve this today we're printing a one color design apply spray adhesive to the plating and place your shirt centered onto the platon keep in mind that as you're setting up your job testing prints using paper or an old shirt are always essential before you start production printing your shirts in order to get the best prints possible apply a good amount of ink to the base of the screen just below your image proper squeegee technique is important to remember in order to get the best prints possible first fled your screen by moving the ink across the screen next place your squeegee at an 80 degree angle and press firmly down onto the screen so the majority of your pressure is pressing down onto the screen and then pull towards yourself with proper technique you will have very little ink left behind the squeegee as it moves across the shirt now you're ready to dry if you're needing to do more than one code or have a print that is more than one color you will often need to flash cure the ink you can use a heat gun or flash dryer for this process once the ink is dry to the touch you can apply your second coat or other color when you're finished printing onto your shirt you need to do a final cure of the shirt so the ink is completely dry for long-term use again you can use a flash dryer or conveyor dryer for much quicker more efficient drying once a final cure is done correctly the shirt is ready for wearing and will last a very long time remember this was just a brief overview of the screen printing process and for more information check out wwl screening supplies comm for a more in-depth look at the screen printing process instructional DVDs and books we have for sale and of course all the

  1. Man how time goes by! This was 8 years ago. Crazy to think we've been at it for almost 10 years now.

  2. we have seen a lot of screen printing videos of t shirts i would like to you demonstrate a video of printing flip flops

  3. Why on earth would you make a video like that? The lighting effects are seizure worthy, and only make me never want to watch your videos again.

  4. That's awesome you guys have an automated UV exposure units. I'm new at this and didn't know about these.

  5. Hi ive started screen printing recently and im pretty close to getting it right but the problem im having is when i put the paint onto the screen to apply it to the shirt it smudges the letters. Could you help me find the cause of this and prevent it any help at all is really appreciated

  6. I put twice as much water needed for emulsion… Will it still work? I filled container to top(senitizer

  7. Very informative. Thank you. Although, that was the oddest, most random visual and voice effects I've ever heard.

  8. It's easy! Mixing plastisol is all about getting your hands dirty and mixing the two colors that make your desired color. If you google "color theory" that would be a good place to start.

  9. actually i am searching on youtube about how i mix the colors to paint the t-shirts !! is there any buddy can help me? plz

  10. I watched this before when I was about 8 and i didn't understand you so i got angry at you and never wanted to hear anything about your screen printing thing but now I was wrong to be mad at you , I actually understand now 🙂

  11. muy buen video de todo el proceso de serigrafía en camisetas desde la recuperación de la pantallas hasta la impresión y secado de las camisetas

  12. porque aparecen tanatas luces y lineas???????????que confucion nome gusta nada!!! listo me voy no me gusta , con esas luces no se ve neda,,

  13. You say the emulsion process is to take place in a dark room, however there is light in the demo. Is this a special type of bulb? Thank you.
