The T-Shirt Printing Process

STEP ONE – Make your order.

You’ve decided you want some t-shirt printing done for some upcoming occassion, club, sports team, or something else. You contact your shop to place the order and the San Diego, CA t-shirt printing process is set into motion. When you order your shirts, you will have to decide on the:

  • What color, brand, style, and material the shirts will be
  • Ink type and color(s)
  • The design you want printed

If this already feels overwhelming, don’t fret! STL Shirt Co. can give you advice and help through every step of the t-shirt printing process. Our expert screen printing artists and designers are at your disposal. Need help designing a logo that perfectly captures your vision? You can work with our professional design team. Our experienced staff can advise you on the best shirt or combination of colors to use for your order.

STEP TWO – We make the screen

Once you have created your design, we go about making the screen that will be used to print the design on your shirts. First, we print the design on a transparent sheet of film. Based on your unique parameters, our t-shirt printing staff will select the best mesh screen for your order. We then coat that screen with a substance called emulsion, which is sensitive to light. We place the film with your design on it on the screen and the screen is exposed to light. Light is blocked from reaching the screen wherever the design is on the film and the rest of the emulsion hardens in the light. This is how we create the stencil.

If you want a design using multiple colors, we repeat the process above, making a screen for each color in the design.

STEP THREE – We print.

Then, it is time to add the ink. T-shirt printing and other screen printing usually uses a special ink called plastisol. You might have noticed that the prints on shirts are slightly textured, a little rubbery, but still smooth and flexible. That’s plastisol for you. Plastisol is ideal for screen printing because it withstands washes, moves with the fabric material of your shirt, and shows up vibrantly on any color t-shirt.

The screens we made are attached to a printing press, and each shirt is placed on a plate below. We work deliberately to line everything up precisely so we know that your design will end up in the right place on your t-shirt. We apply ink onto the screen and use a squeegee from end to end of the screen to smooth and press the ink onto the shirt. We repeat this for every single t-shirt we print, and if your design has several colors, we repeat it for each color on every shirt. It takes skill to get the ink just right so it shows up nicely and keeps the sharp lines from your original design. Lucky for you, our t-shirt printing team has mad skills.

STEP FOUR – The ink cures.

Now your awesome design is on your shirts! We aren’t quite done, though. After the ink is applied, the ink has to cure. This means the ink must be transformed into a solid so it stays on your t-shirts. In order to do this we introduce the ink to heat. It takes research and trial and error to perfect the curing process. It is easy to damage the shirt or the print if you use the wrong temperature or cure it for the wrong length of time. You can rest assured that we have the curing process figured out, so you know your prints will come out great.

STEP FIVE – You get your shirts!

Once the ink is cured, it means that your t-shirts are officially printed! Next, we fold them up neatly and pass them off to you. We can have your shirts or other items printed and packaged within just a few days. If you need it, ask us about shipping your order to you. If you find your self in a tight spot and need your t-shirts printed even faster, we even offer rush printing services.
