Screenprinting began in the China during the Song Dynasty (960–1279 CE) – then was later spread out to other Asian countries and Europe. The term “silk screening” has been out of fashion since the 1960′s – in the good ol’ days, people printed shirts on screens made out of silk. Now, we use a polyester mesh material and use a “squeegee” to transfer ink onto the shirt.


Every once in a while, we have a customer who comes in and asks for a shirt to be printed within 30 minutes, as if we can print out a design and just iron it onto a t-shirt. Well, today we’re going to share how it’s a bit more complicated than that. So here are some fast facts on our PROCESS of screenprinting t-shirts.
OUTLINE OF THE PROCESS:
1. Design
2. Approval
3. Art Department – art is converted, sized, separated, and printed onto film
4. “Dark Room” type process – similar to photography process
5. Screen – taped, blocked, and squeegeed through to print
6. Ink goes through dryer
*All processes must be repeated for EACH color and EACH location design entails*

1.
First, you need a design! There are certain guidelines that must be followed in order to get the highest quality image on your printed t-shirt. Check out those guidelines on our website under “Client Portal.”
2.
We have a personal proof approval process between you and a DTNtech team member - that means one-on-one contact with a functionally creative customer service rep to get your order right. If you’ve ordered from us before, you know that we require a last confirmation approval before we get your order done. It’s a very simple process – you give us the sizes, colors, locations, what you want on the shirt, what brand of shirt you like, etc., and we take it all down in a composite proof for you to see how it will look on the item. We’ll work with your artwork, and the proof will show the ink colors you want us to print, print size dimensions, and confirm the print locations you have requested for us to print.
3.
After you are completely satisfied with your proof, the final design gets sent to the art department, where sizing layouts and each color of your design is separated onto different films. The films are then transferred onto the actual mesh screen – going through a process very similar to a PHOTOGRAPHY process (dark room), and areas of the screen are blocked off with a non-permeable material to form a stencil, which is a negative of the image to be printed; that is, the open spaces are where the ink will appear.
4.
The screen then gets washed out with a high pressure washer, and when dry and doublechecked for accuracy, it is finally ready to use in press! A special type of ink called plastisol is used, then “squeegeed” onto the shirt into the shape of your design. Each color is done separately, therefore the entire process is repeated each time for every color, and every location your design entails.
5.
After each color/location is printed, it is put through a dryer to dry the ink. This makes us able to print professional quality shirts for you!

Just imagine having to do this entire process for each tshirt – you may understand why the professional process was designed for garments ordered in bulk quantity.
