How Can T-Shirt Screen Printing Work?

Look through your dresser, cupboard, or filthy clothes hamper, and you will likely find some screen printed t-shirts. Tees with pictures, expressions, and business logos printed on them are favorite casual shirts. Perhaps you have wondered just how those bright graphics get on these t-shirts? The most frequent procedure, screen printing, entails several steps and can be a little more complicated than you may think.


Any screen printed t-shirt starts with the plan. A digital art file in vector format, like.EPS or.AI, is the simplest to use, as it can be enlarged or reduced to the specified imprint dimension without compromising the quality. Most screen printing is completed with “spot color” layouts, meaning that the layout has a couple of different colors in contrast to the entire range of the rainbow. These colours are recognized based on the Pantone Matching System, or their “PMS colours,” which empowers an specific color match. The easiest screen printing endeavor is a one-color layout.

Then, the screens have to be generated, one per colour. A screen printing is type of like a huge stencil. It will permit the ink to be implemented exactly where it is supposed to go, and nowhere else. To begin with, a very fine net is stretched over a rectangular framework. Then the screen is coated with a photo-reactive material – which is, a material that changes when it is subjected to light. The plan is printed onto a transparent film, so light can pass through several regions but not others. Where the light moves through, the emulsion will harden, but the locations that remain dark will stay soft. Those areas are coated using a high-pressure hose, which means that they become the open regions whereby ink will pass on the t-shirt.
