How Does T-Shirt Screen Printing Work

Most screen printing is done by "spot color" design, which means the design has several different colors than the full spectrum of rainbows. These colors are identified based on the Pantone Matching System, or "PMS color", which allows precise color matching. The simplest screen printing project is a one-color design.

Any screen printed in T-shirt starts with design. Digital art files in vector format, such as. EPS or.AI, are the easiest to work on because they can be enlarged or reduced to the desired print size without reducing the quality. You can check out unique styles of custom made shirts printing from various online sources.

Next, the screen must be made, one per color. This will allow the ink to be applied exactly where it should be, and elsewhere. First, a very fine net is stretched over a rectangular frame. Then the screen is covered with photo-reactive substances – namely substances that change when exposed to light.

 The design is printed on a transparent film, so that light can pass through several areas but not others. Where the light passes, the emulsion will harden, but the area that remains dark will remain soft. These areas are sprayed with a high-pressure hose so that the open area where the ink will flow into the t-shirt.
