Screen printing is a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Ink is forced into the mesh openings by the fill blade or squeegee and by wetting the substrate, transferred onto the printing surface during the squeegee stroke. As the screen rebounds away from the substrate the ink remains on the substrate. It is also known as silk-screen, screen, serigraphy, and serigraph printing. One color is printed at a time, so several screens can be used to produce a multi-colored image or design.
Here are detailed instructions on how to create your file for screen print.

Print Trapping – an acknowledgment that no printing process is perfect. It compensates for mechanical shifts or stretching of paper or plates in the printing process and provides an overlap of colors to prevent unprinted paper from showing in the final printed product.
Separations – To reproduce color and continuous-tone images, printers usually separate artwork into four plates (called process colors)—one plate for each of the cyan, magenta, yellow, and black portions of the image. You can also include custom inks (called spot colors).
Spot Colors – In offset printing, a spot color is any color generated by an ink (pure or mixed) that is printed using a single run. The widespread offset-printing process is composed of four spot colors: Cyan, Magenta, Yellow, and Key (black) commonly referred to as CMYK.
