The most common form of commercial T-shirt printers/t shirt printer decoration is screen-printing. In screen-printing, a design is separated into individual colors. Plastisol or water based inks are applied to the shirt through mesh screens which limits the areas where ink is deposited. In most commercial T-shirt designs/t-shirt design printing, the specific colors in the design are used. To achieve a wider color spectrum with a limited number of colors, process printing (using only cyan, magenta, yellow and black ink) or simulated process (using only white, black, red, green, blue, and gold ink) is effective. Process printing is best suited for light colored shirts. Simulated process is best suited for dark colored shirts. Very few companies continue to use water-based inks on their shirts. The majority of other companies that create shirts prefer to use plastisol due to the ability to print on varying colors without the need for color adjustment at the art level.

t-shirt printing is more efficetive than screen printing, and could printed any design on the t-shirt. Could customized the t-shirt!
