Screen prints
From The Giant: The Definitive Obey Giant Site
Screen prints are prints produced by silk screen. In this process each color is applied separately, and only after the previous colors are allowed to dry. Typically, the colors are not intended to mix as with process color or offset lithographs, (IE screening blue on top of yellow will not result in green, but in yellow, just as painting over walls). Because process color mixes the layered colors, millions of color combinations can be made. Screen prints however are limited to the amount of colors you use.
