* Four Color Process - This is a technique where four primary colors (Cyan, Magenta, Yellow, & Black - or CMYK) are used to reproduce a full color image. This proces lends itself to full color photographic or digitally created designs because many shades and colors can be created with only four screens. 4-color process printing can produce some color variation. The colors on your T-shirt may vary slightly from the colors in the digital file. Although the colors are usually pretty close to the original file we cannot guarantee 100% color accuracy. Replacement is only at our discretion.
