Yes. This process uses CMYK printing whereby only 4 ink colors are used. Cyan, magenta, yellow and black are layered over each other to print a full range of colors. Exact PMS matching is not possible and this type of printing is not a good choice when there are large solid areas of color in the design. Additionally, USCW only prints 4 color process on WHITE shirts. If you require process printing on colors, we can utilize a process called Spot Process. There is an additional charge of $15.00 for art separation when 4 color process printing is requested.
