At Mojoprint we use a full-color printing technique called offset lithography. The process uses 4 color inks, known as process colors — cyan, magenta, yellow and black to reproduce all the colors in your document. When you are manipulating color using software such as Adobe Illustrator or Adobe Photoshop you have the option to work in either RGB or CMYK color models and can convert images to and from one color model to the other. When designing for print, it is imperative that you design using the CMYK model.
