The JCB will let your data shine in RGB

CMYK vs. RGB Color images are printed on paper by separating their colors into four component parts: cyan, magenta, yellow, and black ( CMYK ). Each of the colors in an image is created by assigning a percentage from 0–100 to each of the aforementioned colors (for example, a red color could be created from 0% cyan, 100% yellow, 100% magenta, and 0% black). The color image is then printed on a multipass or multiplate press, with a single piece of paper receiving ink from each of four plates. CMYK is referred to as subtractive color (i.e., the color black is achieved by the presence of all inks), as opposed to RGB (red, green, blue), which is additive color (i.e., the color white is achieved by the presence of all three colors as lightwaves). RGB is the color process used by computer displays and can generate many more colors, and more vivid colors than those that can be generated by CMYK.
