Difference Between RGB and CMY

Have you ever tried comparing actual printed images and images displayed on a personal computer? Have you ever noticed the differences in their colors? Could this be a malfunction in the printer? The answer is probably no. This is due to different types of color generation systems used between printers and PCs.

Television and Computer displays express various colors by combining three colors referred to as the three primary colors of light, namely red (R), green (G) and blue (B). Any color can be created with these three colors. In addition, mixing equal amounts of these three colors results in the color white (W).

This method is referred to as the additive color process because it represents any color by adding the primary colors together in different proportions.

The three basic colors used by printers are magenta, cyan and yellow. Any color can be printed using these three colors. Mixing equal amounts of these three colors results in the color black. This method is referred to as the subtractive color process because various colors are expressed by absorbing a portion of the color white while reflecting the remaining colors.

Tip

•For example, if magenta (M) seems to be a little too strong during printing, this can be compensated for by slightly increasing the green (G) with an adjustment of the printer.
