What Is RGB
The RGB color model is an additive color model that reproduces a wide range of colors by mixing the three primary colors of light—red, green, and blue—in various ways. The primary purpose of the RGB color model is to facilitate image perception, representation, and display in electronic systems, such as televisions and computers.
Furthermore, RGB is a device-dependent color model, meaning that different devices detect or reproduce the same RGB value differently. Typical RGB devices include color televisions, video cameras, image scanners, digital cameras, television sets of various technologies, computer and mobile phone displays, video projectors, and so on.
What Is CMYK
CMYK is a subtractive color model used in printing, representing Cyan, Magenta, Yellow, and Black. These four inks create millions of colors by overlaying ink dots on white paper, deepening hues by reducing light. One of the primary uses of the CMYK color model is printing. It is the preferred mode for color printing because it enables precise color matching.
One advantage of CMYK is its ability to provide true color matching and maintain color consistency more reliably. For bulk printing, this ensures that colors remain consistent across every printed piece. On the other hand, RGB may exhibit slight color variations, which makes it difficult to guarantee color consistency. Therefore, CMYK is an ideal choice for printing.
