What is RGB/CMYK?
When it comes to color based on light (otherwise known as “Additive Color”), red, green and blue are combined to create the different colors you see. As the different colors are added to each other, they create white light – hence the term “additive color.” the colors are “added” together to create white. The RGB color format is used inside television sets and computer monitors. CMYK works almost the complete opposite of RGB. There are three primary colors in this format: cyan, magenta and yellow. With color based on ink, the colors are added together to create black, subtracting from the white on the paper. This is called “Subtractive Color” – you start with white, then subtract light with ink to get black. True Black cannot be achieved with these colors, however. So, black is added – giving you CMYK (“K” is used to refer to black, so it is not confused with the “B” for blue). What is 300 DPI? Look at a digital image. You see the full image.
