UV printer printing CMYK and RGB are often encountered in English abbreviations, for some new to the line, perhaps a little strange, jeep small make up for specific explanation:

CMYK is also known as print color mode. The biggest difference from RGB is that RGB mode is a glowing color mode, where you can still see the contents on the screen in a dark room.

CMYK is a color pattern that relies on reflections. Why can we read the contents of the newspaper? It is because the sun or light shines on the newspaper and reflects the content to our eyes. CMYK can only be seen if there is an external light source. So you can't read in a dark room. Any image you see in print is represented in CMYK mode. For example, periodicals, magazines, newspapers and brochures all use the CMYK model.

CMY is the initials of three printing inks: Cyan, Magenta, and Yellow. "K" is the last letter of black and is used to avoid confusion with blue.

In theory, only three CMY inks are enough, and if you add them together you should get black. But high - purity ink is not yet available, CMY add up to a dark red. Therefore, in order to ensure the black output, also need to add a special black ink to blend.

RGB is generally referred to as the "three primary colors of color", R (red) red, G (green) green, and B (blue) blue. The color scale of RGB is 0-255. Since RGB is color light, the superposition of color is brighter and brighter, so it is also called "additive color method". White appears when the values of all three colors are 255, whereas black appears when all three values of RGB are 0. From the RGB color diagram above, it can be seen that B+G is cyan, B+R is magenta, and G+R is yellow, which is complementary to CMYK color.
