The so-called four colors are: cyan (C), magenta (M), yellow (Y), black (K) four inks, all colors can be mixed by these four inks, and finally realize color graphics. CMYK printing is also the most common printing, and the effect printed on different substrates is different.
Spot color printing means that a special ink is used to print the color during printing, which is brighter than the color mixed with four colors. Commonly used are special gold, special silver. There are many spot colors. You can refer to the Pantone color card. Spot colors cannot achieve gradient printing. If necessary, four-color printing can be added.
