CMYK Four-color Printing: {Cyan, Magenta, Yellow, Black(Key Plate)}
Rely on four-color ink overlay each other to produce color, means the color image must through four different colors system of dots together (C, M, Y, K)
usually the color images (not including one or two solid colors image) all can be mixed by four-color printing, suitable for printing complex color packaging bags,
CMYK ink has transparency, so some light-colored need to spot color printing, such as white color, if not, the white will become dirty, not pure. That’s why supplier will tell you that you will have to pay five plate charges, if your CMYK design with one white color.
Spot Color & CMYK Mixed Printing: In your design printing file, including the spot color process and the CMYK four-color printing process.

CMYK’s Plate Charges: no matter how complex of the design file colors , as long as it is CMYK color printing, usually calculated as 4 colors plate charges, then total charge is $100*4=$400
CMYK & Spot Color Mixed Printing Plate Charges: if your design contains a high-definition CMYK picture, and gold, white 2 colors. Then total plate charges is $100*6=$600
