Answer:
CMYK
Explanation:
Monitors typically use RGB color (additive model — adding to make white), but offset printing uses CMYK pigments (subtractive color — subtracting from the existing white). Printed images have less visual range, saturation, and contrast than digital images, so in print, colors will usually appear darker and less vibrant.
