Setting Correct color mode
Always convert your images to CMYK color mode before printing. CMYK printing cannot always match colors in RGB. After conversion, an image color may shift. Refer to the Setting Brightness & Contrast or Getting the Best Color sections for post-conversion tips.
Choosing the Right Black Settings
The four-color printing process offers a variety of choices for printing black, which should be chosen with your file type in mind.
What is the difference between Flat and Rich Black?
Flat Black uses black ink only. Rich Black uses cyan, yellow and magenta inks in addition to black ink. Rich Black prints more vibrantly, but Flat Black prints more precisely.
