Colors can vary from screen to print. How would you choose which color mode is best for a project? Describe gamut and why some colors that we see on our monitor can’t be reproduced in print?

When choosing what mode to work in for a project I always think in terms of “How is the piece going to be produced” If the project is for web, or screen view I would work in RGB Colors. However, if the final piece is going to be printed, I would work in CMYK. Although working in CMYK will eliminate certain colors, as well as, Photoshop filters available, it is best to set up an offset printing file properly in CMYK. Unless I know for sure the final piece is going to print, I tend to use RGB. I do this because, there are more colors available and the art is more vibrant on screen. There are also more options for filters working in RGB and I can always convert the file in the end if I need CMYK.

One major issue with printing is the colors on your screen regardless of what mode you are working in do not show up the same when printed.

See a great example of CMYK Subtractive Color:
See a great example of RGB Additive Color:

The reason for this is a screen emits light and, ink on paper absorbs light. When you consider how its two completely different methods additive color and subtractive color it does make sense why colors would not reproduce exactly the same. It is very important to understand this as a designer. Unfortunately, as many times as you explain it to clients some they will never grasp this concept. When working on printed project, having printed proofs is very important.
