CMYK vs RGB
The questions have already started. The first one, and a quite good one actually, was ... why does the colour shift when moving from RGB to CMYK. Great question. Let's take a look.
Notice how small the CMYK gamut is within the larger RGB space. All of the space on the outside will have to be "mapped" or reassigned within the CMYK space upon conversion. This is when shifts happen. Knowing that it will happen is half the battle. Controlling how it happens is the other half.
This shift can make a huge difference, especially when dealing with blues and greens. In terms of identification ... we'll want to get it right.
So, when you are getting your files ready for print in your favourite publication (Evidence Magazine, or the like), controlling the conversion can go a long way in helping you make your case to your readers.
