An important fact when it comes to designing is that all of our images in the computer always use the RGB (red, green and blue).
We might not notice the difference at first, but any printing machine always uses CMYK (cyan, magenta, yellow and black).
So, we can design under certain type of colors in the designing programs, but once printed, it won’t look the same. So, we need to make sure that any images we have used can be converted to CMYK.
