How well will what I see on my monitor match what I see on paper?

The technology of design, layout and printing has come a long way to the point where much of the work is done in a WSYWIG (What You See Is What You Get) digital environment. However, there are sometimes noticeable differences in color calibration and spatial conformity from monitor to monitor and consequently from screen to print.

CMYK refers to ink colors Cyan, Magenta, Yellow and Black – these are the four process colors used in full color printing.

RGB
The colors of light – Red, Green, Blue on a computer monitor. One of the most difficult aspects of desktop publishing in color is color matching – properly converting the RGB colors into CMYK colors so that what gets printed looks the same as what appears on the monitor.
