"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Code below performs an approximate conversion of CMYK to RGB. It's not perfect though. See original discussion (where I found this) at

Function CYMK2RGB(c As Integer, y As Integer, m As Integer, k As Integer) As Long
Dim R As Integer
Dim G As Integer
Dim B As Integer
Dim colors As Integer

colors = 255 * (100 - k) / 100
R = colors * (100 - c) / 100
G = colors * (100 - m) / 100
B = colors * (100 - y) / 100

End Function
