Re: [To Sean]How to convert RGB to CMYK color?
Thanks a lot Sean.
Your advice is correct in theory.
What I need is practical conversion formula in printing using CMYK Inks. For example, commercial graphic softwares like photoshop are using very complex conversion math, which I wanna know.
Anyway, thanks for your kind advice and I truely appreciate it.
I hope I can help you in the future shortly.
Young... :-)

Re: How to convert RGB to CMYK color?
Does this mean
Cyan = Green + Blue, no Red
Magenta = Reg + Blue, no Green
Yellow = Red + Green, noBlue
And whatever K is is nothing...
Im confused?

Re: How to convert RGB to CMYK color?
Cyan = 255 - Red
Magenta = 255 - Green
Yellow = 255 - Blue
Black = Min (Red, Green, Blue)
Converting back to displayable colour (unlike Photoshop which after conversion,
still looks very much the same, this part i am not quite sure, rem read from
some where)
new Red = ((Cyan-Black) * 255) / ( 255 - Black )
repeat for the other two channel
hope this helps
