I have NEVER seen such a simple subject made SOOOOO complex. God bless you
...... What does all this have to do with Harold Wong's question? 
What are you saying, REALLY. Are you saying that what I have said wont
work??? Are you saying that you dont agree and there is another method that
is better for the situation I was responding to.  What does all this stuff
have to do with getting better scans on a LS-2000 scanner. Please enlighten
me I dont understand. 
The simple fact of the matter is that RGB and CMYK are totally different.
One is additive color and one is subtractive. Dont you think a person
starting out with all this should learn the basics color theory before he
gets involved in all this nonsence. Or are you one of those guys that
believe in all the hype that is assoated with most of the products that you
mentioned and thinks that using them will somehow make everything better??? 

Flame away!!!

 Oh Yeah..... Press Ready PU What a stink bomb!!!!!!
