Hi Christina,

I was looking at your visual about colors and UV opacity (here:
http://christinaanderson.visualserver.com/Text_page.cfm?pID=2448) and got
confused a little bit. Are those prints from the same process with same
working paramaters and prodecures?

How Green (which is Yellow + Cyan) can hold back more UV than Yellow
alone, where Cyan is a poor UV blocker (slightly denser than Magenta as
seen from your tests)? My experience with 3 different printers taught me
Yellow is the strongest UV blocker among color inks... How come?
