In the recent RMI newsletter Robin asks and defines the issues within this question <http://rmimaging.com/information/Chromaxion_Issue_4.pdf>. The only thing Robin seems to have missed was that by going through the Lab connection space, some colors are changed. This disrupts my color output more than anything. The problem has been shown with great specificity by Bruce Lindbloom at <http://www.brucelindbloom.com/index.html?MunsellCalcHelp.html#BluePurple>, from <http://www.brucelindbloom.com/index.html?UPLab.html>. I was told that this problem was going to be corrected by a "forthcoming" revision initiative (10 years and counting), which also seems to have gone away. Is it time to move-on to some more responsive system. Working from an iPad doesn't allow color management. Won't we need an app to do that? Slap to the forehead... or is that what Apple is facilitating -- the creation of a color management app for their app-selling-machine, the iPad? I happen to know that the original proposal for colorsync was equation-based, rather than LUT-based. The LUT technology was added so that manufacturers could differentiate their various product levels using "secret sauce" back in the 1990s. In the meantime, product levels seems to have gone away. All the highend profile engines of the past have been bought and eliminated, except for ArgyllCMS (which has always been grassroots, but now with a mini-GUI). Or, have I gotten that wrong? ColorMunki vs i1Pro vs i1Pro2 all seem to use the same profile engine in a different wrapper. Or, have I gotten that wrong? Tim Vitale Oakland, CA
