Bottom line, it's ColorSync and the way some profiles (V4 is more likely to break) interact with some printers in certain print pipelines.

And yet, in some testing I did with Chris Murphy, the bug didn’t show up when printing out of Preview. I’ve asked people in the past who’ve seen this issue in other applications if they indeed see it in Apple’s Preview.

In Apple’s mind, if the bug doesn’t show up in Preview, its not their issue. I’m not defending this attitude! But it is an interesting data point.

That does not preclude and app specific (back channel) fix that may have been added/tweaked in the development of OS X 10.6.x, ColorSync for the previous and Preview. It's also not 100% certain that Preview is using the print pipeline EXACTLY like other apps outside of Apple are using it. The moment multiple players get involved is the moment where FUD starts happening. But I'm still pretty sure it's something, somewhere in ColorSync that is stepping in and contributing to the issue.

Since the "simple fix" is to use only V2 ICC profiles and the fact that newer color management solutions (i1Profiler) don't seem to be at fault, I'm not sure we'll ever know for sure. But the fact that the "issue" has not appeared on Windows when using all the various components are in play suggests to me it's Apple's problem to fix. If Apple can't figure it out, who else can? It's Apple's print pipeline that is breaking down. (and yes, I've talked to KL about this...he's noncommittal as one would expect).

True but unless the other players are sure that Apple hasn’t provided this recommended approach, Apple’s take is, the other guys are doing it wrong, its their bug. Again, I’m not saying Apple is blameless but if their application (s)* don’t exhibit these issues, they are not going to even come to the party and aid the other players.

*Note, if you can get Aperture to behave differently than Preview or iPhoto, now we have something to take to Apple.

For that to be true and for Apple to admit it, their applications would have to exhibit the same issues. At least with Preview and the last round of V4 profiles Chris and I tested, that wasn’t the case.

Now maybe this print pipeline isn’t defined. If so, Adobe, Epson, Canon etc need to make that clear.

Andrew, at least you and Jeff are talking about this.  That's good news to me and I'm hoping (I know, probably uselessly) that the "chatter or noise" here and elsewhere will eventually hit the ears of Adobe, Apple, Epson, Canon, etc. and get them to pay a little attention.

hi see all my comments on many forums.   my problems were there even with version 2.4 profiles only when I went to colorvision/datacolor 2.0 profiles did the problem disappear... 

http://forums.adobe.com/message/3172530#3172530

many others have this problem   only three solutions drop the profiler profiles, create a canvas setting to match size of paper or go to spyder.

maybe one day someone from the companies in question will listen....
cheers elo  yes it only occurs with snow leopard...    but why not all suppliers of profiles??

initially xrite replied and listened then they disappeared....

one more thing.   no problems with any profile when using Aperture or Lightroom.....look how they both set the margins of the pages when you place an image ..     

they both (if I read it right) set paper margins at the image of the photo/whatever.   thus no problem...

likewise if I use photoshop elements release 6 the problem does not appear...  only Photoshop CS5 and PSE9 exhibit the problems..(oh my  once again adobe is the common element along with xrite) 

Hi guys   I am fishing more details for someone to fix this issue. 

in the meantime  my problems went away with spyderprint...........and all software works.......
