Maybe there should be.
Ah, OK they are not unhappy, you are, so they should be too?
For example, Epson only sells PK papers with gobs of OBA's and their media presets are tuned to the respective whitepoints. Unless you really work at it, you won't achieve B&W output without toning crossovers. It shouldn't be this hard.
Nothing stops them from using 3rd party papers! The points I made was, its possible, people use them, people find the media settings work reasonably well and don’t complain (but you think they should). Now maybe most of these users don’t have the standards you do, that’s fine. You appear to want to dink around for a day making custom settings, that’s great. So all the other Epson users who don’t are then what, wankers?
This kind of goes back to the QTR vs, using the ABW as designed. You want to use QTR, great. Not going down that path isn’t the same as saying ABW is broken in CS5. Its a trade off.
Some folks are quite willing to spend a lot of money on a 3rd party driver like ImagePrint. But that doesn’t mean those that don’t are foolish or are unhappy with their output. While I’m a fan of IP for some of the stuff it does, its also a buggy little sucker that at times makes we want to strangle its little neck! And I suspect this bug issue with CS5 you report will make you want to strangle QTR or some other area’s little neck because again, when used as directed, ABW works just fine (for many, many users).
