Hamilton--An Issue of Compatibility

In the ensuing posts, the issue of responsibility came up in a number of guises. Was this the fault of Adobe, for embedding color management utilities in Photoshop? The designer/client for misusing it? Or the printer for not educating or warning the client about the files and their device dependence? In my mind, the printer was guilty only of not making backups of the files. The rest of the problem is one that goes far beyond color spaces and device dependence.
