</div>Actually not unless you plan on having that application apply the device profile you create. I hope that kind of workflow disappears in favor of a common profile registry that is used when printing from any application. Application-based color management has a long history of not working reliably...<br>
<div class="im"><br></div></blockquote><div> </div><div>There is clearly something to be said for system-wide transparent color management *that just works*. We all wish we had it, and I guess if the price is a sealed-tight system that needs special tools to make and install profiles that would be an acceptable price to pay. I think the very fact that many of us use Macs as personal machines proves that many things are done well and work well - be it in display or in printing.</div>
<div><br></div><div>On the other hand, as Graeme points out, cutting edge professional apps may be using cutting-edge gamut mapping, be it for the display or for the printing, and on-the fly computation may make more sense sometimes than any attempt to precompute a profile and register it on a system which is not designed for ephemeral throw-away profiles; furthermore quite a few of us on this list are somehow involved in designing CM systems and pseudo-RIPS, and we are exactly the population who may be interested in running application color management.</div>
<div><br></div><div>I would say that the criticism of third party apps not working correctly is apposite - I have seen Argyll crash quite frequently in the distant past :) - but that is the price of software in development, and not a reason to stop people from writing software. </div>
