Kai-Uwe, <div><br></div><div>I am sorry I replied very hurriedly to your message. You are surprised that at Gutenprint we are so eager to resort to profiles. Please let me explain a bit more. The reason is that (hopefully) this will simplify the work of supporting *new* printers and media, and in fact (hopefully) will allow us to crowdsource such support. </div> <div><br><div class="gmail_quote">On Thu, Jan 19, 2012 at 7:59 AM, Kai-Uwe Behrmann <span dir="ltr"><<a href="mailto:ku.b@gmx.de">ku.b@gmx.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Am 18.01.12, 21:35 +0100 schrieb edmund ronald:<div class="im"><br> <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> The way we want to go is for Gutenprint is to be completely profile-based<br> in the future, ie. every base media type preset for new printers will come<br> with a profile.<br> </blockquote> <br></div> So you become practical your own profile vendor.

In fact it is our hope that users will help us write tools that allow optimal ink curves and such to be quickly determined for a new printer type, thereby enabling the whole community to join together to allow graphics users and in particular Linux users to have access to the newest printers. </div> <div><br></div><div>I should stress that I own various spectros, and will make "canned" bundled profiles for Gutenprint; As my instruments are very fast it takes me about 5 minutes to make a profile, so I do not expect a work overload. I will make a quick profile for anyone who sends me an A4 printed target, maybe requesting a nominal fee. Of course if someone wants a 5000 patch Atkinson target read, I may really require a fee.</div> <div><br></div><div>Profiles made with Graeme's excellent Argyll are of course entirely free of copyright issues. And I will take the distribution issues up personally with other profiling software vendors if and as they occur. Profiling tool vendors are sympathetic to us because more profiles in use means more instruments sold :) Indeed, Xrite have very kindly donated an instrument to help Robert with linearisation. </div> <div><br></div><div>Edmund</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5"> <br> kind regards<br> Kai-Uwe Behrmann<br> -- <br> developing for colour management <a href="http://www.behrmann.name" target="_blank">www.behrmann.name</a> + <a href="http://www.oyranos.org" target="_blank">www.oyranos.org</a><br> ______________________________<u></u>_________________<br> openicc mailing list<br> <a href="mailto:openicc@lists.freedesktop.org" target="_blank">openicc@lists.freedesktop.org</a><br> <a href="http://lists.freedesktop.org/mailman/listinfo/openicc" target="_blank">http://lists.freedesktop.org/<u></u>mailman/listinfo/openicc</a><br> </div></div></blockquote></div><br></div>
