Conversely, for any print job, when the user selects the values of all of the print parameters and selects the media to be used -- those selections point to a profile.</div> <div> </div><div>Keep in mind that the profiles for printing are not 'printer profiles' --- rather they are print condition profiles. The selection of the correct profile for a print job depends on the paper, ink, and other driver settings as well as the print device itself.</div> <div> </div> <div>Best regards,</div> <div>Ann L McCarthy</div> <div>Imaging Systems R&D</div> <div>Lexmark International, Inc.</div><br> <br><br><div class="gmail_quote">On Tue, May 3, 2011 at 12:25 PM, Richard Hughes <span dir="ltr"><<a href="mailto:hughsient@gmail.com">hughsient@gmail.com</a>></span> wrote:<br><blockquote style="margin: 0px 0px 0px 0.8ex; padding-left: 1ex; border-left-color: rgb(204, 204, 204); border-left-width: 1px; border-left-style: solid;" class="gmail_quote"> On 3 May 2011 17:08, Jan-Peter Homann<br> <div class="im">> Here, the idea of embedding the driver settings into the ICC profile via<br> > dictType Metadata is a very big help.<br> <br> </div>Does it make sense to embed it into the ICC profile itself (i.e.,<br> changing the on disk file, and changing the checksum) or just to save<br> it as metadata on a meta-profile object such as used in colord?<br> <br> This is the sort of metadata that is added using SetProperty() and<br> stored in the persistent database that is optionally stored across<br> reboots and device hotplug events.
