Whether there's a difference or not depends on your printing workflow, and on the quality of the specific printer/printer driver/profiles, etc being used. This gets complex. For instance, most of my photos are printed from Lightroom nowadays. In Lightroom, the working environment promotes *all* imported photos to 16bits per channel and the working colorspace is "Melissa" ... ProPhoto RGB with a 2.2 gamma curve. When I elect to print something, I can either let the color be managed by the print driver and its embedded routines (by default, it knows what profile to use for each of the papers you choose in the media selection), I can print "managed by printer" but override its profile choices by telling it to use ColorSync and specifying a particular printing profile. In both of these cases, Lightroom is doing a relatively minimal job of calling up the driver and sending it the print datastream as 8bit per component in sRGB colorspace. Third option is to color manage the print stream completely ... you tell the driver to do NO color management, and let Lightroom handle the translation into the printing profile for that printer/ink/paper combination explicitly, with you specifying the specific printing profile for the job. . The only way to know how to print best for your printer and work is to experiment with your printing application, printer, and papers. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
