Only broad strokes are appropriate since the user should favor the advice given by the vendor(s) of both the devices being profiled, and the supplies and tools used to attain the goal.īTW, I am not an expert on ICC profiles, but as an advanced amateur photographer, I have created them for my own system. Perhaps someone who has worked with the new digital 3-chip DLP projectors in a movie theatre could enlighten us (ew, a pun!). This topic should include only the broad strokes that illuminate the concepts of how to profile: monitor (colorimeter), printer (inks and paper), scanners (reflective IT8 for flatbed, transmissive IT8 for film), digital cameras (reflective IT8, typically in the context of a studio with controllable lighting), digital front projectors (BTW, I don't know how one would go about profiling a projector. In fact there may be no particular reason to save them once the new printer profile is created.įor final good measure, how about a topic such as:īrief Summary: How To Profile, by Device IT8 replicas are never to be reused as a new tool to calibrate yet other devices! Their only purpose is to see how close a given printer can come to the goal. IT8 calibration targets are to be stored in an archival manner between uses, just as you would (or should!) store your most precious family photos or those of your proudest achievements. This would be an overview about software and supplies, including the digital colorimeter sensor for monitors, the reflective and transmissive IT8 calibration targets for various scanners and digital cameras, high quality papers and inks for the printing of temporary IT8 replicas, and comments explaining why the same paper and ink a project will be printed with must be used to print the IT8 replicas, which are in turn scanned by a recently profiled flatbed scanner (otherwise the result would be bogus) to create the profile of the printer. Tools Required To Create/Recreate ICC Profiles However, modern technology is approaching the level of incredibly good. Due to issues related to gamut, perfection is indeed elusive. ![]() The successful profile makes the device better (hopefully dramatically so) than an unprofiled unit. An alternative approach would be to redo the profiles at the beginning of each major revenue-producing project, and not worry about it for internal projects never to be seen by clients in particular or the public in general.įinally, one must not believe a profile makes the device perfect. A prudent or meticulous user, seeking excellence, might routinely schedule, as a sort of preventive maintenance, the recreation of his or her system's profiles on a monthly, quarterly or annual basis. Trouble is, whether any existing profile is custom or generic, as devices age they deviate from the "reality" asserted by the profile. (Then there is the case of digital cameras, which can benefit from profiling using the same reflective IT8 calibration target routinely applied to flatbed scanners does anyone know if any but the most expensive models are supplied with factory profiles? BTW, Wikipedia's own article about digital cameras does not mention ICC profiles.) And entry level (mass-marketed consumer) devices might well be expected to not have a profile available at all. Sometimes the profiles are even more generalized as being for any CRT or any LCD (or TFT LCD), or any ink-jet from a particular company (which assumes you are using their ink and their paper!). High end (professional-grade) peripherals typically do come with factory supplied ICC Profiles, sometimes customized by serial number, but often more or less generic by model number. Why ICC Profiles Should Be Periodically Recreated Perhaps the needed improvements might look something like this: My (fuzzy by then) thinking was that all users should be able to make their own ICC profiles if they want to, so pointing at a tool to do so seemed good. The "See Also:" about "VueScan" would make a lot more sense if the preceding article included a topic such as "Why ICC Profiles Should Be Periodically Recreated", perhaps followed by a topic such as "Tools Required To Create/Recreate ICC Profiles". The truth is, by the time I added that edit my brain was fried it was a last ditch effort to leave a placeholder that would remind me to deal with it later if someone else did not run with it first. ![]()
